multiple repeat error in python

Question

I am trying some regexes in python

re.compile('in versions: (.+?) of '+name+' ')

and, if name is 'libcrypto++', cause multiple repeat error

how can i handle it only in a string..?

Answer 1

+ is a quantifier in regex. So when you add libcrypto++ to regex string, it brings two of them alongside that doesn't make sense. See this.

To solve this you can use regex escape method, like:

re.compile('in versions: (.+?) of '+ re.escape(name) +' ')
