in conjunction with loops in some programming languages. for example, in python, you can use else with a for or while loop to specify code that should run after the loop finishes, unless the loop was terminated with a break statement. why would i use else instead of nested if statements?
Syntactically, list comprehensions consist of an iterable containing an expression followed by aforclause. This can be followed by additionalfororifclauses, so familiarity withfor loopsandconditional statementswill help you understand list comprehensions better. List comprehensions provide an alternative synt...
1. Python Module FunctionsA module is a file containing Python definitions (i.e. functions) and statements. Standard library of Python is extended as module(s) to a Programmer. Definitions from the module can be used into code of Program. To use these modules in a program, programmer needs...

You can’t say in which order run() of different threads will be called. For a specific thread, it’s guaranteed that the statements inside run() will be executed sequentially. It means that first the the url associated with the thread will be fetched and only then the recieved response ...

Filtering Elements Using Set ComprehensionsYou can include conditional statements in set comprehensions to filter elements based on certain criteria. For instance, to create a set of even numbers from 1 to 10, you can use a set comprehension with an if condition as shown below −...

A function is a group of Python statements that are put together as a unit to perform a specific task. You simply enter a single Python statement to perform a task for you. By the Way: The “New” print Function In Python v2, print is not a function. It became a function when Pytho...
Such areas include except blocks and if statements that are hard to satisfy. Using Python mock objects can help you control the execution path of your code to reach these areas and improve your code coverage. Another reason to use mock objects is to better understand how you’re using their...
