很多朋友在使用Python中pandas讀取csv文件時(shí)，出現(xiàn)編碼格式問題，接下來(lái)通過(guò)本文給大家分享解決Python中pandas讀取*.csv文件出現(xiàn)編碼問題,需要的朋友可以參考下

1、問題

在使用Python中pandas讀取csv文件時(shí)，由于文件編碼格式出現(xiàn)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

During handling of the above exception, another exception occurred:

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

我認(rèn)為該問題是由于文件編碼格式不是'utf-8'所導(dǎo)致的，因此，嘗試將文件格式進(jìn)行轉(zhuǎn)換，轉(zhuǎn)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(diǎn)擊保存即可

總結(jié)
