# Python Program to find all Prime Numbers in given Range

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 Truedef prime_numbers_in_range(start, end):
primes = []
for num in range(start, end + 1):
if is_prime(num):
primes.append(num)
return primesstart = 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

**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.**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.
