Python | sympy.primenu() method

Last Updated : 17 Sep, 2019

With the help of sympy.primenu() method, we can calculate the number of distinct prime factors for a given positive integer.

Syntax: primenu(n) Parameter: n - It denotes an integer. Returns: Returns the number of distinct prime factors for the given positive integer.

Example #1:

Python3

# import primenu() method from sympy
from sympy.ntheory.factor_ import primenu

n = 24

# Use primenu() method 
primenu_n = primenu(n) 
    
print("Number of distinct prime factors of {} = {} ".format(n, primenu_n)) # 2 and 3

Output:

Number of distinct prime factors of 24 = 2

Example #2:

Python3

# import primenu() method from sympy
from sympy.ntheory.factor_ import primenu

n = 2 * 3*7 * 11 * 13

# Use primenu() method 
primenu_n = primenu(n) 
    
print("Number of distinct prime factors of {} = {} ".format(n, primenu_n))

Output:

Number of distinct prime factors of 6006 = 5
