Problem: correlation

Lab 2 snekoban

Problem 0: why assertion in test fails while it can run correctly in the GUI?

Answer: do not modify the input game.

time: stuck for one hour

where (goes wrong): Figured out in assertionErrors in vscode: somehow the pytest in pycharm lost the critical information: modify the input game type

Experiment 1: disable the assertions for checking modifications

Result: passed all the basic tests.

Experiment 2: is dict deep copied?

Result: no. It turns out that dict(some_dict) or some_dict.copy() is shallow copy. Deep copy should use copy.deepcopy(some_dict) or be a lamb :) to copy every element in the dict.

Thus it solves the problem.
