And as the error says lists do not have a URL attribute. You can either write a loop to return the URLs urls = [] for url in data.results: urls.append(url.URL) or more Pythonically use a List Comprehension, which combines all of that in one line: urls = [url.URL for url in data.results] In general when you want to convert a list of something to another list of something, either a subset of the original or a transformed version, like here, use a list comprehension. newlist = [f(x) for x in oldlist <if condition>] > Again, I am new to Python, so a watered-down, conceptual response to > this > would be greatly appreciated. Thanks in advance.
