printing out dictionary values after filtering through it
<p>I need to be able to print out the correct zipcodes that meet the thresh hold criteria, i can filter through them and operate on them, but the last step is to print which zipcodes are within 50miles of the center one.
here is my code</p>

<pre><code>import sys
import csv
import math


dicts = {}
origin =[]
#methods to convert to radians
def getLatRad(latitude):
    return float(latitude) * (math.pi/180.0)
def getLongRad(longitude):
    return float(longitude) * (math.pi/180.0)
#method to find which zipcodes are within thresh
def getnearbylist(center, thresh, ziplist):
    try:
        f = open("zips.csv")
        csvParser = csv.reader(f)
        for row in csvParser:
            zipcode= row[0].strip()
            latitude= row[2].replace('"', '').strip()
            longitude=row[3].replace('"', '').strip()
            dicts[zipcode] = {'zipcode':zipcode,'latitude': latitude, 'longitude':longitude}
        if center in dicts:
            origin=dicts[center]
            longRad2= getLongRad(origin['longitude'])
            latRad2= getLatRad(origin['latitude'])
        matched = {match: dicts[match] for match in ziplist if match in dicts}
        for x in matched:
            longRad1= getLongRad(matched[x]['longitude'])
            latRad1= getLatRad(matched[x]['latitude'])
            dlon = longRad2 - longRad1 
            dlat = latRad2 - latRad1
            a = math.sin(dlat/2)**2 + math.cos(latRad1) * math.cos(latRad2) * math.sin(dlon/2)**2
            c = 2 * math.asin(math.sqrt(a)) 
            m = 3960 * c
            if m &lt;thresh: # cant figure out how to return zipcodes instead of m value
                print m

    except ValueError:
        pass
def main():
    center = '12601'  # Our center zipcode
    thresh = 50  # We are looking for zipcodes within 50 miles
    ziplist = ['12481', '10001', '12203', '10303', '12561'] # Our test list

    nearbylist = getnearbylist(center, thresh, ziplist) # Call the function
    print nearbylist

if __name__ == '__main__':
    main()
</code></pre>

<p>so instead of printing m, i want to return the zipcodes
thanks!</p>
