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])
