Tianyi Zheng 9f041e9cc8 Refactor sierpinski_triangle.py (#8068) ... * updating DIRECTORY.md * Update sierpinski_triangle.py header doc * Remove unused PROGNAME var in sierpinski_triangle.py The PROGNAME var was used to print an image description in the reference code that this implementation was taken from, but it's entirely unused here * Refactor triangle() function to not use list of vertices Since the number of vertices is always fixed at 3, there's no need to pass in the vertices as a list, and it's clearer to give the vertices distinct names rather than index them from the list * Refactor sierpinski_triangle.py to use tuples Tuples make more sense than lists for storing coordinate pairs * Flip if-statement condition in sierpinski_triangle.py to avoid nesting * Add type hints to sierpinski_triangle.py * Add doctests to sierpinski_triangle.py * Fix return types in doctests * Update fractals/sierpinski_triangle.py Co-authored-by: github-actions <${GITHUB_ACTOR}@users.noreply.github.com> Co-authored-by: Christian Clauss <cclauss@me.com>		2023-01-02 14:15:14 +01:00
