Keep in mind that the `range()` function needs at least one argument. Since indexing in Python begins at `0`, you can use the **length of the sequence** as the sole argument for the `range()` function.

To determine the length of a sequence, employ the `len()` function. For example, you can loop through the list from earlier sections, but this time by its indices.

# Initial list
values = [1, [2, 3], 4, "code"]

# Initialize a for loop over indexes
for i in range(len(values)):
  print("Index:", i)
  print("Value:", values[i])
  print("----") # Delimiter

At each iteration of the loop, the variable `i` **sequentially traverses the indices** of `values`, ranging from `0` to `3`.

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!
