Python | sympy.primeomega()方法
原文:https://www.geesforgeks.org/python-sympy-prime omega-method/
借助 sympy.primeomega() 方法，我们可以计算出给定正整数的计算重数的素因子个数。例如 primeomega(12) = 3 ，因为12 = 22 31T9】。因此，素因子数=素因子的倍数之和， 2 + 1 = 3。*
语法:素数(n)
参数: n–表示整数。
返回:返回给定正整数的重数素数。
示例#1:
# import primeomega() method from sympy
from sympy.ntheory.factor_ import primeomega
n = 24
# Use primeomega() method
primeomega_n = primeomega(n)
print(" Number of prime factors of {} = {} ".format(n, primeomega_n))
输出:
Number of prime factors of 24 = 4
例 2:
# import primeomega() method from sympy
from sympy.ntheory.factor_ import primeomega
n = 120
# Use primeomega() method
primeomega_n = primeomega(n)
print(" Number of prime factors of {} = {} ".format(n, primeomega_n))
输出:
Number of prime factors of 120 = 5
