Choice Function: Replaced sample with choice for selecting a single random item from a sequence. This simplifies the code when only one random choice is needed.

Pen State Functions: Corrected the function names from pu and pd to penup and pendown, respectively, for clarity and consistency.

Position Copy: Used the copy() method to create a copy of the position vector before modifying it. This prevents unintended changes to the original position vector.

Distance Calculation: Replaced abs(tt.pos() - start_position) with tt.distance(start_position) to calculate the distance between two points more accurately.

Indentation and Formatting: Ensured consistent indentation and formatting throughout the code for readability and maintainability.
