[Solved] Making Bank account in Python 3

by


Consider saving all the details in a dictionary with the primary key as the name and pin & balance as secondary keys. Then, you can save it to a json file.

import json 
accdict ={}
accdict['Obi'] = {'Name':'Obi Ezeakachi','Pin':1111,'Balance': 5000}

Continue for all the accounts.

with open('accounts.json','w') as f:
     f.write(json.dumps(accdict))

You can now manipulate this dictionary however you want and repeat.

Also, you should call the pin checker function before making a transaction. If you’re serious about it and want it make it like an ATM, use threading to check for pin in the background while you access the details and interact with the user.
