##### Series 转换 - [[Series.astype()]] 数据类型转换 ```python Series.convert_dtypes([infer_objects, ...]) # 自动转换最佳数据类型 Series.copy(deep=True) # 拷贝 Series.bool() # 转布尔类型 Series.to_numpy([dtype, copy, na_value]) # 转ndarray Series.to_list() # 转列表 Series.to_period([freq, copy]) # DatetimeIndex 转 PeriodIndex. Series.to_timestamp([freq, how, copy]) # PeriodIndex 转 DatetimeIndex ``` ##### DataFrame 转换 - [[DataFrame.astype()]] 类型转换
