"Turtle" module is closely related to geometry, which is also covered by "math" (and "cmath") module. Nevertheless, in many places in "turtle" the wheel is being reinvented. Currently, only π and basing trig functions are used. Performance may be improved by such refactor (for example, by using "math.hypot" instead of manual calculation of vector norm). |

Well, if you want to exploit Python features in full, I'd suggest cmath as even better library. Turtle position is just a complex numbers, and cmath has direct conversion from and to polar coordinates, which is all that's needed for basic commands. :-) |

Complex numbers to be considered, of course. My first pull request, so I'd rather not make such a revolution this time. :) |

You could post a suggested replacement for a couple of the expressions, with the warning that we would not necessarily use it. math.hypot has recently be worked over so that it is perhaps more accurate than the standard C version. |
