string The replace method can also take a callable as replacement. It is called on every pat using re.sub(). The callable should expect one positional argument (a regex object) and return a string. 556 replace('col_heading', '')\ .replace('row_heading', '') import re html = re.sub(r'col[0-9]+', lambda x: x.group().replace('col', 'c'), html) html = re.sub(r'row[0-9]+', lambda x: x.group().replace('row', 'r'), html) Notes • Regex substitution is performed under the hood with re.sub.
