User functions don't work:

[Baldev10]

I've created a small program which runs like it should but I can't seperate the functions out and get them to work properly. Can the functions getpin(), get menuselection() be sorted out in a specific way so the program runs as normal.

This is running off a seperate class called userdetails

from Details import userdetails


def getpin():

    pin_no = ('1111', '2222', '3333')
    
    while True:

        pin_no = input("Input the no : ")

        if pin_no == '1111' or pin_no == '2222' or pin_no == '3333':
        
            
            print ("\n Hello and welcome to my program.  Please choose from one of the following options:")
        
            break
    
        else:
    
            print ("please try again ")
            
        
    
    
    Tom_Watts = userdetails ('Tom Watts \n' , '\nSidney Stringer School \n\n' 'GCSE English: Grade A \n'  'GCSE Maths:   Grade B \n' 'GCSE Physics: Grade A \n', 'GSA LTD', 'Barclays Bank', 'Good')

    Bill_Gates = userdetails ('Bill Gates \n ' '81 Oliver St \n ' 'dfdf', '6 gcses', 'CV6 7FR', 'aaa', 'good' )

    Steve_McQueen = userdetails ('Steve McQueen \n', '\nArizona High School \n\n' 'GCSE English: Grade A \n' 'GCSE Maths:   Grade A \n', 'GSA LTD', 'Lloyds Bank ', 'Average')


    dict = {
    
        '1111': Tom_Watts,
        '2222': Bill_Gates,
        '3333': Steve_McQueen, 
      
        }
    
 def getmenuselection():
    
    user =  input("\n\n 1. Userdetails \n 2. Education \n 3. Work History \n 4. Bank History \n" ' 5. Credit History \n\n  '  )

    a = '1'
    b = '2'
    c = '3'
    d = '4'
    e = '5' 

    
    if user == a:

        print (dict[pin_no].Userdetails)
    
    elif user == b:
    
        print (dict[pin_no].Education)
     
    elif user == c:
    
        print (dict[pin_no].Work_history)
    
    elif user == d:
    
        print (dict[pin_no].Bank_history)
    
    elif user == e:
    
        print (dict[pin_no].Credit_history) 


getpin()
getmenuselection()
