In the sympy module, we can get the next prime number for a given number n using sympy.nextprime() function. For n < 2^64 the answer is definitive; larger n values have a small probability of actually being pseudoprimes.
Syntax: sympy.nextprime() Parameter: n; number to be tested Return: next prime value
Code #1:
Python3
# Python program to get next prime number# using sympy.nextprime() method# importing sympy modulefrom sympy import *# calling nextprime function on different numbersprint(nextprime(7))print(nextprime(13))print(nextprime(2)) |
Output:
11 17 3
Code #2:
Python3
# Python program to check prime number# using sympy.isprime() method# importing sympy moduleimport sympy.ntheory as nt# calling isprime function on different numbersprint(nt.nextprime(30))print(nt.nextprime(13))print(nt.nextprime(2)) |
Output:
31 17 3
