Trying to draw Kenyan flag colours in python, encountered name error?-CodePudding

I thought trying to draw this thing in kenyan colours. Thought it would be simple and quick but ran into errors on the second line.

import turtle pen=turtle.Turtle() pen.speed('fastest')

When I take out the second line the error appears on the third line.

What am I doing wrong?

turtle.bgcolor('black')
col=('black','white','red','white','green')

That's what I'm trying to get to.

Any help would be greatly appreciated.

I'd like to ask a few questions but don't have the reputation, so I'll take the best shot I can to help out with the info given.

I've never used turtle myself, but after looking online I found this section of code which compiles:

from turtle import *

color('red', 'yellow')
begin_fill()
while True:
    forward(200)
    left(170)
    if abs(pos()) < 1:
        break
end_fill()
done()

From that I think your issue is how you are importing. Try importing turtle the same way as above, and then do:

color('black','white','red','white','green')

instead of

col=('black','white','red','white','green')

If that doesn't fix the issue you may be using a different library called turtlePen or something similar, but I couldn't find anything on that. It would help if you add the error message your getting, and enough code to compile and test myself.

Looking at your code, let me know if I misinterpreted where white space should be.

from turtle import * 
pen=turtle.Turtle() 
pen.speed('fastest') 
turtle.bgcolor('black') 
color=('black','white','red','white','green')  
for i in range(1,200,2):   
    t.pencolor(col[i%4])   
    for x in range(0,10):     
        t.circle(i)     
        t.rt(50)      
turtle.done()

Your issue isn't the import it's the use of t. instead of pen. New code should look like this:

import turtle 
pen=turtle.Turtle() 
pen.speed('fastest') 
turtle.bgcolor('black') 
color=('black','white','red','white','green')  
for i in range(1,200,1):   
    pen.pencolor(color[i%4])   
    for x in range(0,10):     
        pen.circle(i)     
        pen.rt(50)      
turtle.done()

~~The colors don't seem to work tho. I'll look into it a bit more in a few minutes.~~

note the for loop should iterate by 1 not 2 for the colors to switch properly.
