Question

这是我编写的程序，但我无法创建使用def等def withdrawl ( current_amount, withdrawl_amount )函数的银行程序。并使用if，elif和else作为选项列表。请帮忙。

balance = 2000
rt = 0.01
years = 0

while True:
 print('===============================')
 print(' Welcome to STEVENS UNIVERSAL BANK ')

 print('Please Choose an Option')
 print('Option 1: Withdrawl')
 print('Option 2: Deposit')
 print('Option 3: Check_Balance')
 print('Option 4: Balance with Updated Interest')
 print('Option 5: Exit')
 print('===============================')

 option = int(input('Choose an Option:'))
 years = years + 1

 if option == 1:
  withdrawl = int(input('How much do you want to Withdrawl?:'))
  balance = balance - withdrawl
  print (' New Balance :', balance)
 elif option == 2:
  deposit = int(input('How much do you want to Deposit?:'))
  balance = balance + deposit
  print (' New Balance:', balance)
 elif option == 3:
  print('Balance:', balance)
 elif option == 4:
  balance = balance * ( 1 + ( 0.0001 * years ))
  print (' Updated Balance', balance)
 elif option == 5:
  print (' Thank you for using THE STEVENS UNIVERSAL BANK ')
  exit()
 else:
  print('Invalid Input')

已使用elif和else。看起来你在数学上也理解如何处理退出。

Python 3文档解释了如何声明和调用函数的语法在4.6. Defining Functions部分。

def fib(n):    # write Fibonacci series up to n
    """Print a Fibonacci series up to n."""
    a, b = 0, 1
    while a < n:
        print(a, end=' ')
        a, b = b, a+b
    print()

# Now call the function we just defined:
fib(2000)

如何使用def函数创建银行程序，返回以及是否有其他人？
