如何将这个伪代码转换为取款机上的Python程序？

OUTPUT “Menu” 
OUTPUT “1 – Cash withdrawal” 
OUTPUT “2 – Balance” 
OUTPUT “3 – PIN Services” 
OUTPUT “4 – Pay bills” 
OUTPUT “5 – Cancel” 
OUTPUT “Please select an option 1-5:” 
user_option ← USERINPUT 

IF user_option = 1 THEN 
    proc_withdrawal() 
ELSEIF user_option = 2 THEN 
    proc_balance() 
ELSEIF user_option = 3 THEN 
    proc_pin() 
ELSEIF user_option = 2 THEN 
    proc_bills() 
ELSEIF user_option = 2 THEN 
    proc_cancel() 
ELSE 
    OUTPUT “Please only enter an option 1, 2, 3, 4 or 5” 
ENDIF

尝试是这样的注意psudeo代码和实际代码和之间的差异，因为你希望用户输入比较一个数字，你需要将字符串输入转换为INT：

import sys 

def proc_withdrawal(): 
    print("Your proc_withdrawal code goes here") 

def proc_balance(): 
    print("Your proc_balance code goes here") 

def proc_pin(): 
    print("Your proc_pin code goes here") 

def proc_bills(): 
    print("Your proc_bills code goes here") 

def proc_cancel(): 
    print("Thank you for using Simon Raivid's Cash Machine, Have a nice day!") 
    sys.exit(0) 

while True: 
    print("Simon Raivid's Cash Machine") 
    print("===========================") 
    print("\t1 – Cash withdrawal") 
    print("\t2 – Balance") 
    print("\t3 – PIN Services") 
    print("\t4 – Pay bills") 
    print("\t5 – Cancel") 
    user_option = int(input("Please select an option 1-5: ")) 

    if user_option == 1: 
    proc_withdrawal() 
    elif user_option == 2: 
    proc_balance() 
    elif user_option == 3: 
    proc_pin() 
    elif user_option == 4: 
    proc_bills() 
    elif user_option == 5: 
    proc_cancel() 
    else: 
    print("Please only enter an option 1, 2, 3, 4 or 5") 

实例应用：

    1 – Cash withdrawal 
    2 – Balance 
    3 – PIN Services 
    4 – Pay bills

Your proc_bills code goes here!
