# Pyodide Python compatibility
|
||
|
|
|
||
|
|
|
||
|
|
## Python Standard library
|
||
|
|
|
||
|
|
Most of the Python standard library is functional, except for the modules
|
||
|
|
listed in the sections below. A large part of the CPython test suite passes except for
|
||
|
|
tests skipped in
|
||
|
|
[`src/tests/python_tests.txt`](https://github.com/pyodide/pyodide/blob/main/src/tests/python_tests.txt)
|
||
|
|
or via [patches](https://github.com/pyodide/pyodide/tree/main/cpython/patches).
|
||
|
|
|
||
|
|
### Optional modules
|
||
|
|
|
||
|
|
The following stdlib modules are included by default, however
|
||
|
|
they can be excluded with `loadPyodide({..., fullStdLib = false })`.
|
||
|
|
Individual modules can then be loaded as necessary using
|
||
|
|
{any}`pyodide.loadPackage`,
|
||
|
|
|
||
|
|
- distutils
|
||
|
|
- test: it is an exception to the above, since it is excluded by default.
|
||
|
|
|
||
|
|
### Removed modules
|
||
|
|
|
||
|
|
The following modules are removed from the standard library to reduce download size and
|
||
|
|
since they currently wouldn't work in the WebAssembly VM,
|
||
|
|
|
||
|
|
- ctypes
|
||
|
|
- curses
|
||
|
|
- dbm
|
||
|
|
- ensurepip
|
||
|
|
- idlelib
|
||
|
|
- lib2to3
|
||
|
|
- tkinter
|
||
|
|
- turtle.py
|
||
|
|
- turtledemo
|
||
|
|
- venv
|
||
|
|
- webbrowser.py
|
||
|
|
|
||
|
|
### Included but not working modules
|
||
|
|
|
||
|
|
The following modules can be imported, but are not functional due to the limitations of the WebAssembly VM:
|
||
|
|
- multiprocessing
|
||
|
|
- threading
|
||
|
|
- sockets
|
||
|
|
|
||
|
|
as well as any functionality that requires these.
