Dynamic typing in Python - Mini Project: Build & Apply

Dynamic typing in Python

📖 Scenario: Imagine you are creating a simple program that stores information about a product. The product's details can change, and you want to see how Python allows you to change the type of a variable easily.

🎯 Goal: You will create a variable to hold a product's price, then change its type from a number to a string, and finally to a boolean. This will show how Python's dynamic typing works.

📋 What You'll Learn

Create a variable called price and set it to the number 100

Create a variable called price and change its value to the string "One hundred"

Create a variable called price and change its value to the boolean True

Print the value and type of price after each change

💡 Why This Matters

🌍 Real World

Dynamic typing lets programmers write flexible code that can handle different kinds of data without strict type rules.

💼 Career

Understanding dynamic typing is important for Python developers to write clean and adaptable code in many real-world applications.

1

Create a variable with a number

Create a variable called price and set it to the number 100.

Python

# Create a variable called price and set it to 100
# Your code here

Need a hint?

Use the equals sign = to assign the number 100 to the variable price.

2

Change the variable to a string

Change the variable price to the string "One hundred".

Python

price = 100
# Change price to the string "One hundred"
# Your code here

Need a hint?

Assign the string "One hundred" to the variable price using =.

3

Change the variable to a boolean

Change the variable price to the boolean value True.

Python

price = 100
price = "One hundred"
# Change price to the boolean True
# Your code here

Need a hint?

Assign the boolean value True to the variable price.

4

Print the value and type after each change

Print the value and type of price after each change using print(price, type(price)). You need to print three times: after setting it to 100, after changing to "One hundred", and after changing to True.

Python

price = 100
print(price, type(price))
price = "One hundred"
print(price, type(price))
price = True
print(price, type(price))
# Your code here

Need a hint?

Use print(price, type(price)) after each assignment to show the value and its type.
