Hi, I cannot get the difference between matchObj.group() and matchObj.group(0), Although there definitions are obvious different. And group() mentions 'tuple'. tuple means all the elements in line object?
Match Object Methods Description group(num=0) This method returns entire match (or specific subgroup num) groups() This method returns all matching subgroups in a tuple (empty if there weren't any) I run the following code. Even I add more words to line object, Both have the same output. Could you clarify this question? Thanks again. #!/usr/bin/python import re line = "Cats are smarter than dogs" matchObj = re.match( r'(.*) are (.*?) .*', line, re.M|re.I) if matchObj: print "matchObj.group() : ", matchObj.group() print "matchObj.group(1) : ", matchObj.group(1) print "matchObj.group(2) : ", matchObj.group(2) else: print "No match!!" -- https://mail.python.org/mailman/listinfo/python-list
