我不确定我是否通过传递函数参数的对象样式理解Python调用的概念(在此处解释http://effbot.org/zone/call-by-object.htm).似乎没有足够的例子来澄清这个概念(或者我的google-fu可能很弱!:D)

我写了这个有点人为的Python程序,试图理解这个概念

def foo( itnumber, ittuple,  itlist, itdict   ):
    itnumber +=1 
    print id(itnumber) , itnumber 

    print id(ittuple)  , ittuple

    itlist.append(3.4)
    print id(itlist)   , itlist

    itdict['mary']  = 2.3
    print id(itdict),    itdict



# Initialize a number, a tuple, a list and a dictionary
tnumber = 1
print id( tnumber ), tnumber 

ttuple  = (1, 2, 3)
print id( ttuple ) , ttuple

tlist   = [1, 2, 3]
print id( tlist ) , tlist

tdict = tel = {'jack': 4098, 'sape': …
