LPython is a Python compiler. It is in heavy development, currently in pre-alpha stage. Some of the goals of LPython:

• The best possible performance for numerical array oriented code
• Run on all platforms
• Compile a subset of Python and be Python compatible
• Fast compilation
• Excellent user friendly diagnostic messages: error, warnings, hints, notes, etc.
• Ahead of time compilation to binaries and interactive usage (Jupyter notebook)
• Able to transform the Python code to C++, Fortran and other languages
• Explore how to design it so that it can be eventually used with any Python code

And more.
