Python | simpy.nextprime() method Last Updated : 09 Feb, 2023 Summarize Comments Improve Suggest changes Share Like Article Like Report 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 module from sympy import * # calling nextprime function on different numbers print(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 module import sympy.ntheory as nt # calling isprime function on different numbers print(nt.nextprime(30)) print(nt.nextprime(13)) print(nt.nextprime(2)) Output: 31 17 3 Comment More infoAdvertise with us Next Article Python | sympy.prime() method S Shivam_k Follow Improve Article Tags : Python SymPy Practice Tags : python Similar Reads Python | sympy.prime() method With the help of sympy.prime() method, we can find the nth prime, with the primes indexed as prime(1) = 2, prime(2) = 3, etc. Syntax: prime(n) Parameter: n - It denotes the nth prime number. Returns: Returns the nth prime number. Example #1: Python3 # import sympy from sympy import prime n = 5 # Use 1 min read Python | sympy.primepi() method With the help of sympy.primepi() method, we can find the number of prime numbers less than or equal to a given number. Syntax: primepi(n) Parameter: n - It denotes the number up to which the count of prime number is calculated. Returns: Returns the number of prime numbers less than or equal to n. Ex 1 min read Python | sympy.primeomega() method With the help of sympy.primeomega() method, we can calculate the number of prime factors counting multiplicities for a given positive integer. For example, primeomega(12) = 3, since 12 = 22 * 31. Therefore, number of prime factors = sum of multiplicities of prime factors, 2 + 1 = 3. Syntax: primeome 1 min read Python | sympy.primorial() method With the help of sympy.primorial() method, we can find the product of the first n primes (default) or the primes less than or equal to n (when nth=False), where n and nth are parameters to the method. Syntax: primorial(n, nth) Parameter: n - It denotes the number for which the product of first n pri 2 min read Python | sympy.primefactors() method With the help of sympy.primefactors() method, we can find the prime factors of a given number. Unlike factorint(), primefactors() does not return -1 or 0. Syntax: primefactors(n) Parameter: n - It denotes an integer. Returns: Returns a list of prime factors of the given integer. Example #1: Python3 1 min read Python next() method Python's next() function returns the next item of an iterator. Example Let us see a few examples to see how the next() method in Python works. Python3 l = [1, 2, 3] l_iter = iter(l) print(next(l_iter)) Output1 Note: The .next() method was a method for iterating over a sequence in Python 2.  It has 4 min read Like
