【问题描述】:
我正在从http://www.gapminder.org/data/ 导入 excel 表然后我想切换表的列和行。这就是我得到的错误: “UnicodeDecodeError:‘ascii’编解码器无法解码位置 23389 中的字节 0xc3:序数不在范围内 (128)”
我试图用 DataFrame.decode('utf-8') 但它说DataFrame没有这样的属性。
出现该错误是因为 transpose 无法将某些数据转换为 ascii。那正确吗?但是当我的表是纯数字时,为什么我们需要这样做呢?
非常感谢。
有更多关于错误的信息:

在我花了 40 分钟后,问题自行解决了,我不知道如何解决。我唯一做的就是添加了这段代码:
#encoding=utf8
import sys
reload(sys)
sys.setdefaultencoding('utf8')
但是当我删除这个和平时,它仍然有效。有人知道为什么吗?谢谢!!!!
