Prime Number Program in Python

Numbers have always fascinated humanity, and among them, prime numbers stand out as captivating mathematical entities.&nbsp;
Prime numbers are integers greater than 1 that possess a unique quality &ndash; they can only be divided evenly by 1 and themselves, with no other factors in between.&nbsp;
The ways to identify prime numbers has been interesting for mathematicians and programmers alike, leading to the development of efficient algorithms to tackle this timeless challenge.
Here, we will explore the different approaches on how to find prime numbers in Python. We will showcase a variety of programs, providing clear examples, output, and detailed code explanations to simplify the process.
By going through these Python program examples, you will gain a deeper understanding of number divisibility, loops, conditionals, and other fundamental programming concepts in Python. Moreover, you will explore the strengths and weaknesses of different prime checking algorithms, enabling you to make informed decisions when selecting the most suitable approach for your specific requirements.
<h2 dir="ltr">Prime Number Logic in Python</h2>
The logic to check if a number is prime in Python generally involves iterating from 2 to the square root of the number (inclusive) and checking if the number is divisible by any of those values. If it is divisible by any value, then it is not a prime number. Otherwise, it is a prime number.
Here's a step-by-step explanation of the prime number logic in Python:
<ul>
<li dir="ltr" aria-level="1">
Start with a number. Let's call it num.
</li>
<li dir="ltr" aria-level="1">
Check if num is less than or equal to 1. If so, it is not a prime number. Return False.
</li>
<li dir="ltr" aria-level="1">
Iterate through numbers from 2 to the square root of num (inclusive). You can use the range function with the appropriate arguments.
</li>
<li dir="ltr" aria-level="1">
For each number i in the range, check if num is divisible by i. If num is divisible by i without a remainder, it means num is not a prime number. Return False.
</li>
<li dir="ltr" aria-level="1">
If the loop completes without finding any factors, it means num is a prime number. Return True.
</li>
</ul>
