🎓 Welcome back to Digital Academy, the Complete Python Development Tutorial for Beginners, which will help you Learn Python from A to Z!

🖥️ Check if Item Exists in a Dictionary in Python (IN, NOT IN)

If you want to know if a key or values exists inside a dictionary, use the “in” and “not in” Operators in Python, combined with IF statements.

○ Check if Key inside Dictionary

You can use keys() method, to check whether your key is part of the dictionary’s keys.

     my_dict = {
          'age': 27,
          'job': 'Youtuber',
          'name': 'Digital Academy'
     }
     
     print('name' in my_dict)          # True
     print('salary' in my_dict)        # False
     print('name' in my_dict.keys())   # True

○ Check if Value inside Dictionary

On the other hand, to check whether a certain value exists inside a dictionary, you must use the “in” operator combined with the values() method.

     my_dict = {
          'age': 27,
          'job': 'Youtuber',
          'name': 'Digital Academy'
     }
     
     print('Digital Academy' in my_dict.values())      # True
     print('Jérémy' in my_dict.values())               # False
