Newbie here, been searching the net for hours for an answer.

string = "44-23+44*4522" # string could be longer

How do I make it a list, so the output is:

[44, 23, 44, 4522]

Using the regular expressions as suggested by AChampion, you can do the following.

string = "44-23+44*4522"
import re
result = re.findall(r'\d+',string)

The r'' signifies raw text, the '\d' find a decimal character and the + signifies 1 or more occurrences. If you expect floating points in your string that you don't want to be separated, you might what to bracket with a period '.'.

re.findall(r'[\d\.]+',string)
