Search and get a line in Python

Question

Is there a way to search, from a string, a line containing another string and retrieve the entire line?

For example:

string = 
    qwertyuiop
    asdfghj         


        

Answer 1

With regular expressions

import re
s="""
    qwertyuiop
    asdfghjkl

    zxcvbnm
    token qwerty

    asdfghjklñ
"""
>>> items=re.findall("token.*$",s,re.MULTILINE)
>>> for x in items:
...     print x
...
token qwerty
