Pygame 无法解决

Question

import pygame is underlined saying pygame could not be resolved.

Yet, when I launch my program, I have this message:

c:\Users\Guillaume\PycharmProjects\Learn\Snake.py pygame 2.1.2 (SDL 2.0.18, Python 3.10.2) Hello from the pygame community. https://www.pygame.org/contribute.html

And when I run python -m pip install pygame --user

WARNING: Ignoring invalid distribution -ip (c:\python310\lib\site-packages) WARNING: Ignoring invalid distribution - (c:\python310\lib\site-packages) WARNING: Ignoring invalid distribution -ip (c:\python310\lib\site-packages) WARNING: Ignoring invalid distribution - (c:\python310\lib\site-packages) Requirement already satisfied: pygame in c:\python310\lib\site-packages (2.1.2) WARNING: Ignoring invalid distribution -ip (c:\python310\lib\site-packages) WARNING: Ignoring invalid distribution - (c:\python310\lib\site-packages) WARNING: Ignoring invalid distribution -ip (c:\python310\lib\site-packages) WARNING: Ignoring invalid distribution - (c:\python310\lib\site-packages)

So it seems like pygame is working.

Though my window won't pop up, anyone?

import pygame

def drawGrid(w, rows, surface):
    sizeBtwn = w // rows

    x = 0
    y = 0
    for l in range(rows):
        x = x + sizeBtwn
        y = y + sizeBtwn

        pygame.draw.line(surface, (255,255,255), (x,0),(x,w))
        pygame.draw.line(surface, (255,255,255), (0,y),(w,y))

def redrawWindow(surface):
    global rows, width
    surface.fill((0,0,0))
    drawGrid(width,rows,surface)
    pygame.display.update()

def main():
    global rows, width
    width=500
    rows=20
    win = pygame.display.set_mode((width,width))
    flag=True

    clock=pygame.time.Clock()

    while flag:
        pygame.time.delay(50) #time
        clock.tick(10) #frame
        redrawWindow(win)

I just solved a problem. You just have to write at the bottom (outside of the def main()) main() and keep the rest as it is.

import pygame

def drawGrid(w, rows, surface):
    sizeBtwn = w // rows
    x = 0
    y = 0
    for l in range(rows):
        x = x + sizeBtwn
        y = y + sizeBtwn
        pygame.draw.line(surface, (255,255,255), (x,0),(x,w))
        pygame.draw.line(surface, (255,255,255), (0,y),(w,y))

def redrawWindow(surface):
    global rows, width
    surface.fill((0,0,0))
    drawGrid(width,rows,surface)
    pygame.display.update()

def main():
    global rows, width
    width=500
    rows=20
    win = pygame.display.set_mode((width,width))
    flag=True
    clock=pygame.time.Clock()
    while flag:
        pygame.time.delay(50) #time
        clock.tick(10) #frame
        redrawWindow(win)
main()
