from tkinter import Canvas,Tkdef use_rgb(rgb):rgb = str(rgb)RGB = place('(', '').replace(")", '').split(',')color = '#'for i in RGB:num = int(i)# 将R、G、B分别转化为16进制拼接转换并大写 hex() 函数用于将10进制整数转换成16进制，以字符串形式表示color += str(hex(num))[-2:].replace('x', '0')return colortop = Tk()
canvas = Canvas(top,width=1000,height=800,bg="#000000")
canvas.pack()
n=100    # 粒子横坐标
size = 10    # 粒子大小
rgb2 = (0,0,0)
rgb1 = (255,255,128)
a1, a2, a3, b1, b2, b3 = rgb1[0], rgb1[1], rgb1[2], rgb2[0], rgb2[1], rgb2[2]
r, g, b = (b1 - a1), (b2 - a2), (b3 - a3)
for i in range(size):x1 = 100 + iy1 = 100t = (x1 - 100) / sizergb = (int(a1 + r * t), int(a2 + g * t), int(a3 + b * t))ate_oval(n-i,n-i,n+i,n+i,width=2,outline=use_rgb(rgb))top.mainloop()

从亮黄色渐变到背景色，不断的画圆，并计算圆的颜色
