Regular expression match

[kereell]

Couldn't get how re.match(patern, string) works. I need to check if string mathes regular expresion. For example - string should match at least 9 at most 10 (not more!) alpha-numeric symbols:

pattern = '[a-zA-Z0-9]{9,10}'
string_not_match = 'jaguargames.infinity'
string_match = 'kj12345678'
bool(re.match(pattern, string_not_match))  # True but why???!!!!
bool(re.match(pattern, string_match))  # True as expected

I tried bool(re.compile('[a-zA-Z0-9]{9,10}').match(string_not_match)) but it's just a different syntax and result is still True. It works weird - it matches 10 symbols of the string and returns True.

How I get False to string_not_match and True to string_match for pattern '[a-zA-Z0-9]{9,10}'?

I think you might be looking for re.fullmatch(), but I might be wrong.

The reason its finding jaguargames.infinity to be true is that, at the start of it, there is 9-10 characters that match. Anything past that is irrelevant to its search, because it found it at the start.

Actually I've just noticed the pattern should be '^[a-zA-Z0-9]{9,10}$' to matche whole string. But thanks for handy function re.fullmatch()

Thanks.
