In Python, functions can return multiple values using various techniques. This tutorial will guide you through different methods of returning multiple values from a function with code examples.
In this example, the return_tuple function returns a tuple containing three values. You can unpack the tuple into individual variables or use it as a whole.
Instead of returning a tuple, you can also return a list containing the desired values. The usage is similar to returning a tuple.
Namedtuples provide a convenient way to return multiple values with named fields. It combines the readability of dictionaries with the immutability of tuples.
Functions can also return a dictionary with named keys corresponding to the values. This method is flexible and allows you to access values using keys.
You can directly unpack values in the return statement. This approach is concise and readable, especially when you know the order of the returned values.
Choose the method that best fits your needs and the requirements of your program. Each approach has its advantages, so consider factors like readability, immutability, and ease of use when deciding which method to employ.

In Python, a function can return multiple values by packing them into a tuple, list, or other iterable data structures. This allows you to conveniently return and unpack multiple values from a function. In this tutorial, we'll explore different ways to achieve this with code examples.
In this example, the get_user_info function returns a tuple containing three values - name, age, and email. When calling the function, we can unpack the tuple into separate variables.
Here, the get_student_details function returns a list with name, age, and grades. Similar to the tuple example, we can unpack the list into separate variables.
In this example, we use a named tuple (Person) to define a structure for the returned values. The function returns an instance of the named tuple, and we can access the values using named attributes.
Returning multiple values in Python is a powerful feature that allows functions to provide more information in a structured way. Whether using tuples, lists, or named tuples, choose the approach that best fits your needs. Remember to document your function's return values to make it clear to users how to use the returned data.
