UnicodeEncodeError: ‘ascii‘ codec can‘t encode characters in position ..

python遍历读取txt时，可能会遇到报错

UnicodeEncodeError: 'ascii' codec can't encode characters in position ..

原来的代码：

 testFile = '/Users/magicliu/work/1_self/xinyue-mall-fq/template/index/index.html'
 f3 = io.open(testFile, 'r', encoding='UTF-8')
 for s in f3.readlines():
     print(s) # 报错

解决方法

import sys
reload(sys)
sys.setdefaultencoding("utf-8")  # 设置环境为utf-8

 testFile = '/Users/magicliu/work/1_self/xinyue-mall-fq/template/index/index.html'
 f3 = io.open(testFile, 'r', encoding='UTF-8')
 for s in f3.readlines():
     print(s.encode('utf-8')) # 字符串转utf-8即可
