I am currently defining regular expressions in order to capture parameters in a URL, as described in the tutorial. How do I access parameters from the URL as part the HttpRequest object?
My HttpRequest.GET currently returns an empty QueryDict object.
I'd like to learn how to do this without a library, so I can get to know Django better.

In a GET request, you pass parameters as part of the query string.
GET parameters (also called URL parameters or query strings) are used when a client, such as a browser, requests a particular resource from a web server using the HTTP protocol. These parameters are usually name-value pairs, separated by an equals sign = . They can be used for a variety of things, as explained below.
Any word after the question mark (?) in a URL is considered to be a parameter which can hold values. The value for the corresponding parameter is given after the symbol "equals" (=). Multiple parameters can be passed through the URL by separating them with multiple "&".
When a URL is like domain/search/?q=haha, you would use request.GET.get('q', '').
q is the parameter you want, and '' is the default value if q isn't found.
However, if you are instead just configuring your URLconf**, then your captures from the regex are passed to the function as arguments (or named arguments).
Such as:
(r'^user/(?P<username>\w{0,50})/$', views.profile_page,), Then in your views.py you would have
def profile_page(request, username): # Rest of the method If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
