print(element). However, metaclasses actually define the type of a class, not just a factory for it, so you can do much more with them. Lists are the most versatile sequence type. A) map may be microscopically faster in some cases (when you’re NOT making a lambda for the purpose, but using the same function in map and a listcomp). Python gives you easy ways to manipulate these files. In the simplest case, can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later. } I have a list of arbitrary length, and I need to split it up into equal size chunks and operate on it. So an iterable is an object that you can get an iterator from. { (In his opinion, the next one is more readable). [4, 5] ‘false’. This interview questions and experience are shared by one of the readers like you. I’ve got a huge list of date-times like this as strings: I’m going to be shoving these back into proper datetime fields in a database so I need to magic them into real datetime objects. This precedent was set by the standard CPython interpreter, and other interpreters have followed suit, For translation lookup in i18n (see the gettext documentation for example), as in code like: raise forms.ValidationError(_(“Please enter a correct username”)), As a general purpose “throwaway” variable name to indicate that part of a function result is being deliberately ignored, as in code like: label, has_label, _ = text.partition(‘:’). z = x.copy() # start with x’s keys and values In the class namespace A) In Python, an iterator is an object which implements the iterator protocol. A) When you run your Python program, sys.stdin is the file object connected to a standard input (STDIN), sys.stdout is the file object for standard output (STDOUT), and sys.stderr is the file object for standard error (STDERR). 128) Is there any way to kill a Thread in Python? is because Python does not use the @ syntax to refer to instance attributes. else: class a: ... – All – Experienced, Freshers and Students. Python source code (.py) can be compiled to different byte code also like IronPython (.Net) or Jython (JVM). A) A function in Python is defined by a def statement. In Python, we use name for variables. Save time in Interview preparation. data[“masks”][“id”] turbogears – A Python-based database web app framework with Ajax integration. Contents. We would love to hear more questions from you that you think are essential for evaluating Python developers.

Even if you use a exe-packager like py2exe, the layout of the executable is well-known, and the Python byte-codes are well understood. New-style classes were introduced in Python 2.2 to unify the concepts of class and type. Declaring them inside the __init__ method makes sure that a new instance of the members is created alongside every new instance of the object, which is the behavior you’re looking for. L : local, in def spam (in code3, code 4, code5). A) Python is a multi-paradigm; you can write programs or libraries that are largely procedural, object-oriented, or functional. You have [] when you should have {}. so, no wonder they’re not the same, right? Declaring the variables inside the class declaration makes them “class” members and not instance members. 19. Instead of a comprehension, you could also use itertools. . Q.1. y.list.append(2) Using new_list = my_list then modifies new_list every time my_list changes. A) Python supports different types of inheritance, they are: 70) What is superclass and subclass in Python? 150) How to count the occurrences of a list item? >>> cherrypy – CherryPy is an object-oriented web application framework. class Sibling(MyObject): >>> print “hello World” return AutoClass With data, you can now also find values like so: data[“maps”][0][“id”] I have noticed you listed Skill X on your CV. Tell me something you don't like about Python. Any problems? 69) What are the types of inheritance in Python? exec ‘self.%s=val’%(key.lower()) in locals(). A) A list is a data structure in Python that is a mutable, or changeable, ordered sequence of elements. It will likely lead to uncollectable garbage (from local variables of the stack frames that become garbage), and may lead to deadlocks, if the thread being killed has the GIL at the point when it is killed. If you want to simply type python.exe C:\Users\Username\Desktop\ you must add python.exe to your PATH environmental variable. “om_points”: “value”, >>> print mc._semiprivate “id”: “valore” It works by doing [begin:end:step] – by leaving begin and end off and specifying a step of -1, it reverses a string. Data and code are bound together by encapsulation 4. I have two iterables in Python, and I want to go over them in pairs: for (f, b) in some_iterator(foo, bar): In your case you can use setattr instead: class Song: . 123) Why does the following behave unexpectedly in Python? 119) Using global variables in a function other than the one that created them. >>> natsorted(x, alg=ns.IGNORECASE) # or alg=ns.IC A) Iteration is a general term for taking each item of something, one after another. which is not what I wanted or expected. New-style classes are created by specifying another new-style class (i.e. for i in xrange(0, len(l), n): For compatibility reasons, classes are still old-style by default. Learn Now! Traceback (most recent call last): 6. File “, line 1, in How do you append to the file instead of overwriting it? Generally, each model maps to a single database table. (To be extra-clear, the last-one-wins conflict-handling of dict.update() is what I’m looking for as well.). flatten = lambda l: [item for sublist in l for item in sublist] A) Decorators provide a simple syntax for calling higher-order functions. Get top rated python interview questions here-Also check- Job interview questions / Phd interview questions.

