我有一些我一直在研究的代码，它采用csv文件并将其转换为适当填充的xls文件。 csv文件从客户端网站发送给我。我已经在8个csv文件上测试了它。前7个工作正常，我做了一些小调整，以提高效率。这个最新的csv导致了一个错误。当我尝试前7个时，他们工作正常。我得到的错误是：
Traceback (most recent call last):
File "/Users/USER/Documents/PYTHON/IFG User Update/code/ifg_user_update.py", line 232, in <module>
wb.save((os.path.expanduser("~/Downloads/Users_IFG_PTI")) + '.out.' + os.path.splitext((os.path.expanduser("~/Downloads/Users_IFG_PTI.xls")))[-1])

us = unicode(s, encoding)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 38: ordinal not in range(128)
第8个csv有90行。当我删除除1条记录以外的所有记录时这让我相信输入会导致错误。为了解释这一点，我在每个将数据从csv写入xls的实例中添加了字符串标记。这次尝试失败了。当我查找其他答案时，他们通常会处理encode（）标记。我不直接使用任何这些，尽管可能被调用的模块使用它们。
有什么建议吗？谢谢。

答案 0 :(得分：1)
问题是该输入文件中存在非标准的ascii字符，特别是具有十六进制值0xe2的字符。如果你有非标准的ascii，你需要删除有问题的字符或根据文件的真实编码对其进行解码（如utf-8或iso-8859-15等）。
例如
import codecs
filename = os.path.expanduser("~/Downloads/" + ifg_user_file)
data = [row for row in csv.reader(codecs.open(filename, 'U', encoding='utf-8'))]
