Pls could anyone explain me what is Substring of a string???

Answer 1

A substring is a section of a string.

So in the string "hello", "hel" is a substring.

a='This is an Example'

'''
here 'a' is a sting where
'This', 'is', 'an' and 'Example' are substrings
not only these every individual part of the string is a sub string like
'is an','n Exa','xampl' etc..
