Weights-Calc
一个简单易用的Python加权计算库,提供多种加权算法
安装
pip install weights
功能
- 加权计算: 基础的加权平均计算
- 加权随机: 根据权重进行随机选择
- 时间衰减加权: 基于时间的指数衰减加权
使用方法
导入
方法1
import importlib
Weights_Calc = importlib.import_module('Weights-Calc')
方法2
Weights_Calc = __import__('Weights-Calc')
加权计算
values = [10, 20, 30]
weights = [0.2, 0.3, 0.5]
result = Weights_Calc.weighted_calculate(values, weights)
print(result) # 输出: 23.0
加权随机
items = ['A', 'B', 'C']
weights = [1, 2, 3]
selected = Weights_Calc.weighted_random(items, weights)
print(selected) # 输出: ['B'] (概率更高)
时间衰减加权
values = [100, 200, 300]
dates = [1, 5, 10] # 时间点
half_life = 7 # 半衰期
result = Weights_Calc.time_decay_weighted(values, dates, half_life)
print(result)
API参考
