There are six whitespace characters in python namely space “”, tab“\t”, newline “\n”, vertical tab ”\v”, carriage return “\r”, and “\f” feed. We can use a list of these whitespace characters and a for loop to check if a string is empty or whitespace in python. For...
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...
