Dictionaries are used to store data values in key:value pairs. A dictionary is a collection which is ordered*, changeable and do not allow duplicates. As of Python version 3.7, dictionaries are ordered. In Python 3.6 and earlier, dictionaries are unordered. Dictionaries are written with curly brackets, and have keys and values:

What is a Python Dictionary? A Python dictionary is a collection of key-value pairs where each key must be unique. Think of it like a real-world dictionary where each word (key) has a definition (value). Dictionaries are: Unordered (in Python versions before 3.7) Ordered (from Python 3.7 onwards) Mutable (can be changed) Indexed by keys, not ...

Python dictionaries are a data type that allows for the storage and retrieval of key-value pairs. They are useful because they provide an efficient way to access and modify data, allowing for quick and easy data manipulation.

Use the for loop to iterate a dictionary in the Python script. print("Key = " + key + ", Value = " + capitals[key]) As mentioned earlier, the key cannot appear more than once. Use the same key and assign a new value to it to update the dictionary object.
