Let’s check out some exercises that will help understand dictionaries better.
Exercise 8-a: Python Dictionary Value by Key
Dictionaries don't have index orders, so speaking about them regarding their first item or last item is not very correct. Next time you print a dictionary it may have a different order than you saw before. Instead they have keys, and we can use keys to call their values.
Exercise 8-c: Adding a List to Python Dictionary (Nested Data)
Dictionaries can have nested data too. Also, you can add a new key to a dictionary as they are mutable (changeable). Try to add the key "work" to dict with values shown below.
.items() method of Python dictionaries combines each key-value pair inside a tuple and returns a list of tuples. List consists of as many tuples as key-value pairs.
