A simple one liner will do it:

text = text.replace(/^(?=(?:[^,]*,){2})([^,]*),/, '$1');

Here is how it works:

regex = re.compile(r"""
    ^                # Anchor to start of line|string.
    (?=              # Look ahead to make sure
      (?:[^,]*,){2}  # There are at least 2 commas.
    )                # End lookahead assertion.
    ([^,]*)          # $1: Zero or more non-commas.
    ,                # First comma is to be stripped.
    """, re.VERBOSE)
