How can I assign p arguments when there are two non-terminals side by side (PLY) about ply HOT 7 CLOSED

Regrettably, I'm not able to help with course assignments or projects that happen to use PLY. For the specific issue at hand in this bug report, if you want to return multiple things from a grammar rule, you need to use some kind of container (list, tuple, etc.) and assign that to p[0].

I'd look at Crafting Interpreters (https://craftinginterpreters.com).

It doesn't work?

Yes but there are two problems in the code. I'm not sure if the above code works properly because I can't test it. To tell about main issue takes long time and I can't write all of that in a comment line, so, let me share with you the link of the question in stack overflow where I describe what is the problem.

First of all, thank you for your immediate attention. If I hadn't tried every way I could think of, I wouldn't have asked you for help for my project. About other Issue, I got that the code shown above is correct for assingment. Did you mean it?

If you're assigning multiple values to p[0], you need to use a tuple or list:

p[0] = (p[1], p[2])

or something similar.

Thanks a lot. Are there any examples for AST construction that I can study on?
