UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb9 in position 16: invalid start byte

读取一个csv文件失败，提示：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb9 in position 16: invalid start byte

解决办法：使用Notepad++打开该csv文件，然后转为UTF-8编码

 import csv

 csv_reader=csv.reader(open('P020180206560372967623.csv',encoding='utf-8'))

 for row in csv_reader:

     print(row)
