Regex: How to say 'any number of characters of any type until x'?

[JoeB]

I want to be able to refer to any number of characters of any type (including special characters) up until a specified character, which we'll call 'x' here.

So for example: wdq3jdbmhb..s?//seuybwbxqwhdbi3

I would like to isolate: wdq3jdbmhb..s?//seuybwb

You can try something like this.

>>> import re
>>> 
>>> s = 'wdq3jdbmhb..s?//seuybwbxqwhdbi3'
>>> r = re.search(r'(^(.*?))(x)', s)
>>> r.group(1)
'wdq3jdbmhb..s?//seuybwb'

Something like:

>>> s
'wdq3jdbmhb..s?//seuybwbxqwhdbi3'
>>> match = re.match(r".*x", s)
>>> s[:match.end()]
'wdq3jdbmhb..s?//seuybwbx'
>>>
