Python is just one example, a lot of applications need entropy. i disagree that this is a good solution; similar to your haveged suggestion, this is a workaround. Unless a program specifically uses randomness, it should not need to read any entropy. For the python runtime itself, this is preventable by setting fixed PYTHONHASHSEED. For `random` module, there is no clean way to prevent it.
