Installation

This library requires a functioning Python 3 environment.

Some optional visual and auditory features depend on the numpy and pygame packages.

With pip

For Python versions 3.8 - 3.10, due to compatability infeasibilities, the current safest option is to install most requirements manually before installing this package.

python3 -m pip --upgrade pip
python3 -m pip --upgrade wheel
python3 -m pip --upgrade setuptools
python3 -m pip --upgrade numpy
python3 -m pip --upgrade pygame
python3 -m pip --upgrade mypy

After the above commands execute sucessfully, install su-stdlibs-python simply with

python3 -m pip install --upgrade su-stdlibs-python

To test that you have installed the library correctly, run this command:

python3 -c 'import stdio; stdio.write("Hello World!\n")'

It should greet you. If an error message appears instead, the library is not installed correctly.

Hello World

A simple program, stored as a file hello_world.py, looks like this:

import stdio

stdio.write("Hello World!\n")

It can be run with the command python3 hello_world.py.
