regex - Python re.search - searching from left to right -

-

i've got small problem. i've written module parse configuration file (wvdial's wvdial.conf) using regex. file contains strings "init1 = at" , i've used following regex:

match = re.match(r'(.*)=(.*)', line)

everything worked until following line:

#init3 = at+cpin="0000"

which got parsed like:

'#init3 = at+cpin':'0000'

it seems regex engine goes right left parsing string. there way reverse re.search direction?

you need mark first * quantifier non-greedy appending ?:

match = re.match(r'(.*?)=(.*)', line)

demo:

>>> line = '#init3 = at+cpin="0000"' >>> re.match(r'(.*?)=(.*)', line).group() '#init3 = at+cpin="0000"'

by making quantifier non-greedy, regular expression engine match minimum satisfy pattern, rather maximum.
