Question

编辑：问题与unicode无关

我有带有unicode名称的列，例如“＃前田敦子：日本”。我想从我的数据框中删除这些内容，但我得到的是UnicodeEncodeError：

此代码

for title_loc in f_df.columns:
    if 'Japan' in title_loc:
        f_df.drop(title_loc)

发出此错误

  File "timeseries/sum_japan_timeseries.py", line 25, in read_timeseries_dir
    f_df.drop(title_loc)
  File "/home/isl/rfcompton/.local/lib/python2.7/site-packages/pandas/core/generic.py", line 1401, in drop
    new_axis = axis.drop(labels)
  File "/home/isl/rfcompton/.local/lib/python2.7/site-packages/pandas/core/index.py", line 1623, in drop
    raise ValueError('labels %s not contained in axis' % labels[mask])

    separator, prefix)

    _summaryEdgeItems, summary_insert)[:-1]

    word = format_function(a[-1])
UnicodeEncodeError: 'ascii' codec can't encode characters in position 1-3: ordinal not in range(128)

当列名没有unicode，任何想法时，我可以.drop就好了吗？

Answer 1

这里有一些问题。默认情况下，drop对行而不是列进行操作。此外，默认情况下，它返回一个新对象，并且不会修改原始对象。问题可能是由于它试图打印出剩余的列，其中一些列还包含不可显示的Unicode。

使用unicode名称删除pandas列
