PrimePy

1.3 · abandoned · verified Fri Apr 10

PrimePy is a Python library designed to simplify operations related to prime numbers, offering functions for checking primality, generating primes within a range, and finding prime factors. The library's last update was in May 2018, and it is currently unmaintained, making it potentially unsuitable for new projects or critical applications.

Warnings

breaking The library is unmaintained since its last release in May 2018. This means there are no ongoing bug fixes, security updates, or compatibility assurances with newer Python versions or dependencies.
Fix: Consider using actively maintained alternatives like `sympy`, `primefac`, or implementing prime number logic manually for critical applications. Evaluate thoroughly before using in production environments.
gotcha The `primes.check(1)` function incorrectly returns `True`, despite 1 not being considered a prime number by mathematical definition.
Fix: Always add an explicit check for `n > 1` when using `primes.check(n)` if adherence to the strict definition of prime numbers (greater than 1) is required.

Install

pip install primePy Install with pip

Imports

primes
```
from primePy import primes
```

Quickstart

Demonstrates basic usage of `primePy` to check if a number is prime, find its prime factors, and get a list of the first 'n' prime numbers.

from primePy import primes

# Check if a number is prime
print(f"Is 17 prime? {primes.check(17)}")
print(f"Is 10 prime? {primes.check(10)}")

# Get prime factors of a number
print(f"Prime factors of 252: {primes.factors(252)}")

# Get the first 'n' prime numbers
print(f"First 5 primes: {primes.first(5)}")
