for item in my_list:
    if item.find("abc") != -1:
        print item

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)

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

for item in my_list:
    if item.find("abc") != -1:
        print item

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

pattern=re.compile(r'abc') 

pattern.findall(mylist)
