Python使用字典实现的简单记事本功能示例
本文实例讲述了Python使用字典实现的简单记事本功能。分享给大家供大家参考，具体如下：
fromtimeimportsleep,strftime
user="Cytus"
calendar={}
defwelcome():
print"Welcometousethiscalendar.%s"%user
print"Calendarisopening."
sleep(1)
printstrftime("%A%B%d%Y")
printstrftime("%H:%M:%S")
sleep(1)
print"Whatwouldyouliketodo?"
defstart_calendar():
welcome()
start=True
whilestart:
user_choice=raw_input("Atoadd,UtoUpdate,VtoView,DtoDelete,XtoExit:")
user_choice=user_choice.upper()
ifuser_choice=="V":
iflen(calendar.keys())<1:
print"Thecalendarisempty."
else:
printcalendar
elifuser_choice=="U":
date=raw_input("Whatdate?")
update=raw_input("Entertheupdate:")
calendar[date]=update
print"Updatesuccessful."
printcalendar
elifuser_choice=="A":
event=raw_input("Enterevent:")
date=raw_input("Enterdate(MM/DD/YYYY):")
if(len(date)>10)orint(date[6:])
运行结果：
>>>
Welcometousethiscalendar.Cytus
Calendarisopening.
