创建一个名为“帐户”的对象，用于银行业务

Question

1. 创建一个名为Account的对象。这将用于银行system.
2. Initialize帐户，该帐户有三个数据作为输入: Firstname、Lastname和初始deposit.
3. Create 4附加成员函数:存款、取款、费用计算，如果帐户中的总金额小于1000美元，则费用计算为每月10美元。利息设定为3%。

我已经让代码工作了一次，但是所有变量都是整数，这意味着它们中没有一个是小数。这就是我现在所拥有的，我一直在犯错误：

input = 'John Doe 4893.27'

account = str(input)
account = account.split()

first_name = account[0]
last_name = account[1]
i_deposit = account[2]

i_deposit = float(i_deposit)
i_deposit = '{:.2f}'.format(i_deposit)

new_amount = 0
fee = 0
d = 0
w = 0


def Deposit(d):
    d = float(d)
    d = '{:.2f}'.format(d)
    d = bin(d)
    new_amount = bin(i_deposit) + d
    new_amount =  bin(new_amount)
    return bin(new_amount)


def Withdraw(w):
    w = float(w)
    w = '{:.2f}'.format(d)
    w = bin(w)
    new_amount = bin(i_deposit) + w
    new_amount = bin(new_amount)
    return bin(new_amount)


def FeeCalc(money):
    money = float(i_deposit)
    if money <= 1000:
        fee = 10
    else:
        fee = 0
    fee = '{:.2f}'.format(fee)
    return fee

i = 0
def Interest(i):
    i = float(i_deposit)
    i = int(i)
    i = i * .03
    i = '{:.2f}'.format(i)
    return i

dep_amount = Deposit(d)
wit_amount = Withdraw(w)
net_amount =  sum(dep_amount, wit_amount)
new_amount = int(new_amount)
int_fee = Interest(i)

Withdraw(276.84)

print(first_name, last_name, 'account information:', '\nInitial deposit: $', i_deposit, '\nNew balance: $', new_amount, '\nFee: $', fee, '\nInterest: $', int_fee)

最近我似乎无法修复的错误是：

Traceback (most recent call last):
  File "/Users/shardae/PycharmProjects/HW1/main.py", line 55, in <module>
    dep_amount = Deposit(d)
  File "/Users/shardae/PycharmProjects/HW1/main.py", line 23, in Deposit
    d = bin(d)
TypeError: 'str' object cannot be interpreted as an integer

当您使用“{：.2F}‘.format(Some_variable)”函数时，实际上是将指定值的任何变量转换为字符串。我不相信那是你想要的。在此之后，让我对您的程序进行一些修改，以保持代码的精神。

input = 'John Doe 4893.27'

account = str(input)
account = account.split()

first_name = account[0]
last_name = account[1]
i_deposit = float(account[2])

def Deposit(amount, d):
    amount = amount + d
    return amount

def Withdraw(amount, w):
    w = (int(w) * 100) / 100    # Example of insuring precision to two decimal places
    amount = amount - w
    return amount

def FeeCalc(money):
    fee = 0
    if money <= 1000.00:
        fee = 10
    return fee

def Interest():
    i = float(i_deposit)
    i = int(i)
    i = i * .03
    return i

new_amount = i_deposit              # Set the work field to the initial deposit balance

int_fee = Interest()                # Calculate interest and add it to the balance

new_amount += int_fee               

new_amount = Withdraw(new_amount, 276.84)   # Calculate the new balance once the withdrawal amount is applied

fee = FeeCalc(new_amount)               # Subtract any bank fee if the balance has dropped below $1000.00

new_amount -= fee

print(first_name, last_name, 'account information:', '\nInitial deposit: $', '{:.2f}'.format(i_deposit), '\nNew balance: $', '{:.2f}'.format(new_amount), '\nFee: $', fee, '\nInterest: $', int_fee)

代码仍然使用浮点变量。但是，只有在打印输出中才会发生两个小数点的特定格式设置。

继续回顾这些调整，看看这是否满足了你的解决方案的精神。

希望这能有所帮助。

致以问候。
