How can we change the data in the shelf?

Question

I opened the shelf using the following code:

#!/usr/bin/python
import shelve                   #Module:Shelve is imported to achieve persistence

Accounts = 0
Victor = {'Name':'Victor Hughes','Email':'[e-mail]','Deposit':65000,'Accno':'SA456178','Acctype':'Savings'}
Beverly = {'Name':'Beverly Dsilva','Email':'[e-mail]','Deposit':23000,'Accno':'CA432178','Acctype':'Current'}

def open_shelf(name='shelfile.shl'):
    global Accounts
    Accounts = shelve.open(name)          #Accounts = {}
    Accounts['Beverly']= Beverly    
    Accounts['Victor']= Victor


def close_shelf():
    Accounts.close()

I can add values ​​to the shelf, but I can not change the values. I defined the function Deposit (), from which I would like to change the data available on the shelf. But this gives me the following error:

Traceback (most recent call last):
  File "./functest.py", line 16, in <module>
    Deposit()
  File "/home/pavitar/Software-Development/Python/Banking/Snippets/Depositfunc.py", line 18, in Deposit
    for key in Accounts:
TypeError: 'int' object is not iterable

Here is my function:

#!/usr/bin/python

import os                       #This module is imported so as to use clear function in the while-loop
from DB import *                       #Imports the data from database DB.py

def Deposit():
        while True:
                os.system("clear")              #Clears the screen once the loop is re-invoked
                input = raw_input('\nEnter the A/c type: ')
                flag=0
                for key in Accounts:
                        if Accounts[key]['Acctype'].find(input) != -1:
                                amt = input('\nAmount of Deposit: ')
                                flag+=1
                                Accounts[key]['Deposit'] += amt

                if flag == 0:
                        print "NO such Account!"    

if __name__ == '__main__':
        open_shelf()
        Deposit()
        close_shelf()

I am new to Python. Please help. Correct me if I am wrong. I need someone to give a little clarification regarding the functioning of this code. I'm confused.

Answer 1

-, Accounts, . . :

def open_shelf(name='shelfile.shl'):
    Accounts = shelve.open(name)          #Accounts = {}
    ...
    return Accounts

def close_shelf(Accounts):
    Accounts.close()


def Deposit(Accounts):
    ...   

if __name__ == '__main__':
    Accounts = open_shelf()
    Deposit(Accounts)
    close_shelf(Accounts)

-, . Deposit() raw_input input:

input = raw_input('\nEnter the A/c type: ')

input:

amt = input('\nAmount of Deposit: ')

, input !

-, : 1) , 2) , 3) . :

for key, acct in Accounts.iteritems():  # grab a shelved item
    if val['Acctype'].find(input) != -1:
        amt = input('\nAmount of Deposit: ')
        flag+=1
        acct['Deposit'] += amt          # mutate the item
        Accounts[key] = acct            # write item back to shelf

, :

for key, val in Accounts.iteritems():
    if val['Acctype'].find(input) != -1:
        amt = input('\nAmount of Deposit: ')
        flag+=1
        val['Deposit'] += amt
        Accounts[key] = val
