You did not escape the string literals:
>>> '"aa\"aa"' == '"aa"aa"'
True
Once you fix this for both the regex and the search string you get the
expected match:
>>> re.match('"(\\\\.|[^"])*"', '"aa\\"aa"')
<_sre.SRE_Match object; span=(0, 8), match='"aa\\"aa"'>
Raw strings make this a bit easier to read:
>>> re.match(r'"(\\.|[^"])*"', r'"aa\"aa"')
<_sre.SRE_Match object; span=(0, 8), match='"aa\\"aa"'>
