Extract or split a string or number to be in an array for print format

i tried using the split function. it works fine. but the problem is my string doesn’t have a separator that I can define.
for example, this string “123456789” i would like to be able to extract each number.

list1[0] = 1
list1[1] = 2

list1[8] = 9

thank you!

found a work around. used slice notation. thanks!
