from copy import copy
>>> a = [1, 2, 3]
>>> b = a[:]
>>> a is b # 1
>>> copy(a) is a # 2
>>> c = (1, 2, 3)
>>> d = c[:]
>>> e = (1, 2, 3)
>>> c is d # 3
>>> copy(c) is c # 4
>>> c is e # 5
>>> f = "ABC"
>>> g = "ABC"
>>> f is g # 6
>>> copy(f) is f # 7
>>> h = f[:]
>>> f is h # 8
答案是F F T T F T T T 你猜对了吗？
