将多个CSV文件转换为UTF-8编码

Question

我需要将多个CSV文件（使用不同的编码）转换为UTF-8。

这是我的代码：

#find encoding and if not in UTF-8 convert it

import os
import sys
import glob
import chardet
import codecs

myFiles = glob.glob('/mypath/*.csv')

csv_encoding = []

for file in myFiles:
  with open(file, 'rb') as opened_file:
     bytes_file=opened_file.read()
     result=chardet.detect(bytes_file)
     my_encoding=result['encoding']
     csv_encoding.append(my_encoding)
        
print(csv_encoding)

for file in myFiles:
  if csv_encoding in ['utf-8', 'ascii']:
    print(file + ' in utf-8 encoding')
  else:
    with codecs.open(file, 'r') as file_for_conversion:
      read_file_for_conversion = file_for_conversion.read()
    with codecs.open(file, 'w', 'utf-8') as converted_file:
       converted_file.write(read_file_for_conversion)
    print(file +' converted to utf-8')

当我尝试运行此代码时，我得到以下错误： UnicodeDecodeError：'utf-8'编解码器无法解码位置5057的字节0xf3：无效的延续字节

有人能帮我吗？谢谢

您需要zip列表myFiles和csv\u encoding来对齐它们的值：

for file, encoding in zip(myFiles, csv_encoding):
    ...

您需要在调用中指定该值：

    ...
    with codecs.open(file, 'r', encoding=encoding) as file_for_conversion:

注意：在Python3中，不需要使用编解码器模块来打开文件。只需使用内置的open函数，并使用encoding参数指定编码。
