Here's a good function header given the following:
I wrote the below code

    import re
    from Bio.Alphabet import NucleotideAlphabet
    if ((not isinstance(pro, SeqRecord)) or (not isinstance(nucl, SeqRecord))):
        raise TypeError('_check_corr    accepts    two    SeqRecord    object.    Please    check    your    input.')
    def get_alpha(alpha):
        if hasattr(alpha, 'alphabet'):
            return get_alpha(alpha.alphabet)
        else:
            return alpha
    if (not isinstance(_get_base_alphabet(get_alpha(nucl.seq.alphabet)), NucleotideAlphabet)):
        raise TypeError('Alphabet    for    nucl    should    be    an    instance    of    NucleotideAlphabet,    {0}    detected'.format(str(nucl.seq.alphabet)))
    aa2re = _get_aa_regex(codon_table)
    pro_re = ''
    for aa in pro.seq:
        if (aa != gap_char):
            pro_re += aa2re[aa]
    nucl_seq = str(nucl.seq.upper().ungap(gap_char))
    match = re.search(pro_re, nucl_seq)
    if match:
        return (match.span(), 0)
    else:
        pro_seq = str(pro.seq).replace(gap_char, '')
        anchors = [pro_seq[i:(i + anchor_len)] for i in range(0, len(pro_seq), anchor_len)]
        if (len(anchors[(-1)]) < anchor_len):
            anchors[(-1)] = (anchors[(-2)] + anchors[(-1)])
        pro_re = []
        anchor_distance = 0
        anchor_pos = []
        for (i, anchor) in enumerate(anchors):
            this_anchor_len = len(anchor)
            qcodon = ''
            fncodon = ''
            if (this_anchor_len == anchor_len):
                for aa in anchor:
                    if (complete_protein and (i == 0)):
                        qcodon += _codons2re(codon_table.start_codons)
                        fncodon += aa2re['X']
                        continue
                    qcodon += aa2re[aa]
                    fncodon += aa2re['X']
                match = re.search(qcodon, nucl_seq)
            elif (this_anchor_len > anchor_len):
                last_qcodon = ''
                last_fcodon = ''
                for j in range(anchor_len, len(anchor)):
                    last_qcodon...

What's a good function header?
