Regex search and replace substring in Python -


i need regular expression in python.

i have string this:

>>> s = '[i1]scale=-2:givenheight_1[o1];'

how can remove givenheight_1 , turn string this? 

>>> '[i1]scale=-2:360[o1];'

is there efficient one-liner regex such job?

update 1: regex far not working:

re.sub('givenheight_1[o1]', '360[o1]', s)

you can use positive look around re.sub :

>>> s = '[i1]scale=-2:givenheight_1[o1];' >>> re.sub(r'(?<=:).*(?=\[)','360',s) '[i1]scale=-2:360[o1];'

the preceding regex replace thing came after : , before [ '360'.

or based on need can use str.replace directly :

>>> s.replace('givenheight_1','360') '[i1]scale=-2:360[o1];'
