1.用途：多個裝備、多個愛好、多門課程，甚至是多個女朋友
2.定義：內可以有多個任意型別的值，逗號分隔元素
# my_girl_friend = list(['jason','tank','sean'])
my_girl_friend = ['jason', 'tank', 'sean']
print(f"my_girl_friend: ")
my_girl_friend: ['jason', 'tank', 'sean']l = list('hello nick')
print(f"l: ")
l: ['h', 'e', 'l', 'l', 'o', ' ', 'n', 'i', 'c', 'k']1.按索引取值（正向取值+反向取值），即可存也可以取
# list之索引取值

5.有序or無序：有序
hobby_list = ['read', 'run', 'girl']
print(f'first:')
hobby_list[2] = ''
print(f'second:')
first:4522187016
second:4522187016
