can I use .split() with csv.reader?
<p>I want to create a dictionary based off of csv 1st column as key.  can i use .split() to do this or will csv.dictreader automatically base key off of 1st column?</p>

<pre><code>from collections import defaultdict
import csv
import sys

#import csv file and store in dictionary
dict=defaultdict(list)
file=csv.reader(open(‘sys.argv[1]’,‘rt’))
    for f in file:
        a,b,c,d=f.split()
        dict[a].append((b,c,d))
file.close()
</code></pre>
