Python | sympy.primenu()方法
原文:https://www.geeksforgeeks.org/python-sympy-primenu-method/
借助 sympy.primenu() 方法，我们可以计算给定正整数的不同素数因子的个数。
语法:素数(n)
参数: n–表示整数。
返回:返回给定正整数的不同质因数的个数。
示例#1:
# 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
输出:
Number of distinct prime factors of 24 = 2
例 2:
# 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))
输出:
Number of distinct prime factors of 6006 = 5
