json - How to apply a variable in the url token which is of integer type using python script? -


i getting typeerror: cannot concatenate 'str' , 'int' objects when wanted customise url token "id" needed.

in place of 1 single result returned single id (say 303) want have result ids declared in variable "station" retrieved url. code follows:

import urllib2  import json    #assign url  url="http://ewodr.wodr.poznan.pl/doradztwo/swd/swd_api.php?dane={%22token%22:%22pcss%22,%22operacja%22:%22stacje%22}"    # open url   json_obj= urllib2.urlopen(str(url))  output= json.load(json_obj)   station_res= output ['data'] ['features']  item in station_res:  	station= item['id']  url1="http://ewodr.wodr.poznan.pl/doradztwo/swd/meteo_api.php?dane={%22token%22:%22pcss%22,%22id%22:}" +str(station)  	json_obj2= urllib2.urlopen(str(url1))  	output2= json.load(json_obj2)  	for item2 in output2 ['data']:  		print item2

now tried put "stations" string in "url1" still doesn't recognise url , returns error:

traceback (most recent call last):     `file "stations.py", line 23, in <module>`         `for item2 in output2 ['data']:`

keyerror: 'data'

the problem add id after '}' url looks 

   http://ewodr.wodr.poznan.pl/doradztwo/swd/meteo_api.php?dane={%22token%22:%22pcss%22,%22id%22:}331

when should 

 http://ewodr.wodr.poznan.pl/doradztwo/swd/meteo_api.php?dane={%22token%22:%22pcss%22,%22id%22:331}

so suggest :

url1 = 'http://ewodr.wodr.poznan.pl/doradztwo/swd/meteo_api.php?dane={%22token%22:%22pcss%22,%22id%22:' + str(station) + '}'

and don't need write str(url1) because string already.
