Python actual combat-automatically generate Valentine's Day confession roses, love for girlfriend, and draw a cherry blossom tree with Python. May Wuhan blossom together!

March is approaching, and the cherry blossom season is coming again. Today’s skill post wants to teach everyone to draw a cherry blossom tree with Python, and give it to friends who are in Wuhan or want to go to Wuhan, when the cherry blossoms are not in bloom. , We enjoy the cherry blossoms online, when the cherry blossoms are in full bloom, we will meet at the foot of Luojia Mountain!
I hope that not only the cherry blossoms will be here, but also you who will be safe after the epidemic!
