Python regex to match a person's height-CodePudding

I am trying to create a python regex that will match a person's height, in feet and inches, separated by a single apostrophe (such as 6'0 for example). Valid heights are between 4'0 and 6'11 for my purposes: Here's what I have so far:

import re
import requests
url = 'https://rolltide.com/sports/football/roster'
re.findall('''([456][']([02-9]|1[0-1]?))''', (requests.get(url)).text)

This regex returns the following (I will just show the first few matches):

[("6'1", '1'),
 ("6'2", '2'),
 ("6'1", '1'),
 ("6'2", '2'),
 ("6'1", '1'),
 ("6'4", '4'),
 ("6'1", '1'),
 ("6'1", '1'),
 ("6'2", '2'),
 ("6'3", '3'),
 ("6'0", '0'),
 ("6'1", '1'),
 ("6'2", '2'),
 ("6'2", '2'),
 ("6'0", '0'),
 ("6'1", '1'),
 ("6'0", '0'),
 ("5'10", '10'),
 ...
 ]

I would like for the regex to return the following instead:

["6'1",
 "6'2",
 "6'1",
 "6'2",
 "6'1",
 "6'4",
 "6'1",
 "6'1",
 "6'2",
 "6'3",
 "6'0",
 "6'1",
 "6'2",
 "6'2",
 "6'0",
 "6'1",
 "6'0",
 "5'10",
 ... 
 ]

I am really not sure what the issue is. I am new to regex but I think it has to do with the parenthesis usage.

CodePudding user response：

Just use the pattern [4-6]'(?:[0-9]|1[0-1])":

import re
import requests
url = 'https://rolltide.com/sports/football/roster'
re.findall('[4-6]'(?:[0-9]|1[0-1])"', (requests.get(url)).text)

This regex pattern says to match:

[4-6]'      4-6 feet
(?:
    [0-9]   0-9 inches
    |       OR
    1[0-1]  10-11 inches
)"

Here is a demo showing that the regex is working.

CodePudding user response：

The problem is you are creating two groups, one for matching the inches alone and another for matching the whole height. That's why you are getting height and inches seperately.
