随性练习：python字典实现文本合并

主要用到，字典、字符串分割和连接、文件等操作

例如；有以下两个txt文本，要合并成一个

代码：

address_book1 = {}
address_book2 = {}
def read_address():     '''     read content from txt     :return     '''     with open("address1.txt","r") as f1:         lines1 = f1.readlines()  #返回列表         for line in lines1:             line = line.strip()  #去空白             content = line.split("，") #切割             address_book1[content[0]] = content[1]                  with open("address2.txt","r") as f2:         lines2 = f2.readlines()  #返回列表         for line in lines2:             line = line.strip()  #去空白             content = line.split("，") #切割             address_book2[content[0]] = content[1]
def merge_address(): #合并     lines  = []     header = "姓名\t     电话\t                邮箱\n"      lines.append(header)     for key in address_book1:         line = ""         if key in address_book2:             line += "\t".join([key,address_book1[key],address_book2[key]]) #拼接             line += "\n"         else:             line += "\t".join([key,address_book1[key],"********"]) #拼接             line += "\n"         lines.append(line)     for key2 in address_book2:         line = ""         if key2 not in address_book1:             line += "\t".join([key2,"************",address_book2[key2]]) #拼接             line += "\n"         lines.append(line)     with open("new_address_book.txt","w",encoding="utf-8") as f3:         f3.writelines(lines)
#         for i in lines:  #逐行写
#             f3.write(i)
if __name__ == "__main__":     read_address()
#     print(address_book1)
#     print(address_book2)     merge_address()

效果：