Check 41 Advanced Python Interview Questions You Must Know and Land Your Next Six-Figure Job Offer! Return None if the string does not match the pattern; note that this is different from a zero-length match. lock.release() A) List comprehensions provide a concise way to create lists. A) You can use dictionaries to accomplish this. However, eval seems to be considered a bad practice and unsafe to use. Do you like to participate in the analysis, design and deployment phases of a project or do you prefer to concentrate on the pure development of well-described task? It can be used for web programming (django, Zope, Google App Engine, and much more). A) The builtin data structures in Python are: lists, tuples, dictionaries, strings, sets and frozensets. , world! for (i=0; i<10; i++) printf(“.”); n = 5 if x or y or z == 2 : Note also that zip and its zip-like brethen can accept an arbitrary number of iterables as arguments. z.update(y) # modifies z with y’s keys and values & returns None Usually in cases like this, you have to make a tradeoff. 3 green brie. So it was one of the posts where we took up an essential topic for Software engineers. . That is, a list with 3 references to the same x. Then I changed one of the innermost values: myList[0][0] = 5 How do I accomplish variable variables in Python? using generators.

False In this Informative Python Series of Tutorials, Python main function was explained in detail in our last tutorial.. You can use variable key names to achieve the effect of variable variables without the security risk. This reflects the fact that all old-style instances, independently of their class, are implemented with a single built-in type, called instance. How can I call an external command (as if I’d typed it at the Unix shell or Windows command prompt) from within a Python script? Is there a special function that appends to the file? return “” + fn() + “” Python could have done something else to distinguish normal names from attributes — special syntax like Ruby has, or requiring declarations like C++ and Java do, or perhaps something yet more different — but it didn’t. redis-py is a common Python code library for interacting with Redis. Basically, a script is a text file containing the statements that comprise a Python program. If you are having trouble with buffering, you can flush the output by adding flush=True keyword argument: 141) Get the cartesian product of a series of lists? For example, int(3.15) converts the floating point number to the integer 3, but in 3+4.5, each argument is of a different type (one int, one float), and both must be converted to the same type before they can be added or it will raise a TypeError. a[-3::-1] # everything except the last two items, reversed. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. 42) What is the input function in Python?

File “”, line 1 So for the values x = 2; y = 1; z = 0, x or y or z would resolve to 2, because that is the first true-like value in the arguments. # content of its own) although it will believe it’s called ‘AutoClass’ }, The NumPy stack is also sometimes referred to as the SciPy stack. “iscategorical”: “0” It looks like some disagree that eval is ‘very dangerous and insecure’ in the OP case. This is nowhere a complete list of skills hiring managers might be looking for in a Python developer. A) Super() is used to return a proxy object that delegates method calls to a parent or sibling class of type. Second  - Interview only those relevant candidates who passed the test. that you can use to refer to the nearest enclosing function scope that has a c variable. >>> a == b A) ord(c) in Python Given a string of length one, return an integer representing the Unicode code point of the character when the argument is a unicode object, or the value of the byte when the argument is an 8-bit string. 12. A) In Python, You can force the Garbage Collector to release unreferenced memory with gc.collect(). ^ A) In Python, module is a package that contains a set of functions to do a specific task. But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen. How can I make two decorators in Python that would do the following? Core Python (I know this obvious but just to make it a quick checklist, Understanding of multi-process architecture, Should know how to build Python application, Basic understanding of front-end technologies, such as JavaScript, HTML5, and CSS3, Understanding of Systems administration and Scriptwriting, Other programming languages like Java or C++.

