python计算滑动平均的代码

以下是一个简单的 Python 代码，用于计算滑动平均：

def moving_average(data, window_size):
    # 确保窗口大小不超过数据长度
    window_size = min(window_size, len(data))
    # 初始化滑动平均值列表
    moving_averages = []
    # 遍历数据
    for i in range(len(data)):
        if i < window_size:
            # 如果数据不足以填满窗口，直接取平均值
            moving_averages.append(sum(data[:i+1]) / len(data[:i+1]))
        else:
            # 计算滑动平均值
            moving_averages.append(sum(data[i-window_size+1:i+1]) / window_size)
    return moving_averages

使用方法：

data = [1, 2, 3, 4, 5, 6, 7, 8, 9]
window_size = 3
moving_averages = moving_average(data, window_size)
print(moving_averages)

输出结果：

[1.0, 1.5, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0]
