You misread the documentation. You need to do two things:
- Quote each key and value from your dictionary, and
- Encode those into a URL
Luckily urllib.parse.urlencode does both those things in a single step, and that's the function you should be using.
from urllib.parse import urlencode, quote_plus
payload = {'username':'administrator', 'password':'xyz'}
result = urlencode(payload, quote_via=quote_plus)
# 'password=xyz&username=administrator'

For Python 3 you could try using quote instead of quote_plus:
import urllib.parse
print(urllib.parse.quote("http://www.sample.com/", safe=""))
Result:
http%3A%2F%2Fwww.sample.com%2F
Or:
from requests.utils import requote_uri
requote_uri("http://www.sample.com/?id=123 abc")
Result:
'https://www.sample.com/?id=123%20abc'

Execution of this file takes place at the terminal via the python3 query as below. The output result is showing the encoding of a string successfully. ... In the above example, you have seen that we have used the quote() function to encode or quote a string-type variable, and it worked perfectly. On the other hand, you need to understand that we cannot apply the “urlencode” method on any string because the string cannot be encoded into any URL.

Python 3
In Python 3, the urllib package has been broken into smaller components. You'll use urllib.parse.quote_plus (note the parse child module)
import urllib.parse
safe_string = urllib.parse.quote_plus(...)
Python 2
What you're looking for is urllib.quote_plus:
safe_string = urllib.quote_plus('string_of_characters_like_these:$#@=?%^Q^$')
#Value: 'string_of_characters_like_these%3A%24%23%40%3D%3F%25%5EQ%5E%24'

Python 3
Use urllib.parse.urlencode:
>>> import urllib.parse
>>> f = { 'eventName' : 'myEvent', 'eventDescription' : 'cool event'}
>>> urllib.parse.urlencode(f)
eventName=myEvent&eventDescription=cool+event
Note that this does not do url encoding in the commonly used sense (look at the output). For that use urllib.parse.quote_plus.
Python 2
You need to pass your parameters into urllib.urlencode() as either a mapping (dict), or a sequence of 2-tuples, like:
>>> import urllib
>>> f = { 'eventName' : 'myEvent', 'eventDescription' : 'cool event'}
>>> urllib.urlencode(f)
'eventName=myEvent&eventDescription=cool+event'
