What am I doing wrong with csv.reader?

I'm trying to write a python script which reads data from one csv file and based on that data it picks up the data from another csv file and writes it in third csv. However, the csv.reader() doesn't seem to work. It always returns

<_csv.reader object at 0x7f1d7150ce50>
<_csv.reader object="" at="" 0x7f1d714c8b40="">

I tried using fseek(0) also. But even that doesn't work. What am I doing wrong?
Here's the entire code.

__author__ = 'sudarshini'
import csv, os
pattern="new"
good=[]
i=0
j=0
for path, dirs, files in os.walk("/home/sudarshini/Downloads/train"):
        for filename in files:
                if pattern in filename:
                        good[:]=[]
                        with open(filename,'r') as f:
                                f.seek(0)
                                print f
                                reader1=csv.reader(f)
                                lol=list(reader1)
                                pattern2 = lol[1]
                                actual=pattern2[0]
                                oho=actual[0:14]
                                print oho
                                print reader1
                                i=0
                                for path, dirs, files in os.walk("/home/sudarshini/Downloads/train"):
                                        for fa in files:
                                                if oho in fa:
