处理中文语料 codec can‘t decode byte 0xaa in position 134: illegal multibyte sequence问题

import os
import jieba
import chardet
path = "D:/python/复旦中文文本训练集/train/"
path1 = "D:/python/复旦中文文本训练集/"

def check(path: str):
    with open(path, 'rb') as f:
      print(chardet.detect(f.read())['encoding'], ': ', i)

发现都是GB2312编码

 但是open起来就有问题了

# 获取语料库文件夹下所有文件名
filelist = []
for i in os.listdir(path):
    for j in os.listdir(path+i):
        filelist.append(path+i+"/"+j)

# 语料拼接起来放一起
str = ""        
for file in filelist:
    with open(file, encoding='GB2312') as f:        
        article = f.read()
        str += article

报错：'gb2312' codec can't decode byte 0xaa in position 134: illegal multibyte sequence

网上一搜，说GB2312对于繁体字会报错，于是改成更广范围的编码格式gb18030。大部分的文件都好了，还是有些报错的，不过很少了

祭出绝招errors = 'ignore'，搞定。

str = ""        
for file in filelist:
    with open(file, encoding='gb18030',errors = 'ignore') as f:        
        article = f.read()
        str += article

fo = open(path1+"train.txt", 'w', encoding='utf-8')
fo.write(str)
fo.close()
