pygor

Python to Go Regurgitator

Dr. Frederick Frankenstein: You must be Igor. [he pronounces it ee-gor.]
Igor: No, it's pronounced "eye-gor."

A Python 3 to Go transpiler, with many things to be desired. The purpose of this tool is not to do a complete working translation from Python to Go, but to do a good first pass into "readable" Go. But there is some effort to convert some "pythonism" into working Go (list/dict comprehension, generators, etc.) and to convert common library calls to Go equivalents.

Note that the parser is currently targeted to Python 3.4 so some latest Python 3 additions are not supported (yet) and are reported as parsing errors.

example

original

def test():
    a = 1
    if a < 5:
        return a + 5
    return a - 5

def one():
    n = 5

    def two():
        print(n + 3)

    print(two())

converted

import "fmt"

func test() {
        var a = 1
        if a < 5 {
                return a + 5
        }
        return a - 5
} 

func one() {
        var n = 5
        two := func() {
                fmt.Println(n + 3)
        }

        fmt.Println(two())
}
