获取DataFrame列名的一种方法是迭代DataFrame对象本身。DataFrame迭代器按定义顺序返回列名。 >>>forcolumnindata_frame:...print(column)...namepopulationstate 当需要将可迭代对象转换为列表时,可以在其上调用 Python 的内置list函数。 >>>list(data_frame)['name','population','state'] 但是,此方法的性能很慢。

To convert pandas dataframe column to list: Use pd.DataFrame() to read position_salaries as a pandas data frame. Use df["Position"] to get the column position from df Use position.values to get values of the position Use position_values.tolist() to get list of position_values as positio...
Convert Column to List from Pandas Dataframe df = pd.DataFrame({'A ':[1,3,5,7],'B ':[2,4,6,8]}) df["A"].tolist() df.A.values.tolist()
you have 5 options. You can convert a single row or column to list with thetolist()function, you can convert the entire DataFrame to a nested list, also with thetolist()function, and you can even convert the DataFrame into a list of tuples (to_records()function) or dictionaries (to...
现在我们使用reindex()函数对 python DataFrame 的列进行重新排序。你还可以使用列名列表并将该列表传递给reindex()方法,如下所示。 使用reindex()函数重新排序。reindex()方法将列作为列表接受。 带有列名的单个大括号用于按名称更改列顺序。 column_names=[0,2,3,1,4,"mean"]data=data.reindex(columns=column_na...
