Introduction to Python (copy)
Recap
Congratulations on completing the first section of our Python course!
Let's take a moment to review the key concepts and skills you've mastered:
Print Statements
You've learned how to use print() to display text and numbers on the screen. This is fundamental for any Python program as it allows you to output results and messages, making your code interactive.
Recall the example from before:
print("Hello World!")
Comments
You've practiced using comments in your code, which are lines that Python ignores.
Comments are written with a # at the beginning of the line and are crucial for documenting what your code is doing. This makes your code easier to understand and maintain for you and others who might read your code later.
Here is a quick reminder example:
print("Welcome to Aisle 3: Snacks, Chips, and Sodas") print("Potato Chips") #print("Milk")
Simple Math Operations
You've applied basic arithmetic operations — addition (+), subtraction (-), multiplication (*), and division (/).
These operations are essential for performing calculations, which you practiced in the context of managing inventory and prices in a grocery store.
Run the following multiplication example:
# Multiplication: # Calculating the cost of a 3.5-pound bundle of bananas when bananas cost $1.20 per pound. print(3.5 * 1.20)
1. What is the purpose of the print() function in Python?
2. In Python, how do you write a comment that the interpreter will ignore?
3. What is the correct operator to use for division in Python?
