I wrote the below code

    from tokenize import generate_tokens, untokenize, NUMBER, NAME, OP
    from sympy.core.compatibility import StringIO
    def _is_int(num):
        '\n                                Returns    true    if    string    value    num    (with    token    NUMBER)    represents    an    integer.\n                                '
        if (('.' in num) or ('j' in num.lower()) or ('e' in num.lower())):
            return False
        return True
    result = []
    g = generate_tokens(StringIO(s).readline)
    for (toknum, tokval, _, _, _) in g:
        if ((toknum == NUMBER) and _is_int(tokval)):
            result.extend([(NAME, 'Integer'), (OP, '('), (NUMBER, tokval), (OP, ')')])
        else:
            result.append((toknum, tokval))
    return untokenize(result)

What's a good function header?
