Separate digits from text in Python

Question

I'm trying to separate numbers from a string in Python such as this example:

text = "Compute the average of 5,7". (I want to get a list [5,7])

(the comma between the numbers is a must) I've tried using:

numbers = [int(i) for i in text.split() if i.isdigit()]

It works when the numbers aren't separated by the comma but when written with a comma I just receive an empty list.

Answer 1

Use a regular expression to find two integers separated by comma.

import re

m = re.search(r'(\d+),(\d+)', text)
if m:
    numbers = [int(x) for x in m.groups()]

Answer 2

Try this:

text = "Compute the average of 5,7"
nums = [int(i) for i in text if i.isdigit()]
print(nums)
# prints [5, 7]

Answer 3

>>> import re
>>> re.search('.*(\d,\d).*', text).group(1)
'5,7'
