Question

What’s the best way to exclude parameters from request.GET?

eg, given a url param ?a=a&b=b&c=c and I want to take out param b to generate url param to ?a=a&c=c without changing request.GET

Right now I am looping through the keys to take out b

params = {}
for key,value in request.GET.items():
  if not key == 'b':
    params[key] = value

url = urllib.urlencode(params)

I am wondering if there is a better, more elegant way to achieve the same result? eg.

request.GET.urlencode(exclude=['b',])

or even this, better

urllib.urlencode(request.GET.exclude('b'...)

Answer 1

This should work:

get = request.GET.copy()
del get['b']

params = urllib.urlencode(get)
