Questions : 2 :: What is Python? State some programming language features of Python.

Python is a modern powerful interpreted language with objects, modules, threads, exceptions, and automatic memory managements. Python was introduced to the world in the year 1991 by Guido...View answers

Questions : 3 :: Explain how python is interpreted.


Python program runs directly from the source code. Each type Python programs are executed code is required. Python converts source code written by the programmer into intermediate language which is...View answers

Questions : 4 :: What are the rules for local and global variables in Python?

If a variable is defined outside function then it is implicitly global. If variable is assigned new value inside the function means it is local. If we want to make it global we need to explicitly...View answers

Questions : 5 :: How do I test one variable against multiple values?

You misunderstand how boolean expressions work; they don't work like an English sentence and guess that you are talking about the same comparison for all names here. You are looking for: if x...View answers

Questions : 6 :: How do you split a list into evenly sized chunks in Python?


Here's a generator that yields the chunks you want: def chunks(l, n):""" Yield successive n-sized chunks from l. """for i in xrange(0, len(l), n):yield l[i:i+n] import...View answers

Questions : 7 :: Python list of lists, changes reflected across sublists unexpectedly

When you write [x]*3 you get, essentially, the list [x, x, x]. That is, a list with 3 references to x. When you then change x all three references are changed. To fix it, you need to make sure...View answers

Questions : 8 :: How do I pass a variable by reference?

Arguments are passed by assignment. The rationale behind this is twofold: the parameter passed in is actually a reference to an object (but the reference is passed by value) some data types are...View answers

Questions : 9 :: What does the yield keyword do in Python?


To understand what yield does, you must understand what generators are. And before generators come iterables. Iterables When you create a list, you can read its items one by one, and it's called...View answers

Questions : 10 :: Calling an external command in Python

Look at the subprocess module in the stdlib: from subprocess import call call(["ls","-l"]) The advantage of subprocess vs system is that it is more flexible (you can get the stdout, stderr,...View answers

Questions : 17 :: What is the purpose of self in Python?

The reason you need to use self. is because Python does not use the @ syntax to refer to instance attributes. Python decided to do methods in a way that makes the instance to which the method...View answers

Questions : 18 :: What does ** (double star) and * (star) do for Python parameters?

The *args and **kwargs is a common idiom to allow arbitrary number of arguments to functions as described in the section more on defining functions in the Python documentation. The *args will give...View answers

Questions : 19 :: Is there any way to kill a Thread in Python?
