寫了一個讀取log文件的Python腳本：
# -*- coding:utf-8 -*-
import os
import numpy as np
file = 'D:\pythonfile\test.log'
for line in open("test.log","r"):
print(line)但是在執行時報錯：
執行代碼報錯：
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報錯如圖：
這是因為日志編碼格式和讀取日志的解碼格式不一致導致的
方法一，讀取文件指定“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，讀取文件指定rb（rb 以二進制讀模式打開）：
# -*- coding:utf-8 -*-
import os
import numpy as np
file = 'D:\pythonfile\test.log'
# for line in open("test.log","rb"):
print(line)
