I would like to split M22 (so split the string M and the number 22)
I tried finding help from the internet, but most solutions are too complicated too begin with.
If it's always : 1 letter 2 digit, just slice the string
v = "M22"
letter, digits = v[0], v[1:]
print(letter, digits) # M 22
If the amount of each is variable, use a regex
import re
v = "M22"
letter, digits = re.search("([A-Z]+)(\d+)", v).groups()
print(letter, digits) # M 22
