Introduction to Python

1. First Acquaintance

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

2. Variables and Types

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.

Negative Indexing and Length

Concatenation

3. Conditional Statements

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

4. Other Data Types

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

5. Loops

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.

Iterating Over Indexes

Nested Loops

6. Functions

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

Tuple Methods

Let's dive into the primary methods associated with tuples.

len(t) - gives the number of elements in the tuple t;
t * n - produces n repetitions of the tuple t;
t.count(x) - counts how often x appears in the tuple t.

In the previous chapter, we highlighted that tuples are immutable. So, you might wonder: "How can I update a tuple with new values?"

Unlike lists, you can't use methods like .append() or .extend() with tuples. However, remember a few chapters back when we discussed concatenation? Here's the method that works for tuples too:

tuple1 + tuple2 - this joins two tuples together (both elements must be tuples).

For instance, let's add some new data to the tuple we were working with in the last example.

Just a heads up: make sure the data you're adding is also in tuple format to successfully concatenate.
