How do I understand this kind of output?

import re pattern = r"[aeiou]" hello = re.search(pattern, "grey") print(hello.group) >>> <built-in method group of re.Match object at 0x02F2C6B0>

group() is a method of the.Match, so you should be calling it as a method and not printing the function itself. print(hello.group(0))

hello = re.findall(pattern, "grey") print(hello)

In addition: You should never use group() alone because it will raise an exception if the pattern doesn't match the string if hello: # there is a match print(hello.group(0)) else: pass # no match => no group(0)
