Using a variable to replace an integer? (Except it isn't working!)

[s1monsays]

So I'm trying to use the yweather module, but replacing the way it goes about getting the woeid with a system of variables so that I can A. use it wherever and not have to input a new woeid, and B. automate the whole thing. I'm super new to python but I feel like this shouldn't be this difficult, here's my code:

#note: the url is actually there in the code, but it was preventing me from posting this
url = 'freegeoip'
try:
     with closing(urlopen(url)) as response:
           location = json.loads(response.read())
           loc_c = location['city']
           loc_s = location['region_name']
except:
           print('step 1 failed')

client = yweather.Client()
wid = client.fetch_woeid('loc_c, loc_s')
print(wid)
print('steps 1 and 2 finished')

print('step 3 started')
loc_weather = client.fetch_weather('wid')
loc_weather["condition"]["text"]
loc_weather["condition"]["temp"]
print('step 3 finished')

The whole thing works just fine, up until "loc_weather...('wid')". Then it just stops, I think? It doesn't give me an error message in the terminal or anything, it just stops firing I think. It works fine when I put in the actual woe id it wants, but that isn't going to work if I'm in a new place / using an automated script. Any help would be appreciated! Sorry if this is a dumb question, I'm super new to python.
