I know this is a similar post to How to check if text is "empty" (spaces, tabs, newlines) in Python? , however I'm still having troubles.

I don't understand how to use it, I'm trying to check if a variable, which contains a string, consists of only spaces, tabs and newlines. How would I use issppace() as I'm confused with it always being False?.

Help would be much appreciated.

    Show some actual code, what you expect, and what you get, otherwise we can only guess – Chris_Rands Mar 16 '18 at 16:21
  • have you tried using string.strip and seeing if that's empty – L_Church Mar 16 '18 at 16:21
  • My guess: " I'm trying to check if a variable, which contains a string" you have something like a list of strings and you want to check if any/all of them are empty/whitespace – Chris_Rands Mar 16 '18 at 16:21

    Are you sure that the string "only consists of space, tab and newline"? There might be other non-printable characters in the string, like `\x00`, that are not spaces. What does `repr(your_string)` or `[ord(c) for c in your_string]` print? You could also use `[(c, c.isspace()) for c in your_string]` to find the culprit. – tobias_k Mar 16 '18 at 16:27

  • @Chris_Rands yeah you are correct – ProTechXS Mar 16 '18 at 18:02

You can use:

if string_to_check.strip():
    print("Contains characters")
else:
    print("Contains no characters")
