Python| sympy.primeomega() 方法

在sympy.primeomega()方法的帮助下，我们可以计算给定正整数的素数计数重数。例如， primeomega(12) = 3 ，因为12 = 2 ² * 3 ¹ 。因此，质因数的个数 = 质因数的重数之和， 2 + 1 = 3。

Syntax: primeomega(n)

Parameter:
n – It denotes an integer.

Returns: Returns the number of prime factors counting multiplicities for a given positive integer.

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 

示例 #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
