Returning to our previous code snippet, let's assign the result of the requests.get() command to a variable, then inspect that variable. What each of those various attributes mean isn't important to figure out now, it's just enough to know that they exist as part of every request for a web resource, whether it's a webpage, image file, data file, etc. You can see this for yourself by popping open the Developer Tools (in Chrome, for OSX, the shortcut is: Command-Alt-J), clicking the Network panel, then visiting a page: But it turns out there's a lot more to getting a webpage than just getting what you see rendered in your browser. You might have expected the command to just dump the text contents of to the screen. Run this from the interactive prompt: > requests. " – is required, even though you probably never type it out in your browser. The get() method requires one argument: a web URL, e.g. Even without knowing much about HTTP, the concept of GET is about as simple as its name: it will get a resource from a web server. The get method of the requests module is the one we will use most frequently – which corresponds to how the majority of the HTTP requests your browser makes involve the GET method. Email me if you're having that issue, because it likely means you probably don't have Anaconda installed properly. ImportError, it means you don't have the requests library installed. You have to do this at the beginning of every script for which you want to use the Requests library. To bring in the Requests library into your current Python script, use the import statement: import requests Our primary library for downloading data and files from the Web will be Requests, dubbed "HTTP for Humans". It will serialize the dict as the query string: import requests resp = requests. We can pass a dict into the params argument of the get() method. The query string is: ?name=Daniel&id=123456 To fetch a URL contains a query string, e.g.: content Downloading a URL with parameters Downloading a file import requests resp = requests.
