Need help on making raycasting faster

[robie972003]

I need help making my raycaster faster as it takes time to render the image after
input. I have tried doing the turtle.tracer(0, 0) thing but it is still slow.
P.S. I don't know how to do python keyboard detection so you have to press enter every time you press a letter.

import turtle
import math

# Instructions:
# You can only type in one letter at a time and return
# w = forward
# A = left
# d = right
# s = backwards
# Do not run into the walls partly because I haven't coded the collision
# detection and also partly because it displays an error right after


screen = turtle.Screen()
screen.bgcolor("Black")
turt = turtle.Turtle()
turt.speed(0)
turt.penup()
plr = turtle.Turtle()
plr.penup()
plr.sety(-30)
plr.setx(-30)
plr.setheading(45)

draw = turtle.Turtle()
draw.penup()
draw.pensize(6)
draw.speed(0)
