Getting started (2 minutes)
You will need Python 3 to run the translator. Refer to your operating system documentation to know how to do it (most Linux distributions have Python 3 readily available).
Then you can use pip to install the stable translator:
pip install pythonium
The above package installs a pythonium command that has the following options:
Usage:pythonium [-h][-d][-r][-V][FILE ...] [-o FILE]|[-g]
What? (2 minutes)
Pythonium will exist in two flavors, each with their own strengths and performance characteristics. As you go down the list the more features you’ll have, and performance will, of course, decrease with sophistication (but not much):
- Pythonium Veloce
- Fully portable
- Exact same syntax as Python 3
- Automatic scope handling and global support
- Anonymous exceptions with __exception__ special variable
- Support of yield
- print is translated to console.log
- if __DOLLAR__ is found in any name, it will be replaced by $ character.
- Support of from ... import ... via requirejs
- Support of single inheritance classes via classy 
Also there is cookbook.
- Pythonium Compliant 100% compliant with CPython 3
Why? (3 minutes)
Is 100% compliance of any interest right now? Do you need to build anything that uses all the features of CPython right now? No.
Can you trade some features for speed? Yes.
For the industry, experienced programmers, and hobbyists, the best approach is to have something tailored to get things done in the browser with the syntax they prefer.
