Add a text after pattern in python

Question

Is there a way to add some text after pattern in python string?

For example I can do it easily with sed:

sed 's/my [a-z]\+ pattern/& lost_text/'

where & means the whole matched pattern.

search and man pages didn't help me :(

You're looking for re.sub:

Example:

>>> import re
>>> re.sub(r'(\d+)',r'\1--','abcd1cf123vf')
'abcd1--cf123--vf'

Oh, that was so easy. I've searched in incorrect direction. Thank you. :)

It's impossible to accept the answer immediately due to restrictions in SO engine. So I did it only now.
