'''
1. For Loops In Python :-

    a) "Loop is also just a programming function that iterates a statement or a number of statements based on specific boundaries under certain conditions."

    b) The statement that the loop iterated must be present inside the body of the loop.

    c) Iteration means going through some chuck of code again and again. 
    In English language the word Iteration means - The act of repeating again and again.


2. UseCases of 'for' loops ?

    a) A 'for' statement loop runs until the iteration through sets, lists, tuples, dictionaries etc.. or a generator function is completed.

    b) A 'for' statement is used for areas whereas we are already familiar with the number of iterations .i.e we already know how many iterations has to be done.


3. Syntax of 'for' loop.

            loop body
