@Hope, you’re right, json.loads() works in your example, though I’m not sure how the object_hook option works or if it would even be necessary. This should do what your asking: import urllib, json url=”https://en.wikipedia.org/w/api.php?action=query&format=json&prop=langlinks&list=&titles=tallinn&lllimit=10″ response = urllib.urlopen(url) data = json.loads(response.read()) print data[‘continue’][‘llcontinue’] output:31577|bat-smg With this you should be able to get the language values you’re … Read more

As the commenter points out you’re treating the list like a dictionary, instead this will select the name fields from the dictionaries in the list: list((item[‘fields’][‘components’][i][‘name’] for i, v in enumerate(item[‘fields’][‘components’]))) Or simply: [d[‘name’] for d in item[‘fields’][‘components’]] You’d then need to apply the above to all the items in the iterable. EDIT: Full solution … Read more

The most analagous way to do it the way you describe it would be to use two variables left (l) and right (r) that will iterate the string and get their base values using ord(char) – ord(‘a’) + 1: my_string = “World” my_string = my_string.lower() l = 0 r = len(my_string)-1 total = 0 while … Read more
