1. List
list1 = ['alex','bob','lili','zhangsan']
list2 = ['1','2','3','4']
List indices start at 0
print(list1[0])

2. Rename list elements

3. Delete list elements
del list1[2]
print(list1)
Result: ['alex', 'bob', 'zhangsan']
4. List operator
print(len(list1)) #Number of list elements
Result: 4
print(list1 + list2)
Result: ['alex', 'bob', 'lili', 'zhangsan', '1', '2', '3', '4']
print(min(list2)) #minimum
Result: 1
print(max(list2)) #Maximum value
Result: 4
list1.append('jack') #Add a new object at the end of the list
print(list1)
Result: ['alex', 'bob', 'lili', 'zhangsan', 'jack']
print(list1.count('alex')) #Count the number of times an element appears in the list
