Extract Substring which is between String

Question

Suppose I have a string "Amar Kulkarni is a Good Boy."

I just want the string between "is an" and "."(a Dot)

I have tried using

    import re
    finalresults = re.search('is an(.+?).', results)
    print(finalresults)

But, it doesn't seems to work out. Help Please.

In regexes, the `.` means "any character". If you want a literal `.` character, you need to escape it: `\.`. — gen_Eric, Jul 10 '20 at 14:47

In this particular example, _nothing_ is between "is an" and ".". Your string says "is _a_". — Chris, Jul 11 '20 at 12:13

You have to escape the . using \, Try :

finalresults = re.search('is an(.+?)\.', results)

Note that . is always a wildcard until you escape it.

This regular expression uses Positive lookbehind and Positive lookahead to match the string.

r'(?<=is an).*?(?=\.)'

Note: this will not match is an and .

Try something like:

import re

text = 'a is an b. kk is an c.c.'
try:
     found = re.search('is an(.+?)\.', text).group(1)
except AttributeError:
     found = '' 

print(found)
