How to draw different varieties of cherry trees based on python implementation

This article mainly introduces how to realize the painting of different varieties of cherry trees based on python, the text through the sample code is very detailed, for everyone's learning or work has a certain reference learning value, need to friends can refer to the next!

Dynamically generated cherry blossoms

Rendering (this one is dynamic):

Implementation Code:

import turtle as T
import random
import time

# Drawing cherry blossom torsos (60,t) #
def Tree(branch, t):
  (0.0005)
  if branch > 3:
    if 8 <= branch <= 12:
      if (0, 2) == 0:
        ('snow') # White
      else:
        ('lightcoral') # Light coral
      (branch / 3)
    elif branch < 8:
      if (0, 1) == 0:
        ('snow')
      else:
        ('lightcoral') # Light coral
      (branch / 2)
    else:
      ('sienna') # Ochre (zhě) color
      (branch / 10) # 6
    (branch)
    a = 1.5 * ()
    (20 * a)
    b = 1.5 * ()
    Tree(branch - 10 * b, t)
    (40 * a)
    Tree(branch - 10 * b, t)
    (20 * a)
    ()
    (branch)
    ()

# Falling petals
def Petal(m, t):
  for i in range(m):
    a = 200 - 400 * ()
    b = 10 - 20 * ()
    ()
    (b)
    (90)
    (a)
    ()
    ('lightcoral') # Light coral
    (1)
    ()
    (a)
    (90)
    (b)

# Drawing area
