1、打开JUPYTER NOTEBOOK，新建一个空白的PY文档。
2、fruit = ["apple", "peach", "orange", "banana"]
for special_fruit in fruit:
print(special_fruit)
新建一个列表，用FOR LOOPS简单地打印出来。
3、fruit = ["apple", "peach", "orange", "banana", "pear"]
for special_fruit in fruit:
if special_fruit == "orange":
print("Eat it.")
break
print(special_fruit)
如果我们只为了找到其中某一数据，那么可以用BREAK来停止继续的操作。
4、fruit = ["apple", "peach", "orange", "banana", "pear"]
for special_fruit in fruit:
if special_fruit == "orange":
print("Eat it.")
continue
print(special_fruit)
但是有时候找到数据我们需要继续运行，那么就可以用CONTINUE。
5、fruit = ["apple", "peach", "orange", "banana", "pear"]
for special_fruit in fruit:
for index in "12345":
print(index, special_fruit)
如果要在列表关键词前加数字也是可以的。
6、fruit = ["apple", "peach", "orange", "banana", "pear"]
do_it = ["eat the ", "cook the ", "slice the ", "water the ", "take the "]
for special_fruit in fruit:
for dododo in do_it:
print(dododo, special_fruit)
同时用上两组列表，这样就可以打印出来合并的句子。
