You don't have any whitespace at the beginning nor end of the string bound to sentence. So there's nothing to strip. By the way, if you're checking such a function, it's sometimes more informative to write print(repr(sentence)) which will add quotes at begin and end, and show newlines and tabs as escape sequences. If you only want to strip from one end of the string, you'd use lstrip() or rstrip(). If you're also trying to remove characters from the middle of the string, you might use translate() or the string method replace(). For example, to remove all spaces from a string, use sentence.replace( , ) -- DaveA ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

[Tutor] String method strip() not working
I am trying to learn how to use strip() method. It is supposed to cut out all the whitespace as I read in the tutorial. But the code is not working. Here's my code: sentence = Hello, how are you? print(sentence) print(sentence.strip()) input(\n\nPress enter key to exit.) Here's it's output: Hello, how are you? Hello, how are you?
