Pipes module has been removed from python 3.13, resulting in ModuleNotFoundError.

[cosmicelijah]

When trying to run the grading script for heapmm lab specifically, I get a ModuleNotFoundError stating that there is no module named 'pipes'. Some googling told me that pipes was considered deprecated in python 3.0 and removed in python 3.13 (my python version is 3.13.1). The github issue post I was reading suggested replacing it with a module called shlex (Issue post: jupyter/nbclassic#308)
