we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...
Check if a String is Empty or Whitespace in Python Using the Equality Operator To check if a string is empty using the equality operator, we can just compare the string with another empty string. If the result is True, the input string is empty. Otherwise not. input_string="" print("Th...

This will return False if the string contains any characters other than lowercase characters; otherwise, True will be returned. Example In this program given below, we are using the regular expression ?[a z]+$' to check whether the given string is lowercased or not. Open Compiler import re...
