解决Python中pandas读取*.csv文件出现编码问题


						1、问题

在使用Python中pandas读取csv文件时，由于文件编码格式出现以下问题：





Traceback (most recent call last):

 File "pandas\_libs\parsers.pyx", line 1134, in pandas._libs.parsers.TextReader._convert_tokens

 File "pandas\_libs\parsers.pyx", line 1240, in pandas._libs.parsers.TextReader._convert_with_dtype

 File "pandas\_libs\parsers.pyx", line 1494, in pandas._libs.parsers._string_box_utf8

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 19: invalid start byte

During handling of the above exception, another exception occurred:

我认为该问题是由于文件编码格式不是'utf-8'所导致的，因此，尝试将文件格式进行转换，转换方式如下：

首先使用txt文本打开文件，然后另存为，在右下角将编码改为‘UTF-8'，点击保存即可
