I want to place the menu on the bottom (menuFrame.pack(side=BOTTOM,
fill=X)). But it does not work. Why?

step1: I first create a widget "menuFrame" which is belong to the
rootWin
...menuFrame = Frame(self.rootWin)
step2: then I put the widget to the bottom of the rootWin
...menuFrame.pack(side=BOTTOM, fill=X)
step3: I create a menu belong to the menuFrame.
...menuBar = Menu(menuFrame, tearoff=1)
since menuFrame should be placed to the bottom, so does the menuBar in
my opinion. What the problem is?

what's the difference between f(a) and f(*a)

[qxyuestc]

def sum1(*a): return(sum(i*i for i in a))
def sum2(a): return(sum(i*i for i in a))

a=[1,2,3]
print(sum1(*a), sum2(a))

showed above: the result from sum1() and sum2() is the same. So, what
is the difference between f(a) and f(*a)
