Question

If the action is Balance 'B’, use a print balance function to return and print an account balance. You will need to write a function called printbalance.

a. Create a prompt for the user to input the account action. There are three possible actions:

Code	Action	Function
D	Deposit	deposit_amount
W	Withdrawal	withdrawal_amount
B	Account Balance	account_balance

Create a function to print the account_balance, print the account actions and create the action for outputting the account balance outputting.

Input Information

The following data will be used as input in the test:

userchoice = input ("What would you like to do?")
userchoice = 'B'

Output Information

Your current balance:
500.25

1. The opening balance has been assigned to a variable called account_balance equal to $500.25. Notice the use of the 'float' method in order to ensure that 'account_balance' is a float value.
2. Request the action to be taken on the account.
3. Write a print balance function that returns the account balance.
4. Create the action for selection ‘B’, Account Balance, to call the print balance function then print the account balance once the value is returned from the function.
5. Test your code.

import sys# importing the sys library

# account balance
account_balance = float(500.25)

#PPrint the balance
# This is a custom function, it returns the current balance upto 2 decimal places
def printbalance():
print("Your current balance : %2f" % account_balance)
#the function for deposit
#This is a custom function
def deposit():
deposit_amount = float(input("Enter amount to deposit : ")) # takes in input for deposit amount
balance = account_balance + deposit_amount #calculates balance
print("Deposit was $%2f, current balance is $%2f" %(deposit_am ount,balance)) # prints out the balance
#function for withdraw
#this is a custom function
def withdraw():
withdraw_amount = float(input("Enter amount to withdraw")) # takes in the withdraw amount
if(withdraw_amount > account_balance): #checks whether the amount is more than balance or not
print("$%2f is greater than account balance $%2f\n" %(withdraw_amount,account_balance)) #if yes then
print wd amount greater than balance
else:
balance = account_balance - withdraw_amount
print("$%2f was withdrawn, current balance is $%2f" % (withdraw_amount, balance))
# User Input goes here, use if/else conditional statement to call function based on user input

userchoice = input("What would you like to do?\n")

if (userchoice == 'D'):
# here deposit function is called
deposit()
elif userchoice == 'W':
# here withdraw function is called
withdraw()
elif userchoice == 'B':
# here printbalance function is called
printbalance()
else:
# it ends the program execution
sys.exit()
