Question

我的代码如下：

a = 1
b = 2
c = 3
d = 4
e = 5
if ((a == 1 and
     b == 2 and
     c == 4) or
     (d == 4  and e == 5)):
    print "Yeah, Working"
else:
    print "ooops"

可以轻松实现同样的代码吗？

Answer 1

如果您希望条件更清晰或更好看，您可以这样做：

a = 1
b = 2
c = 3
d = 4
e = 5
if (a, b, c) == (1, 2, 4) or (d, e) == (4, 5):
    print "Yeah, Working"
else:
    print "ooops"

Answer 2

这是一个非常个人化的答案，但我喜欢在if语句之前初始化一些布尔值。我觉得它更具可读性（因为你可以为你的变量赋一些有意义的名字），而且我非常确定编译器可以很容易地对它进行优化。

cond1 = a == 1 and b == 2 and c == 4
cond2 = d == 4 and e == 5
if cond1 or cond2:
    print("Yeah, working")
else:
    print("ooops")
