Python Pandas to_clipboard() UnicodeEncodeError: 'ascii' codec can't encoding character

Question

我想将数据框数据传递到剪贴板，以便粘贴到 Excel 中。问题是，字符 '\xe9' 导致了编码问题，如下所示：

>>> df.to_clipboard()
Traceback (most recent call last):
  File "C:\Python34\lib\site-packages\pandas\util\clipboard.py", line 65, in winSetClipboard
    hCd = ctypes.windll.kernel32.GlobalAlloc(GMEM_DDESHARE, len(bytes(text))+1)
TypeError: string argument without an encoding

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<pyshell#51>", line 1, in <module>
    df.to_clipboard()
  File "C:\Python34\lib\site-packages\pandas\core\generic.py", line 1028, in to_clipboard
    clipboard.to_clipboard(self, excel=excel, sep=sep, **kwargs)
  File "C:\Python34\lib\site-packages\pandas\io\clipboard.py", line 98, in to_clipboard
    clipboard_set(objstr)
  File "C:\Python34\lib\site-packages\pandas\util\clipboard.py", line 68, in winSetClipboard
    hCd = ctypes.windll.kernel32.GlobalAlloc(GMEM_DDESHARE, len(bytes(text, 'ascii'))+1)
UnicodeEncodeError: 'ascii' codec can't encode character '\xe9' in position 543793: ordinal not in range(128)

我解码了这个字符，它是一个重音é

>>> '\xe9'.encode().decode()
'é'

阅读to_clipboard() 的文档后，我注意到它说： 其他关键字传递给to_csv。好的，所以“其他关键字”是指来自to_csv() 的关键字参数——特别是我想使用encoding='cp1252'。

当我尝试这个时，to_clipboard() 无法识别 encoding 关键字：

df.to_clipboard(encoding='cp1252')
  File "C:\Python34\lib\site-packages\pandas\core\generic.py", line 1028, in to_clipboard
    clipboard.to_clipboard(self, excel=excel, sep=sep, **kwargs)
  File "C:\Python34\lib\site-packages\pandas\io\clipboard.py", line 95, in to_clipboard
    objstr = obj.to_string(**kwargs)
TypeError: to_string() got an unexpected keyword argument 'encoding'

有没有办法将所有数据传递到剪贴板（包括 ascii 和非 ascii）？

Answer 1

df.to_clipboard(df.to_csv(encoding='cp1252'))

只需使用指定的编码将其编码为 csv，然后将其扔到剪贴板上。
