如何将字典列表转换为元组列表？输入：

[{'x': 0.4711900100474648, 'y': 0.6294374442355883}, {'x': 0.4732473419066774, 'y': 0.629306809190704}, {'x': 0.47373722332499346, 'y': 0.6274779185623242}, {'x': 0.47363924704133026, 'y': 0.6273908285324014}, {'x': 0.4731493656230142, 'y': 0.6261715681134813}, {'x': 0.4722349203088243, 'y': 0.6252571227992915}, {'x': 0.47210428526394, 'y': 0.62521357778433}, {'x': 0.4709285698599815, 'y': 0.6253442128292143}, {'x': 0.47024273587433907, 'y': 0.62612802309852}, {'x': 0.4706019822477708, 'y': 0.6283052738465912}]

我要这个：

[(0,47..., 0.62...),(...,...)]

我尝试了这个：

tupleList = [tuple(val['x'], val['y']) for dic in listOfDict for key,val in dic.items()]

我收到错误TypeError：“ float”对象不可下标

或Y

list_of_points = [{'x': 0.4711900100474648, 'y': 0.6294374442355883}, {'x': 0.4732473419066774, 'y': 0.629306809190704}, {'x': 0.47373722332499346, 'y': 0.6274779185623242}, {'x': 0.47363924704133026, 'y': 0.6273908285324014}, {'x': 0.4731493656230142, 'y': 0.6261715681134813}, {'x': 0.4722349203088243, 'y': 0.6252571227992915}, {'x': 0.47210428526394, 'y': 0.62521357778433}, {'x': 0.4709285698599815, 'y': 0.6253442128292143}, {'x': 0.47024273587433907, 'y': 0.62612802309852}, {'x': 0.4706019822477708, 'y': 0.6283052738465912}]

points_tuples = [(p['x'], p['y']) for p in list_of_points]
