Python：将数组的元组转换为2d数组

Question

我有以下内容：

  CCM = ([
       [1.06301910149183, 0.00722151174898679, -0.0646501819773272], 
       [0.0343462908139148, 0.93978476472001, 0.016122360796017],
       [0.000718294712585651, 0.0672092385672176, 0.867165723476061]
    ],)

我希望将其转换为：

  CCM = [
        [1.06301910149183, 0.00722151174898679, -0.0646501819773272], 
        [0.0343462908139148, 0.93978476472001, 0.016122360796017], 
        [0.000718294712585651, 0.0672092385672176, 0.867165723476061]
    ]

我尝试了以下内容：

    ccm = list(CCM)
    CCM = [list(item) for item in ccm]

但我得到了：

CCM=[[
    [1.06301910149183, 0.00722151174898679, -0.0646501819773272], 
    [0.0343462908139148, 0.93978476472001, 0.016122360796017], 
    [0.000718294712585651, 0.0672092385672176, 0.867165723476061]
]]

这不是我想要的。

谢谢
