一、初识Python ----- 人人都爱列表

movies = ["The Holy Grail","The Life of Brian","The Meaning of Life"]
print(movies[1])

cast = ["Cleese","Palin","Jones","Idle"]
print(cast)
print(len(cast))

cast.append("Gilliam")   //末尾增加
cast.pop()  //删除末尾数据
cast.extend(["Gilliam","Chapman"]) //增加一个数据集合
cast.remove("Cleese") //删除特定项
cast.insert(0,"Chapman")  //在位置0之前增加一项

movies = ["The Holy Grail","The Life of Brian"]

for each in movies :
    print(each)

dir(__builtins__)  //内置方法列表
help(input)  //得到input()这个函数的功能描述

names = [‘Michael‘,‘Terry‘]
isinstance(names,list) //判断names是否属于list类型 如果是返回true

num_names = len(names)
isinstance(num_names,list) //此句返回false

movies = ["The Holy Grail",1975,"Terry jones & Terry Gilliam",97,
                       ["Graham Chapman",["Michael Palin","John Cleese",
                              "Terry Gilliam","Eric Idle","Terry Jones"]]]

def print_lol(the_list):
    for each_item in the_list:
        if isinstance(each_item,list):
            print_lol(each_item)        //递归调用
        else:
            print(each_item)

print_lol(movies)
