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
or via 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
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,
curses
dbm
ensurepip
idlelib
lib2to3
tkinter
turtle.py
turtledemo
venv
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.
