File exists but Python says 'not found'.

[prerit86 at gmail.com]

I'm running this code that reads 2 csv files (one of them is train.csv). The code gives an error saying 'file not does not exist'. However, the file does exists in the same location as the .py file. Can someone please help me on this. Thanks!
