Hi, I don't know the reasoning for this special behaviour of findall, but it seems to be documented explicitly: https://docs.python.org/3/library/re.html#re.findall "... If one or more groups are present in the pattern, return a list of groups; this will be a list of tuples if the pattern has more than one group. finditer is clearly much more robust for general usage. I only use findall for quick one-line tests (and there one has to account for this specificities - either by using non capturing groups or enclosing the whole pattern in a "main" group and use the first items in the resulting tuples. vbr -- https://mail.python.org/mailman/listinfo/python-list
