So, I’ve been trying to come up with a solution to pass parameters with my functions housed in a dictionary. It turns out the answer could be in the functools package. My quest to solve one of my problems has led me straight to another:
PS C:\Users\nmalo\documents\coding\Python\LPTHW\projects\gorthonweb\gorthonweb> pip install functools
Collecting functools

Complete output from command python setup.py egg_info:

I’ve checked out GitHub and Stack Overflow, and it seems as though there isn’t actually a consensus on how to fix this - but it does appear to be a problem specific to python 3.7. I’ve tried updating my setuptoops package to the most recent version, but that didn’t do the trick. Other people are recommending I download other packages that can act as facilitators, but I’d rather not jump down this rabbit hole of installing packages in vain if I don’t have to.
I don’t have a solution to this, but is your Python installed in your main system or in a virtual environment?
Also, out of curiosity, what do you mean by passing parameters with functions housed in a dictionary? You mean that the dict values are function definitions and the keys are the function names? What kind of args/parameters would require functools? Can you post a sample?
I also believe I used some of this in a few of the LCLive videos, but I might be able to cover this module on Saturday when I do the next class. It could be a good topic and it does solve a few things in the oop code I was working on.
Honestly, it could be worse: I only spent a few hours looking into it. And it’s a really good thing that the folks at python included it in 3.7. I was getting so many different answers on all the Stack Overflow threads I looked at. Also, it would have been nice if pip would have just told me I had already satisfied the requirement.
@austenThis is a good example of what I’m trying to do, in a way. I’m making a combat system for our web-based game, and I don’t want it to be a bunch of if-statements because that isn’t going to be compatible with the forms I’ll be working with in my template and app.
player_choice = str(input("It's your turn! > "))
player.moves.do(player_choice)
So, I’m using this to grab the function call from my dictionary - like this one:
def basic_attack(self, enemy, block):
pass
Only, in the dictionary, I can’t pass these parameters. It’s just going to say they’re undefined. But I also can’t include the function call without the parameters because it’s going to say I’m missing positional arguments.
Here’s another thread I found on the partial class found in the functools package.
Man, you are soooo close to implementing OOP the way Python does it. Did you go through my OOPSchool code and the videos? If you did that, and then used functools to attach the self/dict from my oop.py code, you’d mostly have python’s oop. Just a thought dropped in your head.
I watched OOPSchool 1, but I made the mistake of doing so at like 11:00 at night. I’ll be watching that again.
Honestly, I could use a break from working on this exercise. And I really need to start watching these seminars. I’ll check them out. I’m always aiming for comprehension, and it’s an added bonus If I can apply it to this exercise.
