I need to find in a string all character sequences corresponding to sets of characters. By instance: re.findall(r"([a-z]+)|([A-Z]+)","aa BB cc DD") return: [('aa', ''), ('', 'BB'), ('cc', ''), ('', 'DD')] So it seems I can use the position in the tuple to determine which group the string is in. But it doesn't work when a sequence is in several groups: re.findall(r"([a-z]+)|([a-zA-Z]+)","aa bB cc DD") return: [('aa', ''), ('b', ''), ('', 'B'), ('cc', ''), ('', 'DD')] I would like something like: [('aa', ''), ('b', ''), ('', 'bB'), ('cc', ''), ('', 'DD')] I think it doesn't work because character 'b' is consumed by "([a-z]+)".nkss How can I do it? Thanks Continue reading...
