编码问题：UnicodeDecodeError: ‘utf-8‘ codec can‘t decode byte 0xb3 in position

有一次报错如下：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb3 in position 0: invalid start byte

编码问题：f = open(txtPath,'r',encoding='utf-8')
 
改为：f = open(txtPath,'r',encoding='gbk')即可
print(f.read())

 

又有一次读取CSV文件时报错： 

import pandas as pd
content = pd.read_csv('news.csv',encoding='utf-8')
print(content.head())

报错如下：UnicodeDecodeError: 'utf-8' codec can't decode byte 0xba in position 0: invalid start byte

这里我将编码问题 utf-8 改为 gbk，还是报错。。。。报错如下：

UnicodeDecodeError: 'gbk' codec can't decode byte 0xa2 in position 93: illegal multibyte sequence

最后当我把程序改为：

import pandas as pd
content = pd.read_csv('news.csv',encoding='gb18030')
print(content.head())

最终成功

在出现编码问题的时候，从编码类型角度入手，往往能够解决问题

with open('film_info.csv','r') as f:
    df_fs = pd.read_csv('film_info.csv', sep=',', header=0, delimiter=None, names=None, skiprows=None, nrows=None,encoding='gbk', index_col=None, usecols=None)

想上图，我将utf-8编码改为gbk编码方式之后，就不再报错了
