Module 2: Variables and Data Types

Activity 1: What are variables?

• Understanding what variables are and their importance in programming.
• Exploring the concept of variables as containers for storing and manipulating data.
• Learning about variable naming conventions and best practices.

Activity 2: Declaring and assigning variables

• Learning how to declare variables in Python.
• Understanding variable assignment and the use of the assignment operator =.
• Exploring different ways to assign values to variables, including literals and expressions.

Activity 3: Data types in Python

• Exploring the different data types available in Python, including:
  • Numeric types: Integers, floating-point numbers, and complex numbers.
  • Strings: Manipulating and concatenating strings.
  • Booleans: Working with True and False values.
  • None: Understanding the special None value.
  • Lists: Introduction to lists and their operations.
  • Dictionaries: Introduction to dictionaries and key-value pairs.
• Understanding type inference and explicit type declarations in Python.

Practice Exercises:

1. Calculate the area of a rectangle:

   • Declare two variables, width and height, and assign them appropriate values.
   • Calculate the area of the rectangle by multiplying width and height.
   • Store the result in a variable called area.
   • Finally, print the value of area.

2. Concatenate strings:

   • Declare two variables, first_name and last_name, and assign them your first and last name, respectively.
   • Create a new variable called full_name and concatenate first_name and last_name.
   • Finally, print the value of full_name.

3. Determine the data type:

   • Declare a variable called data and assign it a value of your choice.
   • Use the type() function to determine the data type of data.
   • Finally, print the result.

Estimated time to complete this module is approximately 4-6 hours.
