Importing multilevel indexed cvs data with pandas 0.13

Question

I am trying to import CSV data with multi-indexed columns using Pandas 0.13 read_csv. The import is successful, but the resulting multi-index for the columns is surprising and not useful for me.

employment=pd.read_csv('./data/spanish/employment1976-1987thousands.csv', index_col=0,header=[7,8])

employment1976-1987thousands.csv:

The resulting columns index is

Alava                  16  19 yo          
Unnamed: 2_level_0     20  24 yo          
Unnamed: 3_level_0     25  54 yo          
Unnamed: 4_level_0     55 y over yo       
Albacete               16  19 yo          
Unnamed: 6_level_0     20  24 yo          
Unnamed: 7_level_0     25  54 yo          
Unnamed: 8_level_0     55 y over yo

and I was hoping to get it in the form

Alava    16  19 yo          
Alava    20  24 yo          
Alava    25  54 yo          
Alava    55 y over yo       
Albacete     16  19 yo          
Albacete     20  24 yo          
Albacete     25  54 yo          
Albacete    55 y over yo

Answer 1

You can do something like this to convert after the fact:

In [42]: data = """A,,B,
   ....: 1,2,1,2
   ....: 1,2,3,4
   ....: 5,6,7,8
   ....: """

In [43]: df = read_csv(StringIO(data),header=[0,1],index_col=None)

In [44]: df
Out[44]: 
   A  Unnamed: 1_level_0  B  Unnamed: 3_level_0
   1                   2  1                   2
0  1                   2  3                   4
1  5                   6  7                   8

[2 rows x 4 columns]

In [45]: df.columns = unsparsify_labels(df.columns)

In [46]: df
Out[46]: 
   A     B   
   1  2  1  2
0  1  2  3  4
1  5  6  7  8

[2 rows x 4 columns]

In [40]: def unsparsify_labels(index):
   ....:     new_labels = []
   ....:     for label in index.values:
   ....:         if label[0].startswith('Unnamed'):
   ....:             label = list(label)
   ....:             label[0] = ll
   ....:             label = tuple(label)
   ....:         else:
   ....:             ll = label[0]
   ....:         new_labels.append(label)
   ....:     return MultiIndex.from_tuples(new_labels)
   ....:
