Python - special characters reading from URL parameter

Question

I am reading URL parameter from the below URL

http://exaple.com/api/v1/get_example/?fruits_name=[apple%20+%20banana]

fruits = urllib.unquote(request.GET.get('fruits_name', None)).decode('utf8')
    print fruits

my output is: [apple banana] in between apple and banana I am getting three spaces but not + symbol in my output. the original string is [apple + banana]. I need output as [apple + banana].

Can anyone suggest where I am doing wrong??

@Jordan Singer my urls.py file is url(r'^api/v1/get_example/$', views.get_example,name='get_example'), and views.py is @api_view(['GET']) def get_example(request): fruits = urllib.unquote(request.GET.get('fruits_name', none)).decode('utf8') print fruits — user3202086

Why do have the spaces quoted (%20) but not the plus sign (%2B) ? In a quoted URL, a plus sign is unquoted to a 'space', that's why you end up with 3 spaces. — Maurice Meyer

You probably need to use %2B

Ex:

http://exaple.com/api/v1/get_example/?fruits_name=[apple%20%2B%20banana]

You could split query string on your own to preserve the plus sign:

from urllib.parse import urlparse, unquote

u = 'http://exaple.com/api/v1/get_example/?fruits_name=[apple%20+%20banana]'

o = urlparse(u)
qs = unquote(o.query)

queryDict = {k: v for (k, v) in [x.split("=", 1) for x in qs.split("&")]}
print(queryDict)

Prints:

{'fruits_name': '[apple + banana]'}

Replace special characters in string using the %xx escape. Letters, digits, and the characters '_.-' are never quoted. By default, this function is intended for quoting the path section of the URL.The optional safe parameter specifies additional characters that should not be quoted — its default value is '/'
