If 语句的缩进错误

Question

if mssge <= answr:
    print("Too High, Try Again")
elif mssge >= answr:
    print("Too Low, Try Again")
else:
    print("Nice Job! R to play again; Q to quit")

    if event.type == pygame.Q:
            sys.exit()

    else event.type == pygame.R:
            break
            gotoline(7)

我制作游戏已经有一段时间了，但我才刚刚开始 python。我正在无聊地制作一个数字猜谜游戏，但我总是在第 17 行或 if 语句的最后一个 else 上收到缩进错误。

Answer 1

else 语句中不能有条件。 Else 应该捕获所有 而不是 被前面的 if/elifs.

捕获的情况

您的第一个代码块应该是

if message_1 <= rand_numb:
    print("Too High, Try Again")
elif message_1 >= rand_numb:
    print("Too Low, Try Again")
else:  # <------ no conditions here!
    print("Nice Job! R to play again; Q to quit")

if event.type == pygame.Q:
    sys.exit()

else event.type == pygame.R:
    gotoline(5)
    break

Answer 2

else 子句不带条件。您可以将其写成 elif 子句，也可以直接写成 else. 注意，顺便说一句，您应该从前两个条件中删除 = 以使代码正确：

if message_1 < rand_numb:
    # <= replaced with < in this condition ^
    print("Too High, Try Again")
elif message_1 > rand_numb:
    print("Too Low, Try Again")
    # >= replaced with > in this condition ^
else:
    # No condition on else ^
    print("Nice Job! R to play again; Q to quit")
