pytogo is a fast, crude, incomplete Python-to-Go translator meant to assist a human programmer in translating large volumes of Python to idiomatic Go, preserving comments and structure. It does the mechanical things that are easy for software but hard for humans, leaving a human free to concentrate on the hard parts like type annotations.

It exists because at the time it was written the only automated translators available either produced rather horrifying generated Go or wouldn’t translate standalone Python code to standalone Go.

It is conservative, never actually throwing away information from the input Python. It assumes its Python input is well-formed, and can fail on inputs that are sufficiently weird.

People using this tool might also want to know about these projects:


Much of Python’s difflib ported to Go.

Python getopt ported to Go.


Python Cmd ported to Go.

Readline workalike that can be used to translate Python raw_input().
