我从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)”
我试图使用编码/解码DataFrame DataFrame.decode('utf-8')但它表示DataFrame没有这样的属性。
发生错误是因为转置无法将某些数据转换为ascii。是对的吗?但是,当我的桌子是纯数字时,为什么我们需要这样做呢?
非常感谢你。
有关于错误的更多信息:

我花了40分钟后,问题解决了,我不知道如何。我唯一做的就是添加了这段代码:
#encoding=utf8
import sys
reload(sys)
sys.setdefaultencoding('utf8')
但是当我删除这种和平时,它仍然有效。有人知道为什么吗?谢谢!!!!
答案 0 :(得分:0)
如果没有更多关于你的ipython会话的具体知识,权威性地回答有点困难,但这里有一些有根据的猜测:
至于为什么你会得到那个错误,即使你的数据都是数字,也很可能来自一个索引标签(可能包含一些文本)。
至于为何在删除该代码时它仍然有效,如果您在iPython笔记本中工作,那么一旦您运行代码将默认编码设置为utf-8,该设置将保持有效,直到
