In this tutorial, we will discuss how to find all prime numbers in a given range

Before going to the program first, let us understand what is Prime Numbers.

Prime Numbers:

• A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

Program code for Prime Numbers in a given Range in Python

# Prime Numbers in a Range in Python
def is_prime(num):
if num <= 1: return False for i in range(2, int(num ** 0.5) + 1): if num % i == 0: return False return True def prime_numbers_in_range(start, end): primes = [] for num in range(start, end + 1): if is_prime(num): primes.append(num) return primes start = int(input("Enter the start of the range: ")) end = int(input("Enter the end of the range: ")) primes = prime_numbers_in_range(start, end) print(f"Prime numbers between {start} and {end} are: {primes}") [/code]

Explanation

1. Function Definition: The is_prime function checks if a number is prime, and the prime_numbers_in_range function finds all prime numbers in a given range.
2. Main Program: The program prompts the user to enter the start and end of the range. It then finds all prime numbers in the range using the prime_numbers_in_range function and prints the result.

Output

• When you run the above program, it will prompt you to enter the start and end of the range.
• After entering the range, it will find all prime numbers in that range and print the result.

Conclusion

• In this tutorial, we learned how to find all prime numbers in a given range using a Python program.
• Understanding this concept is essential for solving various mathematical problems and enhancing your programming skills.
