使用map将pandas dataframe转换为列表 我正在使用map将dataframe中的某些列转换为dicts的list。这是一个MWE,说明了我的问题。 import pandas as pd df = pd.DataFrame() df['Col1'] = [197, 1600, 1200] df['Col2'] = [297, 2600, 2200] df['Col1_a'] = [198, 1599, 1199]...
1.DataFrame DataFrame是一个二维的标签数据结构,其列的类型可能不同。你可以把它想象成一个电子表格或SQL表,或者Series对象的dict。它通常是最常用的pandas对象。和Series一样,DataFrame也接受许多不同类型的输入: Dict of 1Dndarrays, lists, dicts, or Series ...

DataFrame.from_dict() takes a dict of dicts or a dict of array-like sequences and returns a DataFrame.It operates like the DataFrame constructor except for the orient parameterwhich is 'columns' by default,but which can be set to 'index' in order to use the dict keys as row labels."...
