# 高级编程技术 （week2-1） #

## 3-1 ##

names = ['Mike', 'John', 'Honda']
    for name in names:
        print(name)

## 3-2 问候语 ##

names = ['Mike', 'John', 'Honda']
    for name in names:
        print(name, ' , how do you do?')

## 3-3 自己的列表 ##

vicheles = ['by motorcycle','by walk','on foot', 'by taxi']
    for vichele in vicheles:
        print('I would like to go to school ',vichele)

## 3-4 、 3-5 ##

这两题主要使用的是列表的基本使用，列表的元素删除，还有列表元素的修改。

names = ['Mike', 'John', 'Honda']
    for name in names:
        print(name.title(), "!, would you like to have dinner with me?")
    
    busy_name = names.pop(0)
    
    print(name.title(), " is too busy to have dinner with me. It's so pity.")
    
    for name in names:
        print(name.title(), "!, would you like to have dinner with me?")

## 3-6 3-7 ##

这两道题主要练习的是python列表中的`insert()`, `append()`函数的使用。

# 接上一题的程序
    
    print("I find a big table!")
    names.insert(0, "Lily")
    names.insert(2, "Kuly")
    names.append("Xiao Ming")
    
    for name in names:
        print(name.title(), "!, would you like to have dinner with me?")
    
    print("But the new table can't get on time. Now I only can invite two friends to my dinner.")
    
    while len(names) > 2:
        delete_name = names.pop()
        print(delete_name.title(), ", I am sorry to tell you that I can't invite you to my dinner.")
    
    for name in names:
        print(name.title(), ", you still can have dinner with me!")
    
    del names[0]
    del names[0]
    
    print(names)

## 3-11 引发错误 ##

这样的程序能够引发错误

test = [1,2,3,4]
    print(test[4])

运行截图如图所示：
