list
# [1,2,3,4,miaoge,9.8]
# list_01 = list('nihao')
# print(list_01)
# 列表推导式
# (发生变化后标签 标签 for in iterbale)
# i;i*2 for i in
# i可迭代对象里面的元素
筛选条件
# list_01 = [i*2 for i in range(1,10) if i%2==0]
# for i in list_01:
# # print(i)
# print(list_01)
# s1 = 'ni,hao'
# re = s1.capitalize()
capitalize首写字母变换
# re = s1.swapcase()
swapcase字母大写
# print(re)
# l1 = [1,2,3,4,5]
# l1.append('python')
# print(l1)
# re = list([1,2,3,4,5])
# print(re)
# insert :插入
