Question

i just installed python

i am trying to run this script:

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

i am running on windows.

1. do i have to type each line individually into python shell or can i save this code into a text file and then run it from the shell?
2. where does some.csv have to be in order to run it? in the same c:\python26 folder?
3. what is this code supposed to do?

Answer 1

1. You can do both! To run the code from a text file (such as ‘csvread.py’, but the extension doesn’t matter), type: python csvread.py at the command prompt. Make sure your PATH is set to include the Python installation directory.

2. “some.csv” needs to be in the current directory.

3. This code opens a Python file descriptor specifically designed to read CSVs. The reader file descriptor then prints out each row of the CSV in order. Check the documentation out for a more detailed example: http://docs.python.org/library/csv.html
