使用或在Python中使用if语句短

Question

我有if声明

if "1111111" in players or "0000000" in players or "blablabla" in players:
    do something

如何简写？

Answer 1

您可以使用any()：

things = ["1111111", "0000000", "blablabla"]

if any(thing in players for thing in things):

Answer 2

if any(x in players for x in ("1111111", "0000000", "blablabla")):
    # do something

如果您要进行大量这些成员资格检查，您可以考虑将players变为set，而{{1}}不需要在每次检查时遍历整个序列。

Answer 3

if any(a in players for a in list_of_tests):
   #something
   pass

如果您使用numpy.any()，则需要先将生成器转换为列表。

if np.any([a in players for a in list_of_tests]):
   #something
   pass
