4-1比萨

pizza=['a','b','c']
for i in pizza:
    print(i)
for i in pizza:
    print('I really love '+i+'!')

4-2动物

anmimals=['dog','cat','pig']
for i in anmimals:
    print(i)
for i in anmimals:
    print('A '+i+' would make a great pet')
print('Any of these animals would make a great pet')

animals = ['dog','cat','mouse']
for i in animals:
	print("A %s would make a great pet"%i)
print("They all have four legs.")

4-3数到20

for i in range(1,21):
    print(i)

4-4一百万

numbers=list(range(1,1000001))
print(numbers)

4-5计算1-一百万的总和

numbers = list(range(1,1000001))
print(min(numbers))##求最小
print(max(numbers))#最大
print(sum(numbers))#总和

4-6奇数

bon=list(range(1, 21, 2))
print(bon)
for i in bon:
    print(i)

4-7 3的倍数

numbers = list(range(3,31,3))
for i in numbers:
    print(i)

4-8立方

a = list(range(1, 11))
for i in [i ** 3 for i in a]:
    print(i)

4-9立方解析

list = [a**3 for a in range(1,11)]
print(list)

4-10 切片

a = list(range(1, 6))
print("The first three items in the list are:")
print(a[0:3])
print("The items from the middle of the list are:")
print(a[1:4])
print("The last three items in the list are:")
print(a[-3:])

4-11你的比萨和我的比萨

mypizza = ['banana','milk','apple']
friend_pizzas = mypizza[:]
friend_pizzas.append("org")
print("my favorite pizzas are:")
for i in mypizza:
	print(i)
print("My friends favorite foods are:")
for i in friend_pizzas:
	print(i)

4-12使用多个循环

mypizza = ['banana','milk','apple']
for i in mypizza:
	print(i)

4-13自助餐

#第一个元组
yuanzu=(1,2,3,4,5)
for i in yuanzu:
    print(i)
#此处发现修改元组不大行啊
#改变元组
yuanzu=(2,3,4,5,6)
for i in yuanzu:
    print("\t",i)#为了和上面输出分开，好展示结果

4-14 PEP 8

4-15 代码审核
