另一种选择

>>> a = ['red', 'blue', 'green', 'red']
>>> b = 'red'
>>> offset = 0;
>>> indices = list()
>>> for i in range(a.count(b)):
...     indices.append(a.index(b,offset))
...     offset = indices[-1]+1
... 
>>> indices
[0, 3]
>>> 

me = ["foo", "bar", "baz"]
me.index("bar") 

您可以将此应用于列表中的任何成员以获取其索引

简单地说，你可以

a = [['hand', 'head'], ['phone', 'wallet'], ['lost', 'stock']]
b = ['phone', 'lost']

res = [[x[0] for x in a].index(y) for y in b]

所有具有zip函数的索引：

get_indexes = lambda x, xs: [i for (y, i) in zip(xs, range(len(xs))) if x == y]

print get_indexes(2, [1, 2, 3, 4, 5, 6, 3, 2, 3, 2])
print get_indexes('f', 'xsfhhttytffsafweef')

在查找列表中项目的索引时，列表理解将是获得紧凑实现的最佳选择。

a_list = ["a", "b", "a"]
print([index for (index , item) in enumerate(a_list) if item == "a"])

a = ["foo","bar","baz",'bar','any','much']

indexes = [index for index in range(len(a)) if a[index] == 'bar']
