Python | sympy.is_prime() method

In the sympy module, we can test whether a given number n is prime or not using sympy.is_prime() function. For n < 2^64 the answer is definitive; larger n values have a small probability of actually being pseudoprimes. 

Note that Negative numbers (e.g. -13) are not considered prime numbers.

Syntax:  sympy.is_prime()
