Question

我已经开始自己学习python以获得乐趣，而我正在写这篇并没有得到我想要的结果：

if no1234 == 0:
     print "Player and Computer tie!\n"
elif no1234 == 1 or 2:
     print "Player wins!\n"
elif no1234 == 3 or 4:
     print "Computer wins!\n"

计算机胜利不会出现，是否有遗忘

Answer 1

elif no1234 == 1 or 2:被解析为elif (no1234 == 1) or (2):

始终为True，因为bool(2) == True并且您正在使用or声明。

你可能想要：

elif no1234 == 1 or no1234 == 2:

甚至：

elif no1234 in (1, 2):

对于您的其他elif，这是相同的。

总而言之：

if no1234 == 0:
     print "Player and Computer tie!\n"
elif no1234 in (1, 2):
     print "Player wins!\n"
elif no1234 in (3, 4):
     print "Computer wins!\n"

Answer 2

你需要这个：

if no1234 == 0:
     print "Player and Computer tie!\n"
elif no1234 == 1 or no1234 == 2:
     print "Player wins!\n"
elif no1234 == 3 or no1234 == 4:
     print "Computer wins!\n"

Python if，else语句
