Here's a question for Python

import turtle
t = turtle.Turtle()
t.shape("turtle")
while True:
    t.penup() 
    t.goto(300, 0) 
    t.write("If the turtle comes here, it's a positive number.")
    t.goto(0, 300)
    t.write("If the turtle comes here, it's 0."")
    t.goto(-300, 0)
    t.write("If the turtle comes here, it's negative.")
    t.goto(0, 0) 
    t.pendown() 
    n = turtle.textinput("", enter a number: ")
    #s = int(n)
    if( n == 'a' ):
        break
    elif( int(n) > 0 ):
        t.goto(300, 0)
    elif( int(n) == 0 ):
        t.goto(0, 300)
    elif( int(n) <= 0):
        t.goto(-300, 0)
    elif( n == 'b' ):
        break    
    t.clear()

I understand that when the variable n is entered as input, it is received as a string. If you receive a positive, zero, or negative number with an infinite loop, draw a line and try to end when you receive 'a', 'b'.

I don't know much about the module, but just looking at the loop, I think we need to fix it like this.

import turtle
t = turtle.Turtle()
t.shape("turtle")

t.penup() 
t.goto(300, 0) 
t.write("If the turtle comes here, it's a positive number.")
t.goto(0, 300)
t.write("If the turtle comes here, it's 0."")
t.goto(-300, 0)
t.write("If the turtle comes here, it's negative.")
t.goto(0, 0) 
t.pendown() 

#s = int(n)

while True:
    n = turtle.textinput("", enter a number: ")
    if( n == 'a' ):
        break
    elif( int(n) > 0 ):
        t.goto(300, 0)
    elif( int(n) == 0 ):
        t.goto(0, 300)
    elif( int(n) <= 0):
        t.goto(-300, 0)
    elif( n == 'b' ):
        break    
t.clear()
