'if/else语句评估中的名称错误'

Question

我的代码如下：

else:
print("that is incorrect!")
choice = input("Would you like to (g)uess again, or (q)uit? ")
if choice == "g":
    guess == input("What animal is this? ")
elif choice == "q":
    game_running = False
else:
    print("That is not a valid option")
    choice = input("Would you like to (g)uess again, or (q)uit? ")

当我运行它时，它为input=g、q或其他任何值返回以下值。在

^{pr2}$

我以前曾多次使用这种评估用户猜测的格式，从未遇到过任何问题。如有任何建议，我们将不胜感激！我在macosx上运行pygame，并将python设置为python3，以使pygame能够更有效地工作。我补充道：

from __future__ import division, absolute_import, print_function, unicode_literals

使python能够使用python3功能。在

有两个问题，一个是else，另一个我认为是：guess==input（“这是什么动物？”）。跟着下面的零钱走！在

else:
    print("that is incorrect!")
choice = input("Would you like to (g)uess again, or (q)uit? ")
if choice == "g":
    guess = input("What animal is this? ")
elif choice == "q":
    game_running = False
else:
    print("That is not a valid option")
    choice = input("Would you like to (g)uess again, or (q)uit? ")
