新人求助。关于只改变list中某个元素的问题。

family = [["the", "tall", "fat", "dad", "is", "2"],
["the", "beautiful", "mom", "is", "1"],
["son", "is", "0"]]
name = ["Bob", "Lucy", "Peter"]

复制代码

要求打印结果为

["the", "tall", "fat", "dad", "is", "Peter"],
["the", "beautiful", "mom", "is", "Lucy"],
["son", "is", "Bob"]

复制代码

要求用一函数来执行，且函数可多次执行，有一个大问题是：如果把name里的元素直接赋值到family最后一个元素中，函数就不能够二次执行了比如函数中：
for i in range(3):
family[-1] = name(int(family[-1]))
第二次在执行时已经不是数字，会报错，怎么解决这个问题？

family = [["the", "tall", "fat", "dad", "is", "2"],
["the", "beautiful", "mom", "is", "1"],
["son", "is", "0"]]
name = ["Bob", "Lucy", "Peter"]

for i in range(0,3):
family[i][-1]=name[2-i]
print family

或者使用列表生成式：
print [family[i][:-1]+[name[2-i]] for i in range(0,3)]
