python：窗口化和制作图形

#圆
from tkinter import * canvas = Canvas(width=800, height=600, bg='yellow')#声明窗口属性
canvas.pack(expand=YES, fill=BOTH) k = 1 j = 1
for i in range(0, 26): canvas.create_oval(310 - k, 250 - k, 310 + k, 250 + k, width=1)#画圆
    k += j j += 1 mainloop()#执行整个函数

执行结果：

#直线
from tkinter import * canvas =Canvas(width=300,height=300,bg='white')#声明窗口属性
canvas.pack(expand=YES,fill=BOTH)#执行窗口属性
x0 = 260#声明坐标
y0 = 260 y1 = 90
for i in range(10): canvas.create_line(x0,y0,x0,y1, width=1, fill='red')#画直线
        x0 = x0 - 5 y0 = y0 - 5 y1 = y1 + 5 mainloop()#执行整个函数

执行结果：

#矩形
from tkinter import * canvas =Canvas(width=300,height=300,bg='white')#声明窗口属性
canvas.pack(expand=YES,fill=BOTH)#执行窗口属性
x0 = 263 y0 = 263 y1 = 275 x1 = 275
for i in range(19): canvas.create_rectangle(x0, y0, x1, y1) x0 -= 5 y0 -= 5 x1 += 5 y1 += 5 mainloop()
