# # 3.文件处理
# # 4.函数基础
#
# # 需要掌握的方法
# list1 = ["lee",21,"boss","zym",[1,2,3]]
#
# # insert()
# # 第一个参数：索引，第二个参数，插入内容
# # list1.insert(3,"zym")
# print(list1)
#
# # pop()
#
# # remove()
#
# # count()
# print(list1.count("zym"))
#
# # index()
# print(list1.index(21))
#
# # copy() 浅拷贝（只拷贝浅层内容,深层仍是地址转移）
# # copy为完全拷贝当前内容，内存地址和之前不一致，
# # 赋值为内存地址的指向，之前一样所以可以动态更新
# from copy import deepcopy
# list2 = list1.copy()
# list3 = list1
# list4 = deepcopy(list1)
# print(list1,"原列表")
# print(list3,"赋值")
# print(list2,"浅拷贝")
# print(list4,"深拷贝")
#
# # 对外层列表和内层列表进行拓展
# list1.append("lala")
# list1[5].append("didi")
#
# # 可以看出，深拷贝多层都为拷贝而不是地址空间的复制
# print(list1,"原列表")
# print(list3,"赋值")
# print(list2,"浅拷贝")
# print(list4,"深拷贝")
#
# # clear()
# print(list1.clear())

# # extend()
# list1_1 = [1,2,3]

# # 文件处理
# # 读写基本使用
# # 对文本进行操作
