In the "string" module, there's a function called "string.split"
that does this same thing. The Python libraries are vast deep
repositories of boundless ingenuity:

Instead of writing "string_to_chip[index:index+1]", you can just write
"string_to_chop[index]". Two lines later you write "last_space = index + 1"
which suggests that you expect the tokens on the line to always be
separated by exactly one space; otherwise you'll end up with confusing
results. Try tokenize("abc     def     ghi") and see what it does.
