Python Loop Challenges Explained

1. The Countdown

Write a loop that counts down from 10 to 1, then prints "Happy New Year!".

for i in range(10, 0, -1):
    print(i)  # Indented: Inside the loop
print("Happy New Year!") # Not Indented: After loop
            

Start

Waiting...

Calculate the sum of all numbers from 1 to 100 and print the final result.

total = 0
for i in range(1, 101):
    total = total + i  # Indented: Adds every time
print(total) # Not Indented: Prints once at end
            

(Visualizer simplified to range 1-5)

Current i

total 0

total = 0 + 1
