Question

Deposit function.

Calculate the Balance - Deposit

If the action is Deposit 'D’, use a deposit function to add funds to the account

Deposit Input

userchoice = input ("What would you like to do?\n")
userchoice = 'B'
deposit_amount = 200

Deposit Output

What would you like to do?
How much would you like to deposit today?
Deposit was $200, current balance is $700.25

1. Write a function called `deposit`.
2. Request from the user the amount to be deposited. This value should be stored in a variable called `deposit_amount`. Use both the `input` and `float` methods in order to ensure the `deposit_amount` is a float value.
3. Calculate a new account balance.
4. The calculation for depositing funds into the account is `account_balance = account_balance + deposit_amount`.
5. Print the new account balance.

#import sys #no need for this module

#account balance

account_balance = float(500.25)

#<--------functions go here-------------------->

#printbalance function

def printbalance():

print("Account balance: $%.2f" % account_balance)

#deposit function

def deposit():

#accessing account_balance variable which is outside the function

global account_balance

deposit_amount=float(input('How much would you like to deposit today?'))

account_balance+=deposit_amount

print('Deposit was $%.2f, current balance is $%.2f' % (deposit_amount,account_balance))

#withdraw function

def withdraw():

#accessing account_balance variable which is outside the function

global account_balance

withdrawal_amount=float(input('How much would you like to withdraw?'))

#withdrawing only if there is enough balance

if account_balance

print('withdrawal_amount is greater that your account balance of $%.2f' % account_balance)

else:

account_balance-=withdrawal_amount

print('Withdrawal amount was $%.2f, current balance is $%.2f' % (withdrawal_amount,account_balance))

userchoice=''

#looping until user enters Q or q

while userchoice.upper()!='Q':

userchoice = input ("What would you like to do? (D/W/B or Q)\n")

#converting to upper case to reduce comparisons

userchoice=userchoice.upper()

#performing operations based on choice

if userchoice=='D':

deposit()

elif userchoice=='W':

withdraw()

elif userchoice=='B':

printbalance()

elif userchoice=='Q':

print('Thank you for banking with us.')
  
else:

print('Not a valid choice')

Answer 1

For the above program, we need to have the following things into consideration.

1. We need to subtract the amount which is withdrawn.
2. Then we need to print the output.

Following is the code for the same.

def printbalance():
    print("Account balance: $%.2f" % account_balance)
# deposit function
def deposit():
    # accessing account_balance variable which is outside the function
    global account_balance
    deposit_amount = float(input('How much would you like to deposit today?'))
    account_balance += deposit_amount
    print('Deposit was $%.2f, current balance is $%.2f' % (deposit_amount, account_balance))
# withdraw function
def withdraw():
    # accessing account_balance variable which is outside the function
    global account_balance
    withdrawal_amount = float(input('How much would you like to withdraw?'))
    # withdrawing only if there is enough balance
    if account_balance < withdrawal_amount:
        print('withdrawal_amount is greater that your account balance of $%.2f' % account_balance)
    else:
        account_balance -= withdrawal_amount
    print('Withdrawal amount was $%.2f, current balance is $%.2f' % (withdrawal_amount, account_balance))
userchoice = ''
account_balance = 0
# looping until user enters Q or q
while userchoice.upper() != 'Q':
    userchoice = input("What would you like to do? (D/W/B or Q)\n")
    # converting to upper case to reduce comparisons
    userchoice = userchoice.upper()
    # performing operations based on choice
    if userchoice == 'D':
        deposit()
    elif userchoice == 'W':
        withdraw()
    elif userchoice == 'B':
        printbalance()
    elif userchoice == 'Q':
        print('Thank you for banking with us.')
    else:
        print('Not a valid choice')

Following is the snippet of the above code.

Following is the sample output.

That was a nice question to answer
