class DataUserPassword():
def __init__(self, user,password):
self.user = user
self.pasword = password
if len(user) < 3:
print("Your username is less than 3 characters! ")
elif user.isnumeric():
print("Username must have at least one letter! ")
elif user.isalpha():
print("Username must have at least one number! ")
if len(password) < 10:
print("Your Password is less than 6 characters! ")
elif user in Data.keys():
print
else: Data.update({user:password}) ,print(Data)



class DataBook():
def __init__(self,Book,NameBook,Date,Sdate):
self.book = Book
self.Nbook = NameBook
self.Day = Date
self.Endate = Sdate
if Book == "enter" :
EnBook.update({NameBook:p1.user}) , print(f"Your UserName And The name of the delivered book : -> {EnBook}")
if Date == "enter":
EnDate.update({Sdate:NameBook}) , print(f"Book delivery date: -> {EnDate}")




while True:
p1 = DataUserPassword(user = input("Enter The UserName: "),password = input("Enter The Password: "))
p2 = DataBook( Book = input("Enter The Enter: "),NameBook = input("Enter The Neme of Book: "),Date = input("Enter The Enter: "),Sdate= input("Enter the book delivery time: "),)
with open('convert.txt', 'w') as convert_file:
convert_file.write(json.dumps(Data))
with open('convert.txt', 'w') as convert_file:
convert_file.write(json.dumps(EnBook))
