•    Go

First of all, we load the main Google Search page, type search criteria into an input box and then click a search button. The click action triggers a redirect, so we wait till its end. Once the page gets loaded, we iterate over all elements in search results and assign the output to a variable. The final for loop filters out empty elements that might be because of inaccurate use of selectors.

New project is located here: https://github.com/lorien/crawler First, I've tried to use mix of asyncio (network) and classic threads (parsing HTML with lxml on multiple CPU cores) but then I've decided to use classic threads for everything for the sake of simplicity. Network requests are processed with pycurl because it is fast, feature-rich and supports socks5 proxies. You can try new framework but be aware it does not have many features yet. In particular, its options to configure network requests are very pure. If you need some option, feel free to create new issue.
