Substrings are basically part of a string. Many a time, we are required to extract a portion from a string and do some operation on that. Let us cite an example to see that. Example:“Coding in Python is fun.” Substrings in Python For having a substring, we need to have a string...
For example:“This is great work. We must pursue it.” is a type of string, and part of the string “We must pursue it” is a type of substring. In Python, a substring can be extracted by using slicing. Many times, programmers want to split data they have into different parts for...
