python 2.7版本解决TypeError: 'encoding' is an invalid keyword argument for this function

data_file = open(“F:\MyPro\data.yaml”, “r”, encoding=’utf-8’)

运行的时候报错：TypeError: ‘encoding’ is an invalid keyword argument for this function

网上查找一番后，改成如下这样就可以搞定
import io

data_file = io.open(“F:\MyPro\data.yaml”, “r”, encoding=’utf-8’)
