生日检索

》题目要求

　　》》用户输入一个姓名

　　》》打印出这个姓名对应的人的生日

》程序实现

birthday = {"王江智":"1996/12/26",
            "杨顺裙":"1996/09/04",
            "王杨梅":"1990/10/15",
            "王杨灿":"1992/02/04",
            "王杨帅":"1993/10/03",
            "杨玉林":"2013/10/13"}

while True:
    name = input("Please input the name of one person whose birthday you want to know:")
    if name == "":
        break
    if name in birthday:
        print("The birthday of "+name + " is "+birthday[name])
    else:
        print("There is no birthday infomation of "+name)

》改进方案1

　　如果输入的姓名没有对应的生日，提醒用户是否要录入生日；

　　如果用户同意录入生日，那么用户下次再输入这个姓名是就会返回一个生日

　　三少想吃火锅啦，待更新......   2017年1月8日10:17:33 更新

import sys
birthdays = {
    "王杨1": "2990/10/15",
    "王杨2": "1992/02/04",
    "王杨4": "1993/10/03",
    "杨3": "2013/10/13",
    "杨5": "1993/11/05"
}
while True:
    name = input("请输入姓名(exit表示退出):")
    if "exit" == name:
        sys.exit()

    if name in birthdays:
        print("The birthday of " + name + " is " + birthdays[name])
    else:
        print("There is no information about " + name)
        choose = input("Do you want to input the information of birthday about " + name + ":")
        if ("y" == choose) or ("Y" == choose):
            date = input("Please input some information about " + name + ":")
            birthdays[name] = date
        print("The database of birthdays has upgraded.")
        print(birthdays)

》改进方案2

　　新录入的数据没能存储下来，待更新中......
