Python 将字典列表转换为numpy数组

我有一个字典列表如下：

{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}

我正在尝试将其转换为一个numpy数组，其中两列仅用于“x”和“z”值

有没有一个简单的方法可以做到这一点

像这样：

data = [{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044},
{'x': -0.002222188049927354, 'y': 0.014999999664723873, 'z': -0.45333319902420044}]

pd.DataFrame(data)[['x', 'z']].values

array([[-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ],
       [-0.00222219, -0.4533332 ]])

thearray = pd.DataFrame(dictlist)[['x', 'z']].values

像这样：

thearray = pd.DataFrame(dictlist)[['x', 'z']].values
