How are the executables in <python_dir>\python-X.X.X\scripts created?

Question

When I install a package via pip (on Windows), e.g. pip, one or more Windows executables are created in the scripts directory.

> PowerShell -NoProfile -ExecutionPolicy -Command "Invoke-WebRequest -Uri 'https://bootstrap.pypa.io/get-pip.py' -OutFile 'get-pip.py'" 
> python get-pip.py

pip.exe, pip3.exe, and pip3.8.exe all look to be something kind of py2exe-ish with a Python script embedded in the executable.

What is auto-creating these executables?

The embedded script uses a shebang that has a hardcoded path to the python executable. What I intend as a portable Python distribution is being hosed by this hardcoded path (rather than just specifying python without a path).

Details which may or may not matter

WinPython 3.8.5 x86
Windows 10 x64

Is there a way to tell pip (or whatever is creating these wrapped executables) to behave differently in this regard?

Your question is not clear, do you want to make portable your python interpreter with its packages and executables — Faizan AlHassan

I have a portable installation. I update packages with pip. It's no longer portable. I want to be able able to update/install packages and keep it portable. — mojo

The question remains that I want to control the generation of these executables (or at least know who/how they're being generated). — mojo

If you want your packages to be installed for a specific python version, you can install that using: your\particular\python -m pip install some_package — Faizan AlHassan

The version is not the issue. It's the "location" of python that creates problems. The absolute path to python.exe is hardcoded into script embedded in the .exe. Where's the exe coming from? That's (the beginning) of the answer to my question. — mojo

These files are created using py2exe whose configurations can be found in setup.py file of the project.
