問題描述：使用Python代碼將txt城市列表文件轉換為xls文件，源碼如下，

#!/usr/bin/env Python
# coding=utf-8
import os
import json
import xlwt
 
# 存放文件的目錄
filepath = ‘/home/tarena/python/20180312‘
 
 
def run():
    os.chdir(filepath)
    # 讀取文件內容
    with open(‘city.txt‘) as f:
        content = f.read()
    # 轉為json
    d = json.loads(content)
    file 
 
= xlwt.Workbook()
    # 添加sheet
    table = file.add_sheet(‘test‘)
    for row, i in enumerate(list(d)):
        table.write(row, 0, i)
        table.write(row, 1, d[i])
    file.save(‘city.xls‘)
 
if __name__ == "__main__":
    run()

報錯誤：json.decoder.JSONDecodeError: Unexpected UTF-8 BOM (decode using utf-8-sig): line 1 column 1 (char 0)錯誤，

分析原因是因為txt文件包含BOM字符，去掉BOM字符，在content = f.read()代碼下加上：

if content.startswith(u‘\ufeff‘):
      content = content.encode(‘utf8‘)[3:].decode(‘utf8‘)
