Format() Function in Python

Definition : 

The format function is used for printing a certain type of value held within the second bracket.

Syntax : 

print( " STATEMENT .....{}.....STATEMENT.....".format(<variable name>/ <value>)) 

Important things to remember :-

1. If we use a variable name, we should leave the brackets empty {}, rather than {<variable name>}.

2.Not only variables we can also replace constants for example : - print("Hello {word}".format(word = "world")), we will get the output as " Hello world ".

3. We can also leave the {} empty rather than replacing by a constant. For example print(" Hello {} ".format("World")), this will also give the output as " Hello world"
