Why is it different from the example on the tutorial?

Thanks. It did be caused by unclear copy&paste. I shall be careful in future.

When I enter:
>>>counter=100
>>>counter
100

When I get match result:

>>>pattern='abcd'
>>>prog = re.compile(pattern)
>>>string='abcd'
>>>result = prog.match(string)
>>>result
<_sre.SRE_Match object at 0x6ffffeda5e0>

>>>result.group(0)
'abcd'

It looks like 'result' is different from a simple 'counter' variable. I do not
yet find the definition of 'result' object. What do you call 'result' object?
Where can I find it (what topic would be in a tutorial)?

Thanks,
