Day 4 Homework – Loops in Python

This homework will help you practise for loop, while loop, range(), break and continue.

1. Print numbers from 1 to 10

Hint: Use for loop with range().

for i in range(1, 11):
    print(i)

2. Print even numbers from 1 to 20

Hint: Use step value in range().

for i in range(2, 21, 2):
    print(i)

3. Print "Hello" five times using while loop

Hint: Use a counter variable.

count = 1
while count <= 5:
    print("Hello")
    count += 1

4. Find the sum of numbers from 1 to 10

Hint: Start sum with 0 and add inside loop.

total = 0
for i in range(1, 11):
    total += i
print("Sum:", total)

5. Display multiplication table of a given number

Hint: Loop from 1 to 10.

n = int(input("Enter a number: "))
for i in range(1, 11):
    print(n, "x", i, "=", n * i)

6. Print numbers entered by user until user enters 0

Hint: Use condition based while loop.

n = int(input("Enter number: "))
while n != 0:
    print(n)
    n = int(input("Enter number: "))

7. Stop the loop when number is 5

Hint: Use break keyword.

for i in range(1, 10):
    if i == 5:
        break
    print(i)

8. Skip printing number 3

Hint: Use continue.

for i in range(1, 6):
    if i == 3:
        continue
    print(i)

9. Count number of digits in a number

Hint: Use while loop and // operator.

n = int(input("Enter number: "))
count = 0
while n > 0:
    count += 1
    n //= 10
print("Number of digits:", count)

10. Find factorial of a number

Hint: Multiply numbers from 1 to n.

n = int(input("Enter number: "))
fact = 1
for i in range(1, n + 1):
    fact *= i
print("Factorial:", fact)
