Python sympy.compositepi()方法

在sympy.compositepi()方法的帮助下，我们可以找到小于或等于一个给定数的复合数。

语法: compositepi(n)

参数 :
n –它表示计算复合数的数量，直至该数。

返回：返回小于或等于**n*的复合数的数量。

示例 #1:

# import compositepi() method from sympy
from sympy import compositepi
  
n = 10
  
# Use compositepi() method 
count_composites = compositepi(n) 
      
print("The number of composites numbers less than or equal to {} is {}".format(n, count_composites))

输出:

The number of composites numbers less than or equal to 10 is 5

示例 #2:

# import compositepi() method from sympy
from sympy import compositepi
  
n = 100
  
# Use compositepi() method 
count_composites = compositepi(n) 
      
print("The number of composites numbers less than or equal to {} is {}".format(n, count_composites))          

输出:

The number of composites numbers less than or equal to 100 is 74
