say, when I try to search and match every char from variable length
string, such as string '123456', i tried re.findall( r'(\d)*, '12346' )
, but only get '6' and Python doc indeed say: "If a group is contained
in a part of the pattern that matched multiple times, the last match is
returned."
cause the regx engine cannot remember all the past history then ? is it
nature to all regx engine or only to Python ?
