DataFrame Setup Issues

It looks like your DataFrame is not structure the way you would like it to be. Your DataFrame contains 2014 and 2015 as column header names not as row values on the used_at index. Also used_at is the index name not the index label of the first row.

You can test that this is true by executing:

import pandas as pd
from cStringIO import StringIO

text_data = '''
used_at            2014  2015
address                      
am.ru               621   273
auto.ru            1752  1595
avito.ru           5460  4631
avtomarket.ru       314   215
cars.mail.ru/sale   457   271
drom.ru            1934  1623
e1.ru              1654  1359
irr.ru/cars         619   426
'''

# Read in tabular data with used_at row as header
df = pd.read_table(StringIO(text_data), sep='\s+', index_col=0)
print 'DataFrame created with used_at row as header:'
print df
print 

# print df.used_at would cause AttributeError: 'DataFrame' object has no attribute 'used_at'
print 'df columns    :', df.columns
print 'df index name :', df.index.name
print

DataFrame created with used_at row as header:
                   2014  2015
used_at                      
address             NaN   NaN
am.ru               621   273
auto.ru            1752  1595
avito.ru           5460  4631
avtomarket.ru       314   215
cars.mail.ru/sale   457   271
drom.ru            1934  1623
e1.ru              1654  1359
irr.ru/cars         619   426

df columns    : Index([u'2014', u'2015'], dtype='object')
df index name : used_at
