Python Regex exclude matches with letters after /

I have 3 strings as follows:

/foo

/foo/

/foo/bar

If the strings match the first 2 patters I want to return True

If the string has anything after the second forward slash I want to return False

My regex is 

re.match(r"^/[a-z]+/?", string)

I can't work out how to exclude the third pattern. Please help. :-)

You can use $ to denote the end of a string:

^/[a-z]+/?$

Try this pattern:

^\/[^\/]*\/?$

Explanation:

  • ^: start of word
  • \/: forward slash at beginning
  • [^\/]* any number of non-forward-slash characters. If you want this to just be letters you can make it [a-x]*
  • \/? optional forward slash
  • $ end of word - no more characters

You can try it out with your examples here, and see sample code here.
