Question

代码：

from __future__ import unicode_literals

#...

print df.columns
print df[u'总资产']

输出：

Index([u'余额', u'参考市值', u'可用', u'总资产', u'盈亏', u'资产(资金股份)'], dtype='object')

Traceback (most recent call last): "user_code.py", line 36, in handle_data

KeyError: u'\xe6\x80\xbb\xe8\xb5\x84\xe4\xba\xa7'

另一个版本可以正常使用。

#...

print df.columns
print df[unicode('总资产')]

----更新---------------------------------------

import pandas as pd
df = pd.DataFrame(columns=[u'总资产'])
print df.columns
print df[u'总资产']
return

输出乱码
