When I attempt to run some test code my professor gave me using Python3.7 on Linux Mint 19 I get the following error

RuntimeError: Bad code object in .pyc file
Error in sys.excepthook:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 63, in apport_excepthook

    import apt
  File "/usr/lib/python3/dist-packages/apt/__init__.py", line 23, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

Original exception was:
RuntimeError: Bad code object in .pyc file

At first, I only installed Python3.7 minimal and this error didn't occur, but I needed to install the full version of Python3.7 to use some modules that come with it, and that started this error. I already tried installing Python3.7 dev and it did nothing. I also tried

sudo apt-get remove --purge python3.7-apt

and it said it couldn't even find apt. So I tried 

sudo apt-get install python3.7-apt

and it couldn't even find the package. I also tried installing python3-apt and it did nothing. I would uninstall python3-apt first but apparently that could harm the OS because Mint uses Python3.6 internally. Any help resolving this would be much appreciated!
