Download this code from https://codegive.com Certainly! In Python, dictionaries are versatile data structures that store key-value pairs. Reading values from a dictionary is a fundamental operation, and in this tutorial, I'll guide you through the process with code examples. A dictionary in Python is defined using curly braces {}. Each key-value pair is separated by a colon :. To read a value from a dictionary, you can use the key enclosed in square brackets []. Before accessing a key in a dictionary, it's good practice to check if the key exists using the in keyword. The get method is another way to retrieve a value from a dictionary. It allows you to specify a default value if the key is not found. You can iterate through the keys or values of a dictionary using the keys() and values() methods, respectively. If you want to iterate through both keys and values simultaneously, you can use the items() method. Reading values from a dictionary in Python is a straightforward process. Whether you use square brackets, the get method, or various iteration techniques, understanding these methods will empower you to work effectively with dictionaries in your Python programs. ChatGPT
