This can be good and can be bad. It's good when it aids readability;
it's bad when you need to pass practically the entire locals() as
function arguments and/or return values. I would split the function
only when both halves (caller and callee) can be given short and
useful names - if you can't explain what a block of code does in a few
words, it's probably a poor choice for splitting out into a function.
