Move the turtle forward by the specified distance, in the direction the The Python turtle library is a library that provides programmers with a virtual canvas to create shapes and images. It is beneficial to the children and for the experienced programmer because it allows designing unique shapes, attractive pictures, and various games. While this function can still be used to draw a regular polygon with 20 or fewer sides, it is better to use the regularPolygon() turtle method to take advantage of svg commands. Keeping consistent with the original ColabTurtle, the non-zero speed values can be from 1 to 13 (slowest to fastest).
