1、問題
在使用Python中pandas讀取csv文件時，由于文件編碼格式出現以下問題：
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

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 19: invalid start byte
During handling of the above exception, another exception occurred:

我認為該問題是由于文件編碼格式不是'utf-8'所導致的，因此，嘗試將文件格式進行轉換，轉換方式如下：
首先使用txt文本打開文件，然后另存為，在右下角將編碼改為‘UTF-8'，點擊保存即可
