列表索引必须是整数或切片，而不是元组：TypeError-Python

Question

我正在尝试调用一个用python编写的AWS lambda函数，它需要一个2D数组作为输入，但是在解析该数组时，python代码会引发以下错误  “列表索引必须是整数或切片，而不是元组：TypeError”

正在解析此列表的代码

# Input:
#    "utilityRates": [[0, 600, 0.2, 1, 366], [600, 900, 0.15, 1, 366], [900, 1440, 0.3, 1, 366]]

    TempElectricityRate = request["utilityRates"]
    print(TempElectricityRate)
    ElectricityRate = numpy.zeros((3,5))
    for x in range(0, 3):
        ElectricityRate[x,0] = TempElectricityRate[x,0]
        ElectricityRate[x,1] = TempElectricityRate[x,1]
        ElectricityRate[x,2] = TempElectricityRate[x,2]
        ElectricityRate[x,3] = TempElectricityRate[x,3]
        ElectricityRate[x,4] = TempElectricityRate[x,4]
