list列表元素可添加修改删除
list1=[1,'a','hh']
list1.insert(0,'cccc')#在list1 0位置插入‘cccc’
print(list1) #['cccc',1,'a','hh']插入
list1.pop(1)
print(list1)#['cccc','a','hh']删除
list1[0]='www'
print(list1)#['www','a','hh'] 修改
tuple元组一旦初始化元素不可修改
一个元素时元素后必须加逗号
tuple1=(1,)
取值方法和list几乎一致
tuple1=('a','b',[1,2])
tuple1[2][1]='x'
print(tuple1)#('a','b',[1,'x'])
嵌套list
#coding:utf-8
#buergege
# -*- coding: utf-8 -*-
L = [
['Apple', 'Google', 'Microsoft'],
['Java', 'Python', 'Ruby', 'PHP'],
['Adam', 'Bart', 'Lisa']
]
# 打印Apple:print(L[0][0])
print(L[0][0])
# 打印Python:
print(L[1][1])
# 打印Lisa:
print(L[2][2])
