Does anyone know how the variables label and scale are recognized
without a global statement or parameter, in the function resize() in
this code:
#!/usr/bin/env python
from Tkinter import *
def resize(ev=None):
label.config(font='Helvetica -%d bold' % \
scale.get())
top = Tk()
top.geometry('250x150')
label = Label(top, text='Hello World!',
font='Helvetica -12 bold')
label.pack(fill=Y, expand=1)
scale = Scale(top, from_=10, to=40,
orient=HORIZONTAL, command=resize)
scale.set(12)
scale.pack(fill=X, expand=1)
quit = Button(top, text='QUIT',
command=top.quit, activeforeground='white',
activebackground='red')
quit.pack()
mainloop()
