写了一个读取log文件的Python脚本：
# -*- coding:utf-8 -*-
import os
import numpy as np
file = 'D:\pythonfile\test.log'
for line in open("test.log","r"):
print(line)但是在执行时报错：
执行代码报错：
Traceback (most recent call last):
File "D:/pythonfile/my-test225.py", line 8, in <module>
for line in open("test.log","r"):
UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 6946: illegal multibyte sequence
Process finished with exit code 1报错如图：
这是因为日志编码格式和读取日志的解码格式不一致导致的
方法一，读取文件指定“encoding='UTF-8'：
# -*- coding:utf-8 -*-
import os
import numpy as np
file = 'D:\pythonfile\test.log'
for line in open("test.log","r",encoding='UTF-8'):
print(line)方法二，读取文件指定rb（rb 以二进制读模式打开）：
# -*- coding:utf-8 -*-
import os
import numpy as np
file = 'D:\pythonfile\test.log'
# for line in open("test.log","rb"):
print(line)
