url encode and decode in python3

urlcodec.py

import urllib.parse

def urlencode(str):
  return urllib.parse.quote(str)


def urldecode(str):
  return urllib.parse.unquote(str)

str = '{"name": "Kinkin"}'
encoded = urlencode(str)
print(encoded)  # '%7B%22name%22%3A%20%22Kinkin%22%7D'
decoded = urldecode(encoded)
print(decoded)  # '{"name": "Kinkin"}'

The quote() function encodes space to %20. Python also has a quote_plus() function that encodes space to plus sign (+). I've written about URL Encoding in python on my website. There is also an online URL Encoder tool.
