Regex: Extract amounts in Euro

I need a Python regex which extracts amounts in €. For example:

I got inspiration from here. Based on this I have build the following regex:

^((\d[\d.\s,]*)(?:\s(?:euro|€|Euro))|\d)$

If you like to see more examples, please see the demo. The regex isn't finished yet. The problem that I face is that it doesn't match the full string.

Maybe you can help me with that? I am not an expert in regex!

You can use

^(?:€ *)?(\d(?:[. ,]*\d)*)(?: (?:[eE]uro|€))? *$

Note: if you test against standalone strings, you can replace all literal spaces with \s (any one whitespace) or \s+ (one or more whitespaces).

Details:

  • ^ - start of string
  • (?:€ *)? - an optional sequence of € and zero or more spaces
  • (\d(?:[. ,]*\d)*)
  • (?: (?:[eE]uro|€))? - an optional sequence of a space (add * after it to make it match zero or more spaces), euro, Euro or €
  • * - zero or more spaces
  • $ - end of string.

See the regex demo.
