Question

python读取文件内容报错，应该是编码问题，求解答

#-*- coding:cp936 -*-
import os

def filters():
#获取当前路径
path = os.getcwd()
LogPath =path+"\Monkeylogcat.log"
LogLine = open(LogPath)
Results = {}
Keywords = "E/AndroidRuntime"
Mobo = "mobogenie"
for line in LogLine:
if (Keywords in line) and (Mobo in line):
Results[line] = 1
if line in Results.keys():
Results[line]+=1

LogLine.close()

Output = open('result.txt', 'w')
Output.write("Key\tnum\n")

keys = Results.keys()
for key in keys:
Output.write(key)
Output.write("\t")
Output.write(Results[key])
Output.write("\n")
Output.close()

if __name__ == "__main__":

filters()
报错：UnicodeDecodeError: 'gbk' codec can't decode bytes in position 7299-7300: illegal multibyte sequence

Answer 1

建议用codecs.open替代open; 若LogPath文件是以utf-8编码格式保存的:
LogLine = open(LogPath) ==> LogLine = codecs.open(LogPath, 'r', 'utf-8')

追问

LogLine = codecs.open(LogPath, 'r', 'utf-8')
NameError: global name 'codecs' is not defined
提示这个 错误
LogLine = open(LogPath, 'r', 'utf-8')
TypeError: an integer is required
咋回事截，以前读文本文件从来没有过这样的问题

追答

codecs是python的一个模块，你在使用前需要先import

#-*- coding:cp936 -*-    
import os
import codecs
..

Answer 2

类型不匹配
Output.write(Results[key])//这里Results[key]为int类型，加一个类型转换str(Results[key])

追问

恩恩，那块是有点问题，可是这个报错是读文件的时候出现的，不是写文件的时候出的

Answer 3

import os,sys
reload(sys)
sys.setdefaultencoding('utf-8')
在上面加上这几句吧
