I was trying to get some results over small data before putting heavy data, code
seems giving desired output, as in 

The name of files are: ['C:\\Python27\\TestDoc\\TestDoc1.txt', 'C:\\Python27\\TestDoc\\TestDoc2.txt', 'C:\\Python27\\TestDoc\\TestDoc3.txt', 'C:\\Python27\\TestDoc\\TestDoc4.txt']
C:\Python27\TestDoc\TestDoc1.txt []
C:\Python27\TestDoc\TestDoc2.txt []
C:\Python27\TestDoc\TestDoc3.txt []
C:\Python27\TestDoc\TestDoc4.txt []
The Contents of file in list of lists: [['There is a home.'], ['One man lives there.'], ['He is tall.'], ['He is good.']]

I am trying to put heavy files with big contents, so was getting confused whether I was going fine. But the way I am creating lists may there be a a better way?

Subhabrata Banerjee.
