6
7
8
9
10

Python Solution

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

Explanation

The range(1, 11) function generates numbers from 1 to 10.

Concepts Covered

  • for loop
  • range()

2. Python Program to Print Even Numbers from 1 to 20

Difficulty: Foundation

Problem Statement

Write a Python program to print all even numbers from 1 to 20.

Expected Output

2
4
6
8
10
12
14
16
18
20

Python Solution

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

Explanation

The third argument of range() specifies the step value.

Concepts Covered

  • for loop
  • range(start, stop, step)

3. Python Program to Calculate the Sum of First 10 Natural Numbers

Difficulty: Foundation

Problem Statement

Write a Python program to calculate the sum of numbers from 1 to 10.

Expected Output

Sum: 55

Python Solution

total = 0

for number in range(1, 11):
    total += number

print("Sum:", total)

Explanation

The variable total stores the running sum of all numbers.

Concepts Covered

  • for loop
  • Accumulator pattern

4. Python Program to Print the Multiplication Table of a Number

Difficulty: Foundation

Problem Statement

Write a Python program to print the multiplication table of a given number.

Python Solution

number = int(input("Enter a number: "))

for i in range(1, 11):
    print(f"{number} x {i} = {number * i}")

Sample Output

Enter a number: 5
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
...
5 x 10 = 50

Explanation

The loop repeats 10 times to generate the multiplication table.

Concepts Covered

  • for loop
  • range()
  • Formatted output

5. Python Program to Count the Digits in a Number

Difficulty: Practice

Problem Statement

Write a Python program to count the total number of digits in a given number.

Python Solution

number = int(input("Enter a number: "))
count = 0

while number != 0:
    number //= 10
    count += 1

print("Total Digits:", count)

Sample Output

Enter a number: 54892
Total Digits: 5

Explanation

Each iteration removes the last digit until the number becomes zero.

Concepts Covered

  • while loop
  • Integer division

6. Python Program to Reverse a Number

Difficulty: Practice

Problem Statement

Write a Python program to reverse a given number.

Python Solution

number = int(input("Enter a number: "))
reverse = 0

while number > 0:
    digit = number % 10
    reverse = reverse * 10 + digit
    number //= 10

print("Reversed Number:", reverse)

Sample Output

Enter a number: 12345
Reversed Number: 54321

Explanation

The last digit is extracted and added to the reversed number in each iteration.

Concepts Covered

  • while loop
  • Modulus operator

7. Python Program to Check Whether a Number is Prime

Difficulty: Practice

Problem Statement

Write a Python program to check whether a given number is prime.

Python Solution

number = int(input("Enter a number: "))

if number <= 1:
    print("Not a Prime Number")
else:
    is_prime = True

    for i in range(2, number):
        if number % i == 0:
            is_prime = False
            break

    if is_prime:
        print("Prime Number")
    else:
        print("Not a Prime Number")

Sample Output

Enter a number: 13
Prime Number

Explanation

A prime number has exactly two factors: 1 and itself.

Concepts Covered

  • for loop
  • break
  • Prime number logic

8. Python Program to Print a Right Triangle Star Pattern

Difficulty: Challenge

Problem Statement

Write a Python program to print the following star pattern.

Expected Output

*
**
***
****
*****

Python Solution

for row in range(1, 6):
    print("*" * row)

Explanation

The number of stars increases by one in each row.

Concepts Covered

  • Nested logic
  • Pattern printing

9. Python Program to Demonstrate break Statement

Difficulty: Challenge

Problem Statement

Write a Python program that prints numbers from 1 to 10 but stops when it reaches 6.

Python Solution

for number in range(1, 11):
    if number == 6:
        break

    print(number)

Expected Output

1
2
3
4
5

Explanation

The break statement immediately terminates the loop.

Concepts Covered

  • break
  • Loop control statements

10. Python Program to Demonstrate continue Statement

Difficulty: Challenge

Problem Statement

Write a Python program to print numbers from 1 to 10, but skip the number 5.

Python Solution

for number in range(1, 11):
    if number == 5:
        continue

    print(number)

Expected Output

1
2
3
4
6
7
8
9
10

Explanation

The continue statement skips the current iteration and moves to the next one.

Concepts Covered

  • continue
  • Loop control statements
