GoPy

GoPy is an experimental Python interpreter implementation in Go. It parses produced Python bytecode and executes it.

The following python code (see src/main/testapps/example.py)...

import time

def hello(name, counter):
    print "Hello", name, counter, "!"    

a = 5
b = 10
print a, "*", b, "=", a*b
print "Unix time?", time.time()	

i = 0
while i < 5:
	hello("Go", i)
	i += 1

... would be executed as ...

I created GoPy to get in touch with the Go language and learn its basics. It's currently not more than an experimental approach and has some bugs which must be fixed in order to get more complicated programs running.
