Python Pandas read_csv保持列顺序 [英] Python Pandas read_csv Keep Column Order

问题描述

我正在将CSV文件读入熊猫:

I am reading a CSV file into pandas:

df = pd.read_csv('file.csv')

但是，我注意到没有保留列顺序.我在文档中找不到任何说明来解释在读取CSV文件时如何保持列顺序的东西.

However, I notice that column order is not preserved. I can't find anything in the docs that explain how to keep the column order when reading in the CSV file.

推荐答案

read.csv将表格数据转换为DataFrame对象.由于DataFrame是kwargs词典，因此不能坚持使用顺序.

read.csv convert tabular data into DataFrame object. Since DataFrame are kwargs dictionary, order is not persevered.

来自 DataFrame 和 read.csv
