Extract a number from a string anytime after a certain character using Python regex [duplicate]
This question already has an answer here:
match string after the last colon
3 answers
I have the following string:
"(rating 1-10, details): 9 is my score"
I want to extract all numbers into a list that occur after :. The desired output is [9]
Assumptions
-Only one colon in expression
-0 or more values after the colon
-text before the colon may or may not contain numbers
-characters between colon and numbers may or may not be just spaces
I tried using this REGEX expression in Python:
':*(d+)'
My logic here is that the program should find the colon and then find digits an undetermined number of characters later. I am not sure how to handle the number of characters between the colon and the number, which varies. How do I do this?

You can use this regex and find all numbers, that appear after colon in your string.
d+(?!.*:)
Explanation:
d+--> Matches one or more digits(?!.*:)--> Negative look aheads to ensures colon does not appear ahead of numbers where we are not interested to capture
Demo
Here is a sample python code,
import re
s = '(rating 1-10, 56 details): 9 is my 22 jj 45 score'
numbers = re.findall('d+(?!.*:)', s)
print(numbers)
This prints following output,
['9', '22', '45']
And does not capture 1, 10 and 56 as they occur before colon.
