如何在以下列表中搜索包含字符串“abc”的项目?

xs = ['abc-123', 'def-456', 'ghi-789', 'abc-456']

以下检查“abc”是否在列表中,但未检测到“abc-123”和“abc-456”:

if 'abc' in xs:

当前回答

使用筛选器获取具有“abc”的所有元素:

>>> xs = ['abc-123', 'def-456', 'ghi-789', 'abc-456']
>>> list(filter(lambda x: 'abc' in x, xs))
['abc-123', 'abc-456']

还可以使用列表理解:

>>> [x for x in xs if 'abc' in x]

其他回答

x = 'aaa'
L = ['aaa-12', 'bbbaaa', 'cccaa']
res = [y for y in L if x in y]

要检查列表中任何字符串中是否存在“abc”,请执行以下操作:

xs = ['abc-123', 'def-456', 'ghi-789', 'abc-456']

if any("abc" in s for s in xs):
    ...

要获取包含“abc”的所有项目:

matching = [s for s in xs if "abc" in s]

我需要与以下匹配项对应的列表索引:

lst=['abc-123', 'def-456', 'ghi-789', 'abc-456']

[n for n, x in enumerate(lst) if 'abc' in x]

输出

[0, 3]
any('abc' in item for item in mylist)

我是Python新手。我得到了下面的代码,使其易于理解:

my_list = ['abc-123', 'def-456', 'ghi-789', 'abc-456']
for item in my_list:
    if 'abc' in item:
       print(item)
