What is a For Loop ?
                  A for loop in Python is used to iterate over a sequence or iterable object and execute a block of code for each item in it. 
                  Here , for is a keyword where it is used to iterate over lists, tuples, strings and other iterables. 

Syntax :
Python 
for variable in sequence: statement(s)

Example :

Looping a List :
Python 
fruits = ["apple", "banana", "mango"] for item in fruits: print(item) #output apple banana mango

Looping a String :
Python 
for ch in "Python": print(ch) #output P y t h o n

Loop using Range( ) :
Python 
for i in range(5): print(i) #output 0 1 2 3 4

Using Else with for Loop :

Python 
for i in range(3): print(i) else: print("Loop completed") #output 0 1 2 Loop completed
