CSV模块返回第一列的BOM [英] csv module returning a BOM for first column

问题描述

我有一个csv文件，格式如下:

I have a csv file formatted like this:

type,type_mapping, style,style_mapping,Count
Residential,Residential,Antique,Antique,109
Antique,Residential,Antique,Antique,48
Apt/Garage,Commercial,Apt/Garage,Apartment,1

我正在使用Python(版本3)中的csv模块进行解析.这是我的代码:

I am parsing it using the csv module in Python (version 3). Here is my code:

import os
import csv

typeXref = dict()
with open('xref.csv') as csvData:
    csvRead = csv.reader(csvData)
    headers = next(csvRead)

    for index, row in enumerate(csvRead):
        typeXref[index] = {key: value for key, value in zip(headers, row)} 

print(typeXref)

由于某种原因，我的第一列连续返回标题中第一列的字节顺序标记 \ ufeff .

For some reason my first column continually returns the byte order mark \ufefffor the first column in the header.

408: {'\ufefftype': 'Residential', 'type_mapping': 'Residential', 
      ' style': 'Antique', 'style_mapping': 'Antique', 'Count': '109'}}

我认为这是由于我打开文件，使用 csv 模块读取内容或生成文件的方式引起的.

I assume this is due to the way I'm opening the file, reading the content with the csv module, or generating the file.

我可以弄清楚如何对该字段进行解码，但是可以确保我正确生成了文件，或者使用了 csv 模块属性.

I can figure out how to decode that one field, but would rather ensure I'm generating the file correctly, or using the csv module property.

推荐答案

您必须告诉您正在使用BOM读取utf-8文件:

You have to tell that you are reading an utf-8 file with BOM:

with open('xref.csv', encoding='utf-8-sig') as csvData:
    ....

然后将BOM剥离
