I am trying to change the the pen size in Python 2.7. I know the pensize() command can be interchanged with width() (neither work), however the size of the pen stays the same no matter what value I enter. We use WingIDE to program in Python, though using the Python IDE doesn't fix the issue.

I have tested this on 3 machines, same issue. I have played with the positioning of the turtle.pensize(), size remains the same. The code below will draw the letter "I" and begin on a second letter:

import turtle



t = turtle.Pen()

turtle.bgcolor("black")

turtle.pensize(800)



t.reset()

t.color("green");



t.pu();

t.setx(-450);

t.pd();



t.left(90);



t.forward(120);



t.pu();

t.right(90);

t.forward(90);

t.right(90);

t.pd();



#I



t.forward(120);

t.left(90);

t.forward(20);



reset()

I don't really receive an error, but I will post what the WingIDE debugger displays:

First time posting here, please let me know if I can be more specific or add additional information.

And well it should as you are in fact working with two different turtles:

t = turtle.Pen()

turtle.bgcolor("black")

turtle.pensize(800)

...

t.forward(120)

You are making the mistake of mixing the functional interface to turtle with the object-oriented interface to turtle. You created your own turtle t, but you changed the pen size of the default turtle. If you want to change your turtle's pen size, you do:

t.pensize(800)

This is a common error so I recommend that Python turtle programmers use this import:

from turtle import Screen, Turtle

It loads the object-oriented code but blocks out the functional interface. Once that's fixed, then you need to address the issue raised by @jasonharper in the comments that calling reset() undoes pensize() and really isn't needed at this point in the program. Your code rewritten accordingly:

from turtle import Screen, Turtle, mainloop



screen = Screen()

screen.bgcolor('black')



t = Turtle()

t.pensize(8)



t.color("green")



t.penup()

t.setx(-450)

t.pendown()



t.left(90)

t.forward(120)



t.penup()

t.right(90)

t.forward(90)

t.right(90)

t.pendown()



t.forward(120)

t.left(90)

t.forward(20)



mainloop()  # screen.mainloop() for Python 3
