python - 打印元组中的元素

Question

if select == '2':
    print('Displaying all employees\n')
    print('Employee names:\n')
    for records in record:
        print(record[0])

我的第一个选项非常好，但是我的第二个选项没有从列表中打印出“enterName”。我该如何解决？我试图找到答案，但找不到足够具体的答案。

感谢您查看并帮助我 :)。

此外，我遇到的另一个问题是，当尝试添加多个“新员工”时，它会覆盖第一个，我该如何解决这个问题？

Answer 1

有两个问题。首先是打印员工。你在做什么是打印整个数组而不是 for 循环的项目。

第二个问题是每次选择“1”时都会重新创建record。您可能应该将它放在 while 循环之前。

我还修复了标识。我希望现在好多了。

例如:

select=True
record=[]
while select:
    print ("""
Personnel Database 
    1. Add a new employee
    2. Display all employees
    3. Search for an employee
    4. View full-time employees
    5. View part-time employees
    6. View number of employee records in database
    7. Delete an employee from the database
    8. Exit
    Choose an option (1-7) or 8 to Exit
    """)
    select=input("What would you like to do? ")
    if select == "1":
        print("Add a new employee")
        enterName = input ("Enter employee name:")
        enterTitle = input ("Enter employee Job title:")
        enterRate = float (input ("Enter employee hourly rate:£"))
        enterService = float(input ("Enter number of years service:"))
        fulltime = input ("Is the employee full-time? Y/N:")
        if fulltime.capitalize == "Y":
            break
        elif fulltime == "N":
            break

        record.append((enterName, enterTitle, enterRate, enterService, fulltime))
        print ("The employee you have entered is:",record)

    if select == "2":
        print ("Displaying all employees")
        print ("Employee names:")
        for r in record:
           print(r[0])
