tkinter做的代码雨

效果不是很好

import tkinter as tk
import random as r
t=tk.Tk()
t.title("代码雨")
size="{}x{}+{}+{}".format(t.winfo_screenwidth(),t.winfo_screenheight(),0,0)
t.config(bg="black")
t.geometry(size)
list1=[]
for i in range(50):
    a=tk.Label(text=r.choice("abcdefghijklmnopqrstuvwxyz"),font=("宋体",50),bg="black",fg="#"+str(r.randint(100000,999999)))
    a.place(x=r.randint(0,t.winfo_screenwidth()),y=r.randint(0,t.winfo_screenheight()))
    list1.append(a)
while True:
    for i in list1:
        x=i.winfo_x()
        if i.winfo_y()>t.winfo_screenheight():
            y=0
            x=r.randint(0,t.winfo_screenwidth())
        else:
            y=i.winfo_y()+3
        i.place(x=x,y=y)
        t.update()
t.mainloop()
