while True:

    screen.blit(player_image, player_location)

    if player_location[1] > WINDOW_SIZE[1]-player_image.get_height: #line 27
        player_y_momentum = -player_y_momentum
    else:
        player_y_momentum += 0.2

    if moving_right == True:
        player_location[0] += 4
    if moving_left == True:

Answer 1

我从未使用过pygame，但我认为您可以通过将第27行更改为：

if player_location[1] > WINDOW_SIZE[1]-player_image.get_height(): #line 27

我假设get_height（）是一个函数，而不是player_image对象的元素，因此应该附上括号。

此外，由于您在此处执行减法运算，因此两个元素都应为数字。由于

player_image.get_height

不会返回数值，您将得到不支持的操作数类型错误。

Answer 2

将此player_image.get_height更改为player_image.get_height()。您指的是函数，而不是获取函数的返回值。

继续在第27行出现错误：TypeError：-：'int'和'builtin_function_or_method'不受支持的操作数类型
