Question

我有两个文件：sprites.py和test.py。在sprites.py中，我创建了一个Player课程。我使用main将所有内容导入test.py文件（from player import *）。

sprites.py：

import pygame
from test import *

class Player(pygame.sprite.Sprite):
    # ...
    pass

test.py：

import pygame
from sprites import *

# ...

all_sprites = pygame.sprite.Group()
player = Player()                       #  <-- line 28, NameError
all_sprites.add(player)

我收到此错误：

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    from sprites import *
  File "C:\Users\Adam\Desktop\PYthon Test\sprites.py", line 2, in <module>
    from test import *
  File "C:\Users\Adam\Desktop\PYthon Test\test.py", line 28, in <module>
    player = Player()
NameError: name 'Player' is not defined

我已经确保我拼写正确的一切。这个错误可能来自哪里？

Answer 1

public class Car { [HiddenInput(DisplayValue = false)] public int CarID { get; set; } public string ModelName { get; set; } public int ManufacturerID { get; set; } public int Year { get; set; } public decimal Mpg { get; set; } }中的问题是from test import * - 有循环导入有时会产生问题

我的版本有一些其他修改。
