Check to see if text is contained within a variable in a list in Python

I am working with this code:

test_list = ['small_cat', 'big_dog', 'turtle']

if 'dog' not in test_list:
    output = 'Good'
else:
    output = 'Bad'

print (Output) 

Because ‘dog’ is not in the list, ‘output’ will come back with a response of ‘Good’. However, I am looking for ‘output’ to return ‘Bad’ because the word ‘dog’ is part of an item in the list. How would I go about doing this?

>Solution :

You should iterate all the values in test_list –

output = 'Good'
for test_word in test_list:
    if 'dog' in test_word:
        output = 'Bad'
        break

print(output)
