Antoine Pitrou added the comment:

The whole example is bad and should be removed or replace with something else:

1. Using map() is an anti-pattern here, since the function results are not used.

2. To "build a dictionary that maps the ordinals from 0 to 255 to their character equivalents", modern Python code should use a dict comprehension and avoid operator.setitem() entirely.
