如何将上式用python表示出来，式子中的v(t)为一组数据

Answer 1

代码如下：

def v(vt):
    l = []
    for i in vt:
        if i <= 3.6 :
            l.append(0)
        elif i <= 7.2:
            l.append(5.2*(7.2-i))
        else:
            l.append(i)
    return l
            
print(v([1,3.6,4,7.2,8]))

结果：[0, 0, 16.64, 0.0, 8]
