Python 字符串和子字符串

Question

I have to write a Python function that takes a list of strings as its argument. The function should then print those strings in the list that contain as substrings either "cat" or "dog".

This is the code I have but nothing comes up when I run the code in Python:

def check_string(string_list):
    for word in string_list:
       if "cat" in word or "dog" in word:
    print(word)

Answer 1

You just have some indentation issues.

def check_string(string_list):
    for word in string_list:
       if "cat" in word or "dog" in word:
            print(word)
