Fix getting python install path

[nater1983]

Get Python Paths Using the python.get_path() Method:

Retrieve specific paths like purelib and stdlib using python.get_path().

Handle Paths Manually:

Construct the paths based on the information provided by the python.get_path() method.

python_bin.get_path('purelib'): This retrieves the directory where Python packages are installed. python_bin.get_path('stdlib'): This retrieves the directory for Python standard libraries.
