how to handling time series data file with Python?

[aupres]

I am a newbie in deep learning and try to make feature matrix with python. My sample data structure is like below,

dataset.csv

State   Earnings   Hispanic   Indian   Asian   Black   White   people_in_poverty

Alabama   0.2        0.4        0.6     0.6      0.2    0.8          a.csv
Florida   0.5        0.6        0.4     0.1      0.6    0.7          b.csv
Kentucky  0.7        0.7        0.9     0.8      0.3    0.6          c.csv
Minnesota 0.3        0.1        0.2     0.5      0.2    0.7          d.csv
....

The column names [Earnings, Hispanic, Indian, Asian, Black, White] are the attributes and people_in_poverty is the class of feature matrix. When the value of people_in_poverty is numeric, the python codes are simple.

people_in_poverty
0.7
0.3
0.2
0.6

import pandas as pd
df = pd.read_csv('dataset.csv', names=['state', 'Earnings', 'Hispanic', 'Indian', 'Asian', 'Black', 'White', 'people_in_poverty'])
dataset = df.values

However, in my case, the class of feature matrix has csv file which includes the times series data.

people_in_poverty
a.csv
b.csv
c.csv
d.csv

a.csv
2010-08-27        0.2
2010-09-27        0.7
2010-10-27        0.6
2010-11-27        0.9
2010-12-27        0.4
2011-01-27        0.8
2011-02-27        0.5
2011-03-27        0.3

Then I want to know how to modify my pd.read_csv() python codes. The class of the feature matrix is not the numeric value, but csv file containing the time series values. Any advice is needed. Thanks in advanced.
