dictionary in python iteration

Dictionaries in Python are powerful data structures that allow you to store and retrieve key-value pairs efficiently. Iterating through dictionaries is a common operation, and Python provides several ways to achieve this. In this tutorial, we will explore different methods to iterate through dictionaries with code examples.
Both methods above produce the same result. The keys() method explicitly returns a view object containing all the keys in the dictionary, while the second method implicitly iterates through the keys.
The values() method returns a view object containing all the values in the dictionary. Alternatively, you can iterate through the keys and retrieve the corresponding values.
The items() method returns a view object containing tuples of key-value pairs. You can also iterate through the keys and use them to retrieve the corresponding values.
Dictionary comprehension allows you to create a new dictionary by specifying the key-value pairs based on an expression. In this example, we square each value in the original dictionary.
Iterating through dictionaries in Python is a fundamental skill. Depending on your needs, you can choose the method that suits your code style and requirements. The keys(), values(), and items() methods, along with dictionary comprehension, provide flexible options for iterating through dictionaries efficiently.
