Where does Sys path come from?

sys. path is a built-in variable within the sys module. It contains a list of directories that the interpreter will search in for the required module. When a module(a module is a python file) is imported within a Python file, the interpreter first searches for the specified module among its built-in modules.

How does Sys path work?

Is the pythonpath the same as sys.path?

This is the result of sys.path. However sys.path is not the environment variable PYTHONPATH. If you set the PYTHONPATH in your system, then all the path contained in it will be included in the array that python’s interpreter uses to search for modules.

Can a Python module be touched by sys.path?

Library modules should certainly not be touching sys.path themselves. Instead, you’d normally have a hashbanged-script outside the package that you use to instantiate and run the app, and it’s in this trivial wrapper script you’d put deployment details like sys.path -frobbing.

Where does the PATH variable in Python Go?

For instance the sys and os modules are built-in modules. That’s it really. 2) The PYTHONPATH variable don’t exist by default on your system. When you launch the python interpreter, it fills the array of path where it search for modules, in the way you described. This is the result of sys.path.
