Now that you have parsed Python code, you can do some necessary processing first, output it as Python code again and use an existing implementation of the Python language for execution. | 3 | 0 | 0 | I am currently using a Python 2.5 sample from the ANTLR website. I'm actually wondering if the grammar already produces semantics as well.If there is none, what can I do or what can I use(tools) for generating semantics for python after parsing it with ANTLR? | Does ANTLR provide semantics | 1.2 | 0 | 0 | 121 |

If you added semantics, you'd have a full python implementation (modulo fleshing out the libraries). | 3 | 0 | 0 | I am currently using a Python 2.5 sample from the ANTLR website.

Also their is Cython, which converts a form-of-Python to C, so that may provide another more direct path by combining the two with C as the glue, and without SWIG.
I was told... | 1 | 2 | 0 | Can SWIG be used to call Go functions from Python?
The Go examples I have seen in SWIG all seem to call C/C++ functions from Go. | SWIG: Calling Go from Python | 0.197375 | 0 | 0 | 754 |

I am writing a simulation engine in python using "threading" module in python. One of the things that my simulator has to do is to be able to do all-to-all communication. Suppose there are 'n' threads (All n-threads are not instances of the same class).

Alternatively you could link those threads to form a cycle and pass message to the suc... | 2 | 1 | 0 | Thanks for your attention
