Unlocking the Secrets of Prime Numbers

Prime numbers have fascinated mathematicians for centuries. These unique integers, greater than 1, possess only two factors: 1 and themselves. Examples of prime numbers include 2, 3, 5, and 7, which cannot be divided evenly by any other number except 1 and themselves. On the other hand, 6 is not prime, as it can be expressed as 2 x 3 = 6.

The Power of Python

To explore prime numbers further, we’ll utilize Python’s capabilities. If you’re familiar with Python’s if…else statement, for loop, and break and continue statements, you’re ready to dive in.

A Pythonic Approach

We’ll create a program to identify prime numbers within a specified range. Our code will use the range() function to define the interval, storing the lower and upper bounds as lower and upper, respectively. Then, we’ll print the prime numbers within this range.

Code Breakdown

“`

Store the interval as lower and upper using Python range()

for num in range(lower, upper + 1):
# Check if the number is prime
if num > 1:
for i in range(2, num):
if (num % i) == 0:
break
else:
print(num)
“`

Unraveling the Logic

Our code iterates through the specified range, checking each number to see if it’s prime. If a number is greater than 1, we iterate from 2 to the number itself, checking for divisibility. If the number is divisible, we break the loop. Otherwise, we print the prime number.
