its correct in python rex?

Question

pattern = r"[1-5][0-9]"
if re.search(pattern,"100"):
print("Match 1")
it supposed Any two-digit number from 10 to 59, but it matches with 100, why?

Answer 1

Because search() method will seach inside the provided string... do instead:

pattern = r"^[1-5]\d#x27;

\d is for digit (same as class [0-9])
^ at start stand for start of string
$ at end stand for end of string

Answer 2

I think you need to specify that you are only looking for 2 digits.
Something like:
pattern = r"[1-5][0-9]quot;
That way your regex will know that and end of line is expected after the second digit.
Also, I think something like this might work as well:
pattern = r"]d\dquot; - the "translation" would be : digit digit endOfLine

Answer 3

Which regex would match "[e-mail]"?
