print re.match(‘^someother’, string_with_newlines, import sys A) programming-language features of Python are: A variety of basic data types are available: numbers (floating point, complex, and unlimited-length long integers), strings (both ASCII and Unicode), lists, and dictionaries. 9987148 To get a list of tuples, use list(zip(foo, bar)). In a conditional expression I have the comparison var1 is var2 which fails, but if I change it to var1 == var2 it returns True. Unlike strings that contain only characters, list and tuples can contain any type of objects. The resulting namespace (a dict) holds the attributes of the class-to-be. x.list.append(3) A) super() lets you avoid referring to the base class explicitly, which can be nice. sys.stdout.flush() So, the difference beween end and start is the number of elements selected (if step is 1, the default). # ExampleSibling is now a subclass of both Example and Sibling (with no >>> b == a If supplying a very concise answer, please elaborate on its efficiency. Also Python 3 adds new semantic (refer PEP 3102): def func(arg1, arg2, arg3, *, kwarg1, kwarg2): File “”, line 1, in The filter filters out items based on a test function which is a filter and apply functions to pairs of item and running result which is reduce. …which should return: “Hello” type is the usual metaclass in Python. For ordered sequences, lists are more convenient than dicts with integer keys, because lists support iteration in index order, slicing, append, and other operations that would require awkward key management with a dict. CodingCompiler.com created with. 130) Why is Button parameter “command” executed when declared? A metaclass is most commonly used as a class-factory. L.append(1) What I’d like to do in this example in c: int main() { >>> x = u'[ “A”,”B”,”C” , ” D”]’ I have many rows in a database that contains xml and I’m trying to write a Python script that will go through those rows and count how many instances of a particular node attribute show up. if determine(tup): These are top Selenium with Python Interview Questions and answers, prepared by our institute experienced trainers.

Note also that zip and its zip-like brethen can accept an arbitrary number of iterables as arguments. A) My rule of thumb: __repr__ is for developers, __str__ is for customers. if n is 5: A) Like with strings and lists, we can calculate the length of a tuple by using len(). Last month, iMocha was part of the Partner Leadership Conclave organized by Microsoft. There must be a simple reference or algorithm somewhere. print ExampleSibling.__mro__.

Start with evaluating candidates with Python Online Tests. True 100000 loops, best of 3: 4.24 usec per loop In the function definition so, no wonder they’re not the same, right? Is it possible to terminate a running thread without setting/checking any flags/semaphores/etc.? >>>sys.version I’m curious to know about the actual difference between the following 2 child classes. attsToStore=(‘Name’, ‘Artist’, ‘Album’, ‘Genre’, ‘Location’) If it is a list, more memory is assigned than actually used. I’ve got a Python program where two variables are set to the value ‘public’. 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. >>> x = [n.strip() for n in x] 127) How to make a chain of function decorators? See below example, >>>import sys extend: Extends list by appending elements from the iterable. 14. single expressions), evaluates them, and returns the result to the user; a program written in a REPL environment is executed piecewise. ‘3.6.4 (v3.6.4:d047928ae3f6, April 16 2018, 00:10:25) [MSC v.1600 64 bit (Intel)]’ “parameters”: [ Text files are simple text where as the binary files contain binary data which is only readable by computer. Our online assessment platform has features like image proctoring, window violation, and powerful reports that give you a fair idea of the practical knowledge of the candidate. . By doing the main check, you can have that code only execute when you want to run the module as a program and not have it execute when someone just wants to import your module and call your functions themselves. for sub in flatten(el): >>> s1 = ‘public’ end How can I make two decorators in Python that would do the following?

In such a case, you have to use a normal if statement instead of a conditional. What should I use in place of code_to_remove_tup? >>>d=5 A) Whenever we write code for any application, it might be a good practice to delete those variables that we no longer need. 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. A) In Python, Ternary operator added in the version 2.5. Python source code (.py) can be compiled to different byte code also like IronPython (.Net) or Jython (JVM). Without coercion, all arguments of even compatible types would have to be normalized to the same value by the programmer, e.g., float(3)+4.5 rather than just 3+4.5.
