In this tutorial we shall be discussing about modifying the strings using different methods in regex.
1. sub() method :
This method is used to substitute or replace the matching string with other string.
2. subn() method :
This method does the same thing as sub(), but returns the new string and the number of replacements as a tuple.
3. split() method :
This method is used to split the string into a list, splitting it wherever the regex-pattern matches.
