你能在 python 中“嵌套”模块吗？

Question

I'm working with a pygame tutorial and I'm importing the pygame module on a separate file from my main.py.

pygame.py:

    import pygame

class Game:

    def __init__(self):

main.py:

from game import Game

def main():

I'm guessing I already have my answer, since I keep receiving the error: "NameError: name 'pygame' is not defined", but is there any way to nest modules without importing them into your main? Not a big deal, just thought I'd ask.

Answer 1

You might access imported modules inside imported modules following way

mymodule.py

import math
class Math:
    pass

main.py

import mymodule
print(mymodule.math.cos(0.0))

then running python main.py output
