A fun beginner programming course for young programmers

Let's teach Python how to add two numbers!
# Example 1: Addition of Two Variables
# Give numbers to Python
a = 10
b = 20
# Ask Python to add them
total = a + b
# Show the answer
print("First Number =", a)
print("Second Number =", b)
print("Sum =", total)
First Number = 10
Second Number = 20
🎉 Sum = 30
Python helps students calculate total marks and average.
# Example 2: Three Subjects
math = 85
english = 90
science = 80
total = math + english + science
average = total / 3
print("Math =", math)
print("English =", english)
print("Science =", science)
print("Total =", total)
print("Average =", average)
Math = 85
English = 90
Science = 80
Total = 255
⭐ Average = 85
Python can help shop owners calculate payments.
# Example 3: Supermarket Bill
apple = 50
banana = 30
orange = 40
total = apple + banana + orange
tax = total * 0.15
net = total + tax
print("Apple =", apple,"Birr")
print("Banana =", banana,"Birr")
print("Orange =", orange,"Birr")
print("Total =", total,"Birr")
print("Tax =", tax,"Birr")
print("Net =", net,"Birr")
Apple = 50 Birr
Banana = 30 Birr
Orange = 40 Birr
Total = 120 Birr
Tax = 18 Birr
🎉 Net Amount = 138 Birr
Now Python asks the user to enter numbers!
# EXAMPLE 4: ADDITION OF TWO VARIABLES
# Using User Input
# Step 1: Get values from user
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))
# Step 2: Process (Addition)
total = a + b
# Step 3: Display result
print("First Number =", a)
print("Second Number =", b)
print("Sum =", total)
Enter first number: 8
Enter second number: 9
First Number = 8
Second Number = 9
🎉 Sum = 17
Python can calculate student results automatically.
# EXAMPLE 5:
# TOTAL AND AVERAGE OF THREE SUBJECTS
# Step 1: Input marks
math = float(input("Enter Math Marks: "))
english = float(input("Enter English Marks: "))
science = float(input("Enter Science Marks: "))
# Step 2: Process
total = math + english + science
average = total / 3
# Step 3: Display result
print("\n===== RESULT =====")
print("Math Marks =", math)
print("English Marks =", english)
print("Science Marks =", science)
print("------------------")
print("Total Marks =", total)
print("Average Marks =", average)
Enter Math Marks: 80
Enter English Marks: 75
Enter Science Marks: 90
Total Marks = 245
⭐ Average Marks = 81.67
Python helps shopkeepers calculate customer payments.
# EXAMPLE 6:
# SUPERMARKET BILL USING USER INPUT
# Step 1: Input fruit prices
apple = float(input("Enter Apple Price: "))
banana = float(input("Enter Banana Price: "))
orange = float(input("Enter Orange Price: "))
# Step 2: Process
total = apple + banana + orange
tax = total * 0.15
net = total + tax
# Step 3: Display result
print("\n===== SUPERMARKET RECEIPT =====")
print("Apple Price =", apple, "Birr")
print("Banana Price =", banana, "Birr")
print("Orange Price =", orange, "Birr")
print("------------------------------")
print("Total Cost =", total, "Birr")
print("Tax (15%) =", tax, "Birr")
print("Net Amount =", net, "Birr")
Enter Apple Price: 120
Enter Banana Price: 140
Enter Orange Price: 100
Total Cost = 360 Birr
Tax (15%) = 54 Birr
🎉 Net Amount = 414 Birr
Create a real shopping program that calculates the cost of three different fruits.
# EXAMPLE 7:
# SUPERMARKET FRUIT BILL
# Step 1: First fruit information
fruit1 = input("Enter first fruit name: ")
price1 = float(input("Enter price per kg: "))
kg1 = float(input("Enter kilogram: "))
# Calculate first fruit cost
cost1 = price1 * kg1
# Step 2: Second fruit information
fruit2 = input("Enter second fruit name: ")
price2 = float(input("Enter price per kg: "))
kg2 = float(input("Enter kilogram: "))
# Calculate second fruit cost
cost2 = price2 * kg2
# Step 3: Third fruit information
fruit3 = input("Enter third fruit name: ")
price3 = float(input("Enter price per kg: "))
kg3 = float(input("Enter kilogram: "))
# Calculate third fruit cost
cost3 = price3 * kg3
# Step 4: Calculate total cost
total_cost = cost1 + cost2 + cost3
tax = total_cost * 0.15
net_amount = total_cost + tax
# Step 5: Display receipt
print("\n======== FRUIT RECEIPT ========")
print(fruit1, "=", cost1, "Birr")
print(fruit2, "=", cost2, "Birr")
print(fruit3, "=", cost3, "Birr")
print("------------------------------")
print("Total Fruit Cost =", total_cost, "Birr")
print("Tax (15%) =", tax, "Birr")
print("Net Amount =", net_amount, "Birr")
Enter first fruit name: Banana
Enter price per kg: 100
Enter kilogram: 2
Enter second fruit name: Orange
Enter price per kg: 50
Enter kilogram: 3
Enter third fruit name: Apple
Enter price per kg: 90
Enter kilogram: 2
Banana = 200 Birr
Orange = 150 Birr
Apple = 180 Birr
Total Fruit Cost = 530 Birr
Tax (15%) = 79.5 Birr
🎉 Net Amount = 609.5 Birr
Python can communicate with users by taking text information.
# Simple Conversation Using String Input
name = input("🤖 Hello! What is your name? ")
age = input("🤖 How old are you? ")
city = input("🤖 Where do you live? ")
print("\n====================")
print("🐍 Python Conversation")
print("====================")
print("Hello", name, "😊")
print("You are", age, "years old.")
print("You live in", city, ".")
print("Nice to meet you! Keep learning Python 🚀")
🤖 Hello! What is your name? Geta
🤖 How old are you? 25
🤖 Where do you live? Addis Ababa
