Python regular expression zero or more occurrences
match, python, regex
Solution
You left a mandatory space after the `t`. Remove it and you'll be fine:
I can\'?t(.*)
Also note that the brackets are only useful if you want to use the content of the first capturing group, if not you can safely remove them.
Problem
`I can\'?t (.*)` My regex is of the above form. But my match object doesn't match if the string given to it ends after `t` `re.compile(r'I can\'?t (.*)').match(str)` If str = "I cant", it doesn't work. But if str = "I can't use", it works (match returns something).
