In the world of mathematics, prime numbers have always fascinated researchers and mathematicians.

They are unique numbers that are only divisible by 1 and themselves. However, there is a special type of prime numbers called twin primes.

Twin primes are pairs of prime numbers that have a difference of 2 between them. For example, (3, 5), (11, 13), and (17, 19) are all twin prime pairs.

**What are Twin Prime Number?**

Twin prime numbers are pairs of prime numbers that differ by 2. These pairs of primes are closely adjacent to each other and share a unique relationship.

The discovery of twin primes dates back to ancient times, and they have intrigued mathematicians for centuries.

For example, (3, 5) is a twin prime pair since the difference between them is 2. Similarly, (11, 13) and (17, 19) are also twin prime pairs.

The twin prime conjecture, which proposes that there are infinitely many twin primes, remains an unsolved problem in number theory.

Python provides a straightforward and efficient way to implement algorithms, making it an excellent choice for this task.

**Step 1: Prime Number Check**

Before we can generate twin prime numbers, we need a mechanism to identify prime numbers.

Let’s start by creating a function to check if a given number is prime or not. We’ll call this function `is_prime()`

.

```
def is_prime(num):
if num < 2:
return False
for i in range(2, int(num ** 0.5) + 1):
if num % i == 0:
return False
return True
```

In the above code snippet, we begin by checking if the number is less than 2.

Since prime numbers are defined as numbers greater than 1, any number less than 2 cannot be prime. We return `False`

in such cases.

Next, we iterate from 2 to the square root of the given number plus 1. This optimization reduces the number of iterations required to check if a number is prime.

If the number is divisible by any of the integers in this range, it is not prime, and we return `False`

.

If the number passes the divisibility check for all integers in the range, it is prime, and we return `True`

.

**Step 2: Generating Twin Prime Numbers**

Now that we have a mechanism to check prime numbers, we can proceed to generate twin primes.

We’ll define a function named `generate_twin_primes()`

that takes a range of numbers and returns all the twin prime pairs within that range.

```
def generate_twin_primes(start, end):
twin_primes = []
for num in range(start, end + 1):
if is_prime(num) and is_prime(num + 2):
twin_primes.append((num, num + 2))
return twin_primes
```

In the code above, we initialize an empty list `twin_primes`

to store the twin prime pairs. Then, we iterate through the range of numbers from `start`

to `end`

.

For each number in the range, we use the `is_prime()`

function to check if both the number and its adjacent number (obtained by adding 2) are prime.

If both numbers are prime, we have found a twin prime pair, and we append it to the `twin_primes`

list.

Finally, we return the `twin_primes`

list containing all the twin prime pairs within the specified range.

**Step 3: Running the Twin Prime Program**

Now that we have implemented the necessary functions, let’s write the main code to execute the twin prime number program.

```
start_range = 1
end_range = 100
print("Twin Prime Number Program in Python")
print("-----------------------------------")
print(f"Generating twin prime numbers between {start_range} and {end_range}:")
print()
twin_primes = generate_twin_primes(start_range, end_range)
for prime_pair in twin_primes:
print(prime_pair)
```

In the code snippet above, we define the `start_range`

and `end_range`

variables to specify the range of numbers within which we want to generate twin primes.

We then print a header and a description of the program.

Next, we call the `generate_twin_primes()`

function with the specified range and store the result in the `twin_primes`

list.

Finally, we iterate over the `twin_primes`

list and print each twin prime pair.
