Python 练习实例63
Python 100例题目：画椭圆。
程序分析：使用 Tkinter。
程序源代码：
实例
#!/usr/bin/python
# -*- coding: UTF-8 -*- if __name__ == ‘__main__‘:
from Tkinter import *
x = 360
y = 160
top = y – 30
bottom = y – 30
for i in range(20):
canvas.create_oval(250 – top,250 – bottom,250 + top,250 + bottom)
top -= 5
bottom += 5
canvas.pack()
mainloop()
# -*- coding: UTF-8 -*- if __name__ == ‘__main__‘:
from Tkinter import *
x = 360
y = 160
top = y – 30
bottom = y – 30
canvas = Canvas(width = 400,height = 600,bg = ‘white‘)
for i in range(20):
canvas.create_oval(250 – top,250 – bottom,250 + top,250 + bottom)
top -= 5
bottom += 5
canvas.pack()
mainloop()
以上实例输出结果为：
