how to rotate text in python's turtle graphics

Question

I want to make diagrams with python's turtle (teaching purposes). The label "values" for the y-axis should be rotated.
Python's turtle has a method to write a string at current position:

from turtle import *
left(90) # does not help
write("values", font=('Arial', 12, 'normal'))
hideturtle()
mainloop()

"values" is still horizontal.

How can I rotate text with python's turtle?

Answer 1

It's not possible to write rotated text with turtle. See http://www.gossamer-threads.com/lists/python/bugs/879806:

Turtle is built on top of Tk, which is currently at version 8.5 - this has no ability to rotate text. When Tk version 8.6 arrives it should be able to write rotated text (see http://mail.python.org/pipermail/tkinter-discuss/2010-November/002490.html) and turtle.py could be updated to take advantage of it.

Answer 2

You CAN rotate text, but only in 8.6. Type:

pyturtle.rotate([Degrees of rotation])

Then you can do your text command. Hope this helped!
