It is not necessary to use the initial cast since
(char *)f->f_code->co_filename + 20
is already a `char *'.

Not really. What this expression does it actually somewhat
complicated. For example, suppose X is some object in the python
language, e.g.,
X = 3.0
How would you form a string from the last 3 bytes of the 8 byte object
represented by X in pure python? In C you would use `(char *)&X + 5'.
Why you would want to do this another issue.
