Much like lists, tuples can also have nested elements.

Take, for instance, data about countries grouped into tuples. The indexing for nested tuples works just like it does for nested lists. That is, the first index points to an item in the main tuple, while the second index targets an item within the nested tuple. 

Let's refresh our understanding of indexing with the following example.

# Two-dimensional tuple
two_d_countries = (('USA', 9629091, 331002651), ('Canada', 9984670, 37742154), 
                   ('Germany', 357114, 83783942), ('Brazil', 8515767, 212559417), 
                   ('India', 3166391, 1380004385))

# Get information about India
print(two_d_countries[4])
# Get the area of India
print(two_d_countries[4][1])

Python is an interpreted high-level general-purpose programming language. Unlike HTML, CSS, and JavaScript, which are primarily used for web development, Python is versatile and can be used in various fields, including software development, data science, and back-end development. In this course, you'll explore the core aspects of Python, and by the end, you'll be crafting your own functions!

In this section, you'll dive into the basics of Python, familiarize yourself with your workspace, tackle simple math operations, and display your results.

Here, you'll learn how to store items like numbers and text in computer memory, recalling them by name. You'll also get a taste of text manipulation in Python.

Here, you'll delve into the boolean data type and discover its role in creating programs that respond to specific conditions.

Continuing with data types, this section will teach you how to group varied attributes within a single variable using lists, tuples, and the dictionaries.

In this part, you'll master the art of writing loops in Python – essential constructs for iterating over lists, tuples, dictionaries, and even future dataframes.

To wrap up our introductory course, you'll explore some built-in functions and then embark on creating your very own!

How can you retrieve a value from a dictionary by its key?

What is the difference between a tuple and a list?

How can you access the third element in this list?


What does the `copy()` method do for lists in Python?

Is there a strict limit on how deeply you can nest tuples/lists/dictionaries in Python?

How do you update a value in a dictionary?

How would you change "green" to "yellow"?
