关于list， 增加，插入，查找，删除，切片等，代码注释如下：
names = ["James","Jasmine", "Wade","Harden","Paul","Curry"]
#print(names)
names.append("Durant") #列表末尾加 Durant
names.insert(3,"love") #列表位置3的名字插入名字 love
names[1] = "Roay" #列表位置1的名字 Jasmine改成 Roay
print(names)
print(names[2:-1]) #切片
# delete
names.remove("Harden") # 2 ways to delete identify name
del names[0]
print(names)
names.pop() #默认删除最后一个/remove and return item at index(default last)/ 输入下表后等于del names[0]
print(names)
print(names.index("love")) #已知名字，查找名字所在位置
names.insert(4,"Curry")
print(names.count("Curry")) #统计list里面有多少个 Curry
console 编译出结果则是：
[‘James‘, ‘Roay‘, ‘Wade‘, ‘love‘, ‘Harden‘, ‘Paul‘, ‘Curry‘, ‘Durant‘]
[‘Wade‘, ‘love‘, ‘Harden‘, ‘Paul‘, ‘Curry‘]
[‘Roay‘, ‘Wade‘, ‘love‘, ‘Paul‘, ‘Curry‘, ‘Durant‘]
[‘Roay‘, ‘Wade‘, ‘love‘, ‘Paul‘, ‘Curry‘]
