PROBLEM DESCRIPTION:

Online shopping cart is a virtual shopping trolley, where shoppers can put all of
their want-to-buy products in, review to make adjustments in quantity, product
attributes, etc., and remove it before or during the checkout if they change their
mind.

FEATURES OF OUR SHOPPING CART:

• We used database SQLite which helps in maintaining the records easily and properly as
well.
• It has permanent storage of the users.
• Our shopping cart displays the products.
• It can export from cart.
• You can delete the items that you don’t want from cart.
• You can delete the history.
• It displays the entire history as well along with the time.

FILES IMPORTED

import functions
from datetime import datetime
import sys
import time
from abc import ABC, abstractmethod

CLASS LOGIN

Class login asked us to enter the name, mail, password and then check from the database
whether the credentials are correct or not. If they are not correct, it gives a appropriate
message and if correct then it gives us the options to go to products, export from cart, delete
from cart, delete from history, display history. You can choose any and the program will run
accordingly.

class login:
 def check_id(self):
 global username
 self.name=input("ENTER USERNAME: ")
 self.email=input("ENTER EMAIL: ")
 self.password=input("ENTER PASSWORD: ")
 try:
 flag=0
 for i in self.all_data:
 print(i)
 if (i[1]==self.email) and (i[0]==self.name) and (i[2]==self.passw
ord):
 print(flag)
 flag=1
username=self.name
 if flag==1:
 #go to product or cart:

 try:
 print("what do you want to?")
 print("1.go to product")
 print("2.export from cart ")
 print("3.delete from cart ")
 print("4.delete from history")
 print("5.display history")
 self.want=input("ENTER NUMBER: ")
 if self.want=="1":
 p=all_product()
 elif self.want=="2":
 c=add_to_cart()
 c.export()
 elif self.want=="3":
 r=remove_from_cart()
 r.delete_from_cart()
 elif self.want=="4":
 h=shopping_history()
 h.delete_from_history()
7
 elif self.want=="5":
 h=shopping_history()
 h.display_history()
 else:
 raise ValueError
 except ValueError:
 print("ENTER CORRECT CHOICE")


 else:
 raise ValueError
 except ValueError:
 print("DATA ENTERED WAS INVALID ")
 print("Do you want enter data again or sign up for new account :")
 self.choice=input("FOR ENTERING DATA AGAIN PRESS 1 FOR SIGN PRESS 2 :
")
 if self.choice=="1":
 self.check_id()
 elif self.choice=="2":
 s=sign_up()
 else:
 pass
 def __init__(self):
 self.all_data=self.all=functions.show_all("user.db","user_info")
 self.check_id()

CLASS SIGNUP:

The signup class allows to open an account. It asks some questions and create an account. Your
username, password and an email are required to make an account. After entering the essential
data all the data will go into the database.

class sign_up:
 def pass_aunc(self):
 if self.password == self.pass_check :
 now = datetime.now()
 current_time = now.strftime("%H:%M:%S")
 functions.add_one_data("user.db","user_info",(self.name,self.emai
l,self.password,current_time))
 try:
8
 print("what do you want to?")
 print("1.go to product")
 print("2.EXIT")
 self.want=input("ENTER NUMBER: ")
 if self.want=="1":
 p=all_product()
 elif self.want=="2":
 sys.exit()
 else:
 raise ValueError
 except ValueError:
 print("ENTER CORRECT CHOICE")
 else:
 s=sign_up()
 def __init__(self):
 self.name=input("ENTER USERNAME: ")
 self.email=input("ENTER EMAIL: ")
 self.password=input("ENTER PASSWORD: ")
 self.pass_check=input("ENTER PASSWORD AGAIN:")
 self.pass_aunc()`
