trying to recall a regex for re.split()

[Skaperen]

remember that parentheses indicate what you want to recover

when do i use parenthesis if i am doing re.split()? why are you using re.search()?

if i don't use re, then the way i would do this is a loop through each character and trying it, alone, in int(ch,10) or .isdigit() or .isdecimal(), then splicing up to, and from, that position where the loop breaks.
