学习笔记
1、使用判断类型函数：isinstance
2、使用函数
3、使用递归
# -*- coding: utf-8 -*-
#filename:isnstance
movies = ["the holy grail",1975,"terry jones & terry illliam",91,["graham chapman",["michael palin","jonh clees","terry cilliam","eric idile","terry jones"]]]
print(movies[4][1][3])
for each_time in movies:
print(each_time)
print('----1.Modify the output-----')
for each_item in movies:
if isinstance(each_item,list):
for neach_item in each_item:
print(neach_item)
else:
print(each_item)
print('----2.Modify the output----')
for each_item in movies:
#判断第一层是否list
if isinstance(each_item,list):
for neach_item in each_item:
#判断第二层是否list
if isinstance(neach_item,list):
for deeper_item in neach_item:
print(deeper_item)
else:
print(neach_item)
else:
print(each_item)
print('----3.Modify the output----')
#使用函数
def print_list(the_list):
for each_item in the_list:
if isinstance(each_item,list):
#可以理解为：递归
print_list(each_item)
else:
print(each_item)
print_list(movies)
