import copy

a=[1,2,3,4,['a','b']] ?#原始對(duì)象

b=a ?#賦值，傳對(duì)象的引用

c=copy.copy(a) ?#對(duì)象拷貝，淺拷貝

d=copy.deepcopy(a) ?#對(duì)象拷貝，深拷貝

a.append(5) ? #修改對(duì)象a

a[4].append('c') ? #修改對(duì)象a中的['a', 'b']數(shù)組對(duì)象

print('a =',a)

print('b =',b)

print('c =',c)

print('d =',d)

以上實(shí)例執(zhí)行輸出結(jié)果為：

('a = ',[1,2,3,4,['a','b','c'],5])

('b = ',[1,2,3,4,['a','b','c'],5])

('c = ',[1,2,3,4,['a','b','c']])

('d = ',[1,2,3,4,['a','b']])
