import re

regex = r"\"([^\"]*)(?=,)([^\"]*)\""

test_str = """
regular line, no double quotes here, as you can see
"wefrwerwe, werwerwer, wer,rrrr"
this is a line "where there, are doble qotes" and the commas should "be gone"
another line that has nothing special
"""

matches = re.finditer(regex, test_str, re.MULTILINE)
newtext = test_str
for match in matches:
    newtext = newtext.replace(match.group(), match.group().replace(",",""))    
print(newtext)

regex = re.compile('(".*?),(.*?")', re.I & re.M)

while regex.search(test_str):
    test_str = regex.sub('\g<1>\g<2>', test_str)
