why won't my circle loop work in python
Question: 
    import turtle
    import time
    import random
    
    n = int(input("how many circles do you want? "))
    radius = int(input("Radius?"))
    
    turtle.forward(radius)
    turtle.left(90)
    
    for circle in range(num, 0, -1):90 (num..1)
        turtle.begin_fill()
        turtle.color(random.random(),random.random(), random.random())  
        turtle.circle(radius * circle / num)
        turtle.end_fill()
    
        turtle.left(90)
        turtle.forward(radius / num)
        turtle.right(90)
    


Answer: 
    for circle in range(num, 0, -1):90 (num..1)
    

That is not valid Python syntax. Assuming it's meant to be a comment, it would
be:

    
    
    for circle in range(num, 0, -1):     # num..1
    

However, you'll find yourself a better practitioner of the art if you remember
this: the code tells you _how_ things are done, comments tell you _why_ they
are done.

Anyone looking at Python code should already realise that loop counts down
from `num` (which should possibly be `n` by the way, or the input at the top
should assign to `num`) to `1`, else they shouldn't be _looking_ at the code.
