[Tutor] Input parameters for functions

[Mary Knauth]

Hello Everyone,

I have a script for a school assignment, an ATM transaction script based on the purpose of creating functions.
The draft I submitted all worked fine, but the feedback from my instructor was that I needed to use parameters in my functions.
Questions:
My original py script worked 100% with no parameters in the functions, so what is the advantage of adding the parameters?
I have put in what I think should be the parameters in my new py file, all the functions work, but do you think I have utilized the parameters correctly?
def balance(account_balance)
def deposit(account_balance, deposit_amount) ———----——is ‘account_balance’ necessary?
def withdrawal(account_balance, withdrawal_amount) —— is ‘account_balance’ necessary?

Many thanks in advance for your insight and thoughts.

Warm Regards,

Mary Knauth
