any('abc' in item for item in mylist)

mylist=['abc','def','ghi','abc']

pattern=re.compile(r'abc') 

pattern.findall(mylist)

any('abc' in item for item in mylist)

只是抛出这个：如果你恰好需要匹配多个字符串，例如abc和def，你可以按如下方式组合两个理解：

matchers = ['abc','def']
matching = [s for s in my_list if any(xs in s for xs in matchers)]

输出：

['abc-123', 'def-456', 'abc-456']

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)

def find_dog(new_ls):
    splt = new_ls.split()
    if 'dog' in splt:
        print("True")
    else:
        print('False')


find_dog("Is there a dog here?")
