Hello everyone,

I to had the same problem and it pestered me to the nth degree. I had that
many problems I went to the python site and copied an example and used that
to test why it wasn't working -see below example and traceback report. I
wasted a lot of time trying to figure my issue out. Then it dawned on me - I
had called the main program csv.py. But even when I changed the name of the
file and ran the program I was still getting the same problem. Why? because
I had in the directory a file called csv.py which is exactly the file name
for the csv file that is used in the import function. I deleted all the
references of csv.py from the directory that I was executing the command
from. Magically it worked. I do feel stupid but I hope this helps others who
maybe experiencing the same issue. Check for erroneous version of files that
are called cvs.py. 

import csv
reader = csv.reader(open("test.csv", "rb"))
for row in reader:
    print row

Traceback (most recent call last):
  File "H:/csv.py", line 1, in <module>
    import csv
  File "H:/csv.py", line 2, in <module>
    reader=csv.reader(open(test.csv, "rb"))
AttributeError: 'module' object has no attribute 'reader'
