python 文件里面的编码问题

py36
with as 打开的
()里面可以直接加上第三个参数，encoding=‘utf-8’

py27
在f.write里面的东西后面使用.encode(‘utf-8’)

 with open(os.path.join(paths,'r2', 
            os.path.splitext(os.path.basename(ima))[0])+ ".txt", "w", encoding='utf-8') as f:
            f.write("The time is:{}s".format(time.time() - t)+"\n")
            for key in result:
#                f.write(result[key][1].encode("utf-8")) ##py27
                f.write(result[key][1])
                f.write("\n")
