ATM Machine and Management System With Python

So Guys we are making an ATM Management System using python. In this project you need to know be familiar with file handling and json files (Java Script Object Notation). We will be using json file to store data using dictionaries.

Working of Program

We will make a conditions for

1)Deposit of amount

2) Withdraw of amount.

3)Check balance

4)Adding an account using pin number only in which we will generate the pin randomly by using random module in range of (1000, 99999) to ensure the pin is secured with 4 to 5 digits.(This condition is not included in it).

5)Exit (To come out of the program)

code in data.json (You will have to add demo data to ensure your program is working)

{

“1111”: { “name”: “samuel”, “age”: 27, “amt”: “52000” },

“1112”: { “name”: “sam”, “age”: 27, “amt”: “304542” },

“1113”: { “name”: “jane”, “age”: 27, “amt”: 50000 },

“1114”: { “name”: “mimi”, “age”: 27, “amt”: 50000 },

“1115”: { “name”: “james”, “age”: 27, “amt”: 50000 },

“1116”: { “name”: “jake”, “age”: 27, “amt”: 50000 }

}

import json

while True:

print(“\t\t\twelcome To The SBI”)

with open(‘data.json’,’r+’) as f:

d=json.load(f)

if pin in d:

print(f”welcome {d[pin][‘name’]}”)

print(“1)Check Balance\n2)Withdraw\n3)deposite\n4)Exit”)

choice=input(“Enter your Choice”)

if choice == ‘1’:

print(f”The Remaining amount in Your Account is:- {d[pin][‘amt’]}”)

print(“Thank You”)

elif choice == ‘2’:

width = int(input(“enter the amount you want to widthdraw”))

if width >= int(d[pin][‘amt’]):

print(“insufficient balance”)

print(“Thank You”)

else:

remain=int(d[pin][‘amt’])- width

d[pin][‘amt’] = str(remain)

print(f”widthdrawl successful\nRemaining Amount is:- {d[pin][‘amt’]}”)

print(“Thank You”)

with open(‘data.json’,’w’) as k:

json.dump(d,k)

elif choice == ‘3’:

depo = int(input(“enter the amount you want to deposite”))

drem=depo + int(d[pin][‘amt’])

d[pin][‘amt’] = str(drem)

print(f”Deposite successful\nUpdated Amount is:- {d[pin][‘amt’]}”)

print(“Thank You”)

with open(‘data.json’,’w’) as k:

json.dump(d,k)

elif choice == ‘4’:

exit()

else:

print(“Wrong Input Given Please Choose Correct Option”)

:- Working

:-Now for first condition (check balance)

Showed amount is coming from the file data.json

Now for second condition (withdraw of amount)

1. when you give amount more than it had

2. when you give amount less than it had

:-Now to deposit Amount

:- And If you want to exit out of the program

The program has come out of the file path

Note:-(Adding of account through pin) will be added soon Thank You
