To check that these Python modules are ready to go, enter into your local Python 3 programming environment or server-based programming environment and start the Python interpreter in your command line like so: python Copy From within the interpreter you can run theimportstatement to make sure tha...
You can then unpickle the pickled string in another variable, restoring an exact copy of the previously pickled class: Python # pickling.py import pickle class example_class: a_number = 35 a_string = "hey" a_list = [1, 2, 3] a_dict = {"first": "a", "second": 2, "third":...
