I'll visit that channel when back from vacation for sure. To do what you want you could use list comprehensions or the filter(function, sequence) function: List comprehension: links = ["https://securesite.com", "http://unsecuresite.com", "https://sec2.com", "http://unsec2.com"] [url for url in links if not url.startswith("https")] >>> ['http://unsecuresite.com', 'http://unsec2.com'] filter() + lambda: links = ["https://securesite.com", "http://unsecuresite.com", "https://sec2.com", "http://unsec2.com"] filter(lambda url: not url.startswith("https"), links) ['http://unsecuresite.com', 'http://unsec2.com'] I'd go with the list comprehension, from your use of map i'd guess you'd go with the filter ;) Of course you'd replace the url.startswith with whatever your criteria is.
