Topic: Understanding strings, integers, floats, booleans

Code prompt: name = "Jake" age = 30 is_consultant = True print(f"{name} is {age} years old. Consultant: {is_consultant}")

Details: Practice declaring variables and printing their values.

Variables:

In Python, a variable is a name that refers to a value stored in memory. You can think of it as a label for data. Variables allow you to store, retrieve, and manipulate data throughout your program.

You can declare them use the ‘=’ operator:

example_variable = my_variable

Key Points:

• You don’t need to declare the type of a variable explicitly; Python is dynamically typed (so it does that work for you).
• Variable names should be descriptive, start with a letter or underscore, and not contain spaces.
• You can reassign variables to different types, by repeating the declare step:

x = 10 # intege x = "ten" # now a string

Data types:

There are a few data types in python, and they all do different things:

1. Numeric Types

• int – Integer numbers (e.g., 5, 3, 100)
• float – Floating-point numbers (e.g., 3.14, 0.001)
• complex – Complex numbers (e.g., 2 + 3j)

2. Text Type

• str – String of characters (e.g., "Hello", 'Jake')
