对于嵌套字典,我已尝试了所有可能的解决方案,但无法使任何东西正常工作,因为我的字典是列表和字典的组合:
我从Oandapyv20得到这个结果:

如何将其转换为熊猫数据帧?在
例如,这将给出一个错误:
^{pr2}$还有这个:
reform = {(level1_key, level2_key, level3_key): values
for level1_key, level2_dict in x.items()
for level2_key, level3_dict in level2_dict.items()
for level3_key, values in level3_dict.items()}
AttributeError: 'list' object has no attribute 'items'
是否可以将上述内容输入到数据帧中,而不必进行绝望的尝试,包括for循环和try&except?在
提前谢谢
你只需要申请
pd.Series