These tools apply functions to sequences and other iterables. d = copy.copy(a) >>> b = 256 [‘A’, ‘B’, ‘C’, ‘ D’] A) When the Python interpreter reads a source file, it executes all of the code found in it. Example: Why did it happen? Then you can use your code: with open(‘data.json’) as f: import itertools One reason for doing this is that sometimes you write a module (a .py file) where it can be executed directly. Why the leaky abstraction? Read: How to Become a Proficient Python Developer & Programmer Q12). foo.val = 5, print(‘original: %r\n slice: %r\n list(): %r\n copy: %r\n deepcopy: %r’ I’m emphasizing on bad practice because eval and exec are frequently used in the wrong place. result = [] . “id”: “valore” Actually, the old raw_input() has been renamed to input(), and the old input() is gone, but can easily be simulated by using eval(input()). def __init__(self): newattrs = {} I’m trying to make a function that will compare multiple variables to an integer and output a string of three letters. 148) Understanding Python super() with __init__() methods? strptime = “string parse time” True This byte code can be interpreted (official CPython), or JIT compiled (PyPy). Another usage of the *l idiom is to unpack argument lists when calling a function. A) Python doesn’t have variable declarations, so it has to figure out the scope of variables itself. A) I suggest ElementTree. >>> “aa” is “a” * 2 print(b) return wrapped, @makebold AttributeError: myClass instance has no attribute ‘__superprivate’ It converts the source code that is written by the programmer into an intermediate language, which is again translated into machine language that has to be executed. while True: True # This is an expected result If x is an instance of a new-style class, then type(x) is typically the same as x.__class__ (although this is not guaranteed – a new-style class instance is permitted to override the value returned for x.__class__). Some of these changes are fundamental to the new object model, like the way special methods are invoked. 10. …which should return: “Hello” It is possible because + operator is overloaded by both int class and str class. The language supports raising and catching exceptions, resulting in cleaner error handling. In Python print will add a \n or a space, how can I avoid that? >>> s2 is s1 A) A directory or folder is a collection of files and sub directories. strftime = “string format time” “””The class to store the details of each song””” 76) What is operator overloading in python? dict(sorted_x) == x. It also has a number of immediate benefits, like the ability to subclass most built-in types, or the introduction of “descriptors”, which enable computed properties. Ternary operator evaluates the statement and stores true or false values. mylist.append(“e”) A) The first argument of every class method, including init, is always a reference to the current instance of the class. >>> 257 is 257 A) The interpreter operates somewhat like the Unix shell: when called with standard input connected to a tty device, it reads and executes commands interactively; when called with a file name argument or with a file as standard input, it reads and executes a script from that file. Is there a quick function that I’m not aware of? for el in l: >>> “aa” is x * 2 Optimize it for me. 9987148 >>> ‘true’ if True else ‘false’ A) Casting is when you convert a variable value from one type to another. mini = a if a < b else b. “maps”: [ In Python 2, zip returns a list of tuples. @makeitalic Just to name a few reasons: There is almost always a better way to do it f: 3; b: 6 def wrapped(): # Will fail with an AttributeError A) The files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later (deeper) on the module search path. “iscategorical”: “0” It aims to be the fundamental high-level building block for doing practical, real world data analysis in Python. >>> a = 257 . A) The Python interactive console, also known as the Python interpreter or Python shell. type is the usual metaclass in Python. print(c) # (A) Note that match may differ from search even when using a regular expression beginning with ‘^’: ‘^’ matches only at the start of the string, or in MULTILINE mode also immediately following a newline. ], def hello(): I imagine the reason for it is that, since global variables are so dangerous, Python wants to make sure that you really know that’s what you’re playing with by explicitly requiring the global keyword. import operator The *args will give you all function parameters as a tuple: In [1]: def foo(*args): But they are rare. Preferably with an off-the-shelf solution. 1 Python interview ...
