4.2 动手试一试

4-1 比萨：想出至少三种你喜欢的比萨，将其名称存储在一个列表中，在使用for循环将每种比萨的名称都打印出来。

修改这个for循环，使其打印包含比萨名称的句子，而不仅仅是比萨的名称。对于每种比萨，都显示一行输出，如" I like pepperoni pizza"

在程序末尾添加一行代码，它不在for循环中，指出你有多喜欢比萨。输出应包含针对每种比萨的消息，还有一个总结性句子，如“I really love pizza!”

lists = ['xiaweiyi', 'xiangchang', 'liulian']
for list in lists:
     print(list)

xiaweiyi
xiangchang
liulian

lists = ['xiaweiyi', 'xiangchang', 'liulian']
for list in lists:
     print(list)
     print("I like pepperoni pizza")

xiaweiyi
I like pepperoni pizza
xiangchang
I like pepperoni pizza
liulian
I like pepperoni pizza

lists = ['xiaweiyi', 'xiangchang', 'liulian']
for list in lists:
     print(list)
     print("I like pepperoni pizza")
     print("I really love pizza!")

xiaweiyi
I like pepperoni pizza
I really love pizza!
xiangchang
I like pepperoni pizza
I really love pizza!
liulian
I like pepperoni pizza
I really love pizza!

4-2 动物：想出至少三种有共同特征的动物，将这些动物的名称存储在一个列表中，再使用for循环将每种动物的名称都打印出来。

　　修改这个程序，使其针对每种动物都打印一个句子，如“A dog would make a great pet”

　　在程序末尾添加一行代码，指出这些动物的共同之处，如打印诸如“Any of these animals would make a great pet!”这样的句子

lists = ['dog', 'cat', 'fox']
for list in lists:
    print(list)

dog
cat
fox

lists = ['dog', 'cat', 'fox']
for list in lists:
     print(list)
     print("A dog would make a great pet")

dog
A dog would make a great pet
cat
A dog would make a great pet
fox
A dog would make a great pet

lists = ['dog', 'cat', 'fox']
for list in lists:
     print(list)
     print("A dog would make a great pet")
     print("I really love pizza!")

dog
A dog would make a great pet
I really love pizza!
cat
A dog would make a great pet
I really love pizza!
fox
A dog would make a great pet
I really love pizza!
