This is a simple example where we print the string with and without trailing whitespace characters: Heres the outputfirst the original string with the trailing newline (highlighted in the code) and second the new one without it: The following video gives a short intro to the string.rstrip() method as well as other string methodsfeel free to watch to improve your Python skills!
