I would like to ask where the Python source code of the Transform module is, and I want to learn it.

I think this is the code of the transforms module:

Here you have two links that may be useful for you:

Just to clarify, Transforms module is implemented in C++ and Python-wrapped to make it available in Python. Most core modules and low-level features, processing, and GUI widgets are implemented in C++.
