Python : List of dict, if exists increment a dict value, if not append a new dict

Question

I would like do something like that.

list_of_urls = [\'http://www.google.fr/\', \'http://www.google.fr/\', 
                \'http://www.google.cn/\', \'http         


        

Answer 1

This always works fine for me:

for url in list_of_urls:
    urls.setdefault(url, 0)
    urls[url] += 1
