Random Turtle Movement.

I use turtle module, the standard module, in Python.

The turtle movement has random direction (angle), and random distance (forward/backward).

import turtle
from random import uniform

for i in range (1,100):
    #random angle
    a = uniform (-90,90)
    #random move
    d = uniform (-100,100)

The Power of 10

Rules for Developing Safety-Critical Code:

Avoid complex flow constructs, such as goto and recursion.

All loops must have fixed bounds. This prevents runaway code.

Avoid heap memory allocation.

Restrict functions to a single printed page.

Use a minimum of two runtime assertions per function.

Restrict the scope of data to the smallest possible.

Check the return value of all non-void functions, or cast to void to indicate the return value is useless.

Use the preprocessor sparingly.

Limit pointer use to a single dereference, and do not use function pointers.

Compile with all possible warnings active; all warnings should then be addressed before release of the software.
