我有一些我一直在处理的代码，它需要一个 csv 文件并将其转换为一个适当填充的 xls 文件。csv 文件是从客户网站发送给我的。我已经在他们的 8 个 csv 文件上对其进行了测试。前 7 个工作正常，我做了一些小调整以提高它的效率。这个最新的 csv 导致了一个错误。当我尝试前 7 个时，它们运行良好。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 中有 90 行。当我删除除 1 条记录之外的所有记录时，它起作用了。这让我相信有一些输入导致错误。为了解决这个问题，我在将数据从 csv 写入 xls 的每个实例周围添加了字符串标记。这次尝试失败了。当我查找其他答案时，他们通常处理 encode() 标签。我不直接使用其中的任何一个，尽管被调用的模块可能会使用它们。
有什么建议吗？谢谢你。
