Python in a Nutshell

Name

end, span, start

Synopsis

                        m.end(groupid=0)
m.span(groupid=0)
m.start(groupid=0)

These methods return the delimiting indices, within m .string, of the substring matching the group identified by groupid, where groupid can be a group number or name. When the matching substring is m .string[ i:j ], m .start returns i, m .end returns j, and m .span returns ( i, j ). When the group did not participate in the match, i and j are -1.
