Bringing It All Together

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.

Storing Numbers

Using Variables

String Indexing

Negative Indexing and Length

3. Conditional Statements

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

Boolean Data Type

Challenge: Comparison Operators

Combining Conditions

Challenge: Logical Operators

Membership Operators and Types Comparison

Simple if/else Expressions

Challenge: Grocery Store

Challenge: Odd and Even

if/elif/else Expressions

Challenge: Grocery Store Extended

Challenge: Positive, Negative or Zero

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.

What Is a List?

What Is a Tuple?

What Is a Dictionary?

Dictionary Methods

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

6. Functions

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

Built-in Functions

Defining Your First Function

if/else Statements in Functions

Functions With No Return

Modifying Functions

Lambda Functions

Challenge: Grocery Store

Suppose you run a small grocery store with daily expenses of $2000. If your daily revenue is less than $2000, you're operating at a loss; otherwise, you're turning a profit. Let's craft an if/else statement to reflect this situation.

Task

Set up a conditional statement to determine if the revenue variable is below 2000.

If it is, display the message "We're operating at a loss!".
Otherwise, display the message "Everything is good!".

Please refrain from altering the revenue value.
