#!/usr/bin/env python3

classmates = ['Michael','Bob','Tracy']
print('classmates is:',classmates)
print('len is',len(classmates))
print('classmates[0] is',classmates[0])
print('classmates[-1] is',classmates[-1])

classmates.append('Adam')
print('classmates is:',classmates)
classmates.insert(1,'Jack')
print('classmates is:',classmates)

print('pop:',classmates.pop())
print('classmates is:',classmates)

print('pop:',classmates.pop(1))
print('classmates is:',classmates)


classmates[1] = 'Sarah'
print('classmates is:',classmates)


L = [
    ['Apple', 'Google', 'Microsoft'],
    ['Java', 'Python', 'Ruby', 'PHP'],
    ['Adam', 'Bart', 'Lisa']
]


print(L[0][0])
print(L[1][1])
print(L[2][2])


#This is tuple below:
#变的是list,不变得是tuple中的指向

t = ('a', 'b', ['A', 'B'])
t[2][0] = 'X'
t[2][1] = 'Y'
print(t)
