Function to find prime number
Did you know?
In number theory, a formula for primes is a formula generating the prime numbers, exactly and without exception. No such formula which is efficiently computable is known. A number of constraints are known, showing what such a "formula" can and cannot be. WebMar 27, 2024 · Given a number N, the task is to check if it is prime or not using Wilson Primality Test. Print ‘1’ if the number is prime, else print ‘0’. Wilson’s theorem states that a natural number p > 1 is a prime number if and only if (p - 1) ! ≡ -1 mod p OR (p - 1) ! ≡ (p-1) mod p Example :

It is also a good idea to turn it into a lambda function if you also want shorter code. factorial = lambda a:a and a*x (a-1)or 1 is_prime = lambda b:factorial (b-1)%b==b-1 You should then nest a while loop in a for loop to get the nth prime.
