If I have an input string:
a = 'W1 W2 W3 W4 W5 W6 W7 W8 W9 W10 W11'
How to extract the numbers and store in a list? For example
numList = [1,2,3,4,5,6,7,8,9,10,11]
I have tried doing it like this:
[int(t) for t in a if t.isdigit()]
This only works for the single digit numbers, but doesn't work for the double digit numbers.
You can split by space and then slice the first character of every item out:
>>> [int(item[1:]) for item in a.split()]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]
You can also, if applicable (do not know the origin and possible variations of the input string), just remove the W from the string and split:
>>> a = a.replace("W", "")
>>> [int(item) for item in a.split()]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]
You can do this with regex:
import re
numList = re.findall(r'\d+', a)
