python turtle rotate
import turtle
t = turtle.Turtle()
# When using t.setheading(), angles start with 0 degrees, which points right.
# It then goes anti-clockwise, with 90 degrees being up, 180 being left
# and 270 degrees being down. 360 degrees is back at the start, and thus
# is the same as 0 degrees. For Example:
t.setheading(45) # Face the top-right
# You can also use t.seth()
t.seth(180) # Face leftwards
# If you want to rotate your turtle relative to its current position,
# for example you want it to do a 90 degree left turn you can use
# t.left() and t.right(). Positive values will turn the turtle however many
# degrees in the direction of the function you're using, whereas negative values
# would be the equivelent of using the opposite function:
t.left(90) # Quarter-turn left
t.right(-90) # Also quarter-turn left
# You can also use the shorthand functions t.lt() and t.rt()
t.lt(180) # Face the opposite direction to where the turtle is currently looking
t.rt(180) # Does exactly the same thing
# If you want to use radians you can use the t.radians() function:
t.radians()
# this can be reverted by using:
t.degrees()
