Python读取文件内容时报错：UnicodeDecodeError: 'gbk' codec can't decode byte...

Python代码如下：

#!/usr/bin/python3

print("读取的文件内容：")
with open("myfile.txt", mode='r') as f:
    for line in f:
        print(line, end="")

运行代码，异常信息如下：

Traceback (most recent call last):
  File "E:/git@github/python/python3/except/file.py", line 5, in <module>
    for line in f:
UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 28: illegal multibyte sequence

 

由于文件内容有中文，解决方法是在open方法指定参数encoding='UTF-8'：

#!/usr/bin/python3

print("读取的文件内容：")
with open("myfile.txt", mode='r', encoding='UTF-8') as f:
    for line in f:
        print(line, end="")
