open file with string that has multiple variables

Question

I can get the text file when I set airport to one variable. However, how can I get the text files for multiple airport codes and display the information?

airport = 'KSFO, KSJC, KOAK'

for metar in urlopen('http://weather.noaa.gov/pub/data/observations/metar/stations/%s.TXT' %airport):
        metar = metar.decode("utf-8")
        if "%s" %airport in metar:
            print metar

You need to split the string on `comma(,)` and use the individual element from the list obtained. — Rohit Jain, Oct 30 '12 at 08:19

If your goal is to fetch the weather observations for each of those airports, you could use:

from urllib import urlopen
airports = 'KSFO, KSJC, KOAK'

for airport_code in airports.split(","):
    for metar in urlopen('http://weather.noaa.gov/pub/data/observations/metar/stations/%s.TXT' % airport_code.strip()):
        metar = metar.decode("utf-8")
        print metar

For me, the output is:

2012/10/30 07:56 KSFO 300756Z 29005KT 10SM FEW001 13/11 A3006 RMK AO2 SLP178 T01280111 402110117

2012/10/30 07:53 KSJC 300753Z AUTO 00000KT 10SM CLR 10/ A3005 RMK AO2 SLP175 T0100 402060089 $

2012/10/30 08:14 KOAK 300814Z 06003KT 10SM OVC004 13/12 A3007 RMK AO2

you should indent the last two lines. – iabdalkader Oct 30 '12 at 08:28 — iabdalkader, Oct 30 '12 at 08:28

airport = 'KSFO, KSJC, KOAK'

for airports in airport.split(', '):
    for metar in urlopen('http://weather.noaa.gov/pub/data/observations/metar/stations/%s.TXT' %airports):
            metar = metar.decode("utf-8")
            if "%s" %airports in metar:
                print metar

Basiclly we split the airport variable where , (a comma and then a space) is the separator into three different variables with:

`airport.split(', ')`

It prints the first airport code but the second two don't work because there is a space in the link. – Savvis Oct 30 '12 at 08:39
