Is Python installed on each machine or on a network server?
Rather precisely, how was Python installed?
What installation package was downloaded? From where?
How was it run?

This says that the stdlib is in the form of a zipfile instead of the
normal /lib directory. I don't know how one gets that result on
Windows. It appears that the zipped library is missing the file.

Same Python version? Same installation file? Run the same way?

We appreciate that you are trying to use current Python to teach. I
hope we are able to solve the problem, given more information.
