Remember that if this matters to you, you can "from math import inf".
But you still need to use full eval on your repr, which could be a serious security problem in some contexts. If it were a built-in constant, ast.literal_eval could be used instead.
It is better to use float() instead of ast.literal_eval(). ast.literal_eval() is not a "safe eval", it can crash the interpreter or use enormous CPU time. It can be used to organize DOS attacks.
