预期产量：

What would you like to do?

How much would you like to withdraw today?

$700.00 is greater than your account balance of $500.25

import sys

#account balance 
account_balance = float(500.25)


#<--------functions go here-------------------->
#printbalance function

def balance():
    print("Your current balance: $%.2f" % account_balance)

#deposit function

def deposit():
     deposit_amount = float(input("How much would you like to deposit? "))
     balance = account_balance - deposit_amount
     print("Deposit amount was $%.2f, current balance is $%.2f" % (deposit_amount, balance))

#withdraw function

def withdraw():
    withdraw_amount = float(input("How much would you like to withdraw today? "))
    if withdraw_amount > account_balance:
        print("$%.2f is greater that your account balance of $%.2f" % (withdraw_amount, account_balance))
    else:
        balance = account_balance - withdraw_amount
        print("Withdraw amount was $%.2f, your 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"):
    deposit()
elif (userchoice == "B"):
    balance()
elif (userchoice == "W"):
    withdraw()


print("Thank you for banking with us.")

enter code hereimport sys

账户余额

账户余额=浮动（500.25）

<；此处显示函数>

printbalance函数

^{pr2}$

存款函数

def deposit():
     deposit_amount = float(input("How much would you like to deposit today?\n"))
     balance = account_balance + deposit_amount
     print("Deposit was $%.2f, current balance is $%.2f" % (deposit_amount,balance))

收回功能

def withdraw():
    withdraw_amount = float(input("How much would you like to withdraw today?\n"))
    if withdraw_amount > account_balance:
    print("$%.2f is greater than your account balance of $%.2f" % (withdraw_amount, 
    account_balance))
else:
    balance = account_balance - withdraw_amount
    print("Withdrawal amount was $%.2f, current balance is $%.2f" % (withdraw_amount, balance))

这里是用户输入，使用if/else条件语句根据用户输入调用函数

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


if (userchoice == "D"):
    deposit()
elif (userchoice == "B"):
    balance()
elif (userchoice == "W"):
    withdraw()


print("Thank you for banking with us.")
