原文:https://www . geesforgeks . org/python-sympy-composite pi-method/
借助 sympy.compositepi() 方法，我们可以求出小于或等于给定数目的合成数。
语法: compositepi(n)
参数: n–表示计算合成数的个数。
返回:返回小于或等于 n 的合成数。
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
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
