The logic for identifying a prime number in Python involves checking if a number is divisible only by 1 and itself. Use a loop to test divisibility from 2 up to the square root of the number. If no divisors are found, it's prime.
FAQs & Answers
- What is a prime number? A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.
- How do you check if a number is prime in Python? You can check if a number is prime in Python by testing divisibility from 2 up to the square root of the number.
- What is the time complexity for checking prime numbers? The time complexity for checking if a number is prime using trial division is O(√n), where n is the number being checked.
- Are there built-in functions in Python for prime checking? Python does not have a built-in function specifically for prime checking, but you can implement this logic using loops or libraries.
