[Python Project] Christmas is coming soon, there are several Christmas tree effects implemented by Python based on turtle | Source code attached

Preface

halo, good morning, buns
Christmas is coming
Today my good brothers have arranged a wave of Christmas Python codes a>
It is mainly realized using turtle drawing, it is very simple
Without further ado, let’s start directly
