TypeError: writable() takes 1 positional argument but 2 were given

Question

I'm doing some udemy course and in one lesson there was an example with small and "easy" web application written in Python. Of course I retyped this code to my Visual studio code, but I'm receiving some errors.

My goal is to receive output in console when I'm refreshing my "web page" in the browser. I'm using this code on my own PC, so the URL which I'm using is: http://localhost:5000/ <--- and it is fine.

Actually, when I'm refreshing the web browser, I'm receiving this error:

----------------------------------------
127.0.0.1 - - [24/Oct/2022 20:37:55] "GET /favicon.ico HTTP/1.1" 200 -

TypeError: writable() takes 1 positional argument but 2 were given
----------------------------------------

My code which i retyped from the course:

from asyncio import Handle
import http.server


class HandleRequests(http.server.BaseHTTPRequestHandler):

    def do_GET(self):
        self.send_response(200)
        self.send_header("Content-type", "text/html")
        self.end_headers()
        self.wfile.writable(bytes("<html><head><title>First application</title></head><body style='color: #333; margin-top: 30px;'><center><h2>Welcome to our first prometheus-python application.</center></h2></body></html>","utf-8"))
        self.wfile.close

if __name__ == "__main__":
    server = http.server.HTTPServer(('localhost', 5000), HandleRequests)
    server.serve_forever()

Can You show me where I'm making a mistake ? For now, I'm very big newbie in coding, I just want to run this web application to learn next things from my course.

writable only takes the self (implicit first argument on method calls). Maybe you want to call another method like `write`? Try to consider what the API designers would have wanted to express. `writable` with a string argument does not make sense, it makes sense for it to be a method `() -> bool` — DownloadPizza, Oct 24 '22 at 18:56
It works when i changed writeable to write. I dont know why author of the course used it and it works for him. I just retyped all :( His Python version is also the same as mine. Thank you @DownloadPizza :) Today I will eat a pizza for you :) — seroslaw, Oct 24 '22 at 19:12
