python – How do I find and remove a group in a regex?

Question:

There is a file with html code. You need to find all tags with style="" and remove style="" I tried to write, something like that turned out.

import re
pattern = 'style="(?P<text>[(\w;:-)]*)'
re_style = re.compile(pattern)

with open('index.html', 'r') as open_file:
    for line in open_file:
        if re_style.search(line):
            print(re_style.search(line).groups())

But style="(?P<text>[(\w;:-)]*) searches up to the first non-letter. To search for text in style="" I wanted to use groups, but then how can I remove the found group from the string?

Answer:

Can someone help.

import re
import sys

def replaceLine(fileName, sourseText, replaceText): 
    file = open(fileName, 'r')
    text = file.read()
    file.close
    file = open(fileName, 'w')
    file.write(text.replace(sourseText, replaceText))
    file.close

pattern = 'style\s*=\s*"([^"]*)"'
re_style = re.compile(pattern)

with open(sys.argv[1], 'r') as open_file:
    for line in open_file:
        if re_style.search(line):
            replaceLine(sys.argv[1], re_style.search(line).groups()[0], '')
