Python报UnicodeDecodeError: 'gbk' codec can't decode byte 0xad in position的解决办法

with open("input.txt") as f:
    for line in f:
        print(line)

按行读取文本文件时报错：UnicodeDecodeError: 'gbk' codec can't decode byte 0xad in position...

解决办法：

with open("input.txt",encoding='utf-8') as f:
    for line in f:
        print(line)
