如何在Tkinter中创建连续运行的窗口？（Python 2.7.11版）

Question

我想先弹出一个登录窗口，一旦条件满足，它就会关闭登录窗口，打开一个新窗口。你知道吗

from Tkinter import *
import tkMessageBox

#Not really sure what i'm doing here anymore

while True:

    Login = Tk()
    Login.title('Login')
    Login.geometry('400x130')

    NameLabel = Label(Login, text='Username')
    NameLabel.place(bordermode=OUTSIDE, height=25, width=100, x=100)

    NameEntryRaw = Entry(Login)
    NameEntryRaw.place(bordermode=OUTSIDE, height=25, width=100, x=200)

    CodeLabel = Label(Login, text='Code')
    CodeLabel.place(bordermode=OUTSIDE, height=25, width=100, x=100, y=30)

    CodeEntryRaw = Entry(Login)
    CodeEntryRaw.place(bordermode=OUTSIDE, height=25, width=100, x=200, y=30)

    def tbd():

        tkMessageBox.showinfo('Congrats!', 'This program is not done yet')

    def login():

        Usernames=list()
        Usernames.append('Mordecai')
        Usernames.append('Ezekiel')
        Usernames.append('Goliath')
        Usernames.append('Abraham')
        Usernames.append('Bartholomew')
        Usernames.append('Jedediah')
        Usernames.append('Solomon')
        Usernames.append('Tobias')
        Usernames.append('Yohanan')
        Usernames.append('Lucifer')

        NameEntry=NameEntryRaw.get()
        CodeEntry=CodeEntryRaw.get()

        CodeReal='116987'

        if Usernames.count(NameEntry) == 0:
            tkMessageBox.showinfo('Error!', 'Your Username is invalid! Try Again.')

        else:
            ()

        if CodeEntry != CodeReal:
            tkMessageBox.showinfo('Error!', 'The Code entered is invalid! Try Again.')

        else:
            ()     

    LoginButton = Button(Login, text="Login", command=login)
    LoginButton.place(bordermode=OUTSIDE, height=50, width=200, x=100, y=60)
    Login.mainloop()

else:

    DataBase = Tk()
    #this will be the data base
    DataBase.mainloop()

我要感谢你澄清你为我做了什么。它被证明是非常有用的！这是我已经解决的问题。我把名字放回原处，让它不用上课就可以工作，因为我发现这有点太难了。你知道吗

from Tkinter import *
import tkMessageBox 
import sys
import binascii #Not for this part

Codenames = ['Mordecai', 'Ezekiel', 'Goliath', 'Abraham', 'Bartholomew',
    'Jedediah', 'Solomon', 'Tobias', 'Yohanan', 'Lucifer']

Password = '116987' 

def close_protocol():
    if tkMessageBox.askokcancel("Quit", "Do you want to quit?"):
        sys.exit()
#Below for a later part...
def text_to_bits(text, encoding='utf-8', errors='surrogatepass'):
    bits = bin(int(binascii.hexlify(text.encode(encoding, errors)), 16))[2:]
    return bits.zfill(8 * ((len(bits) + 7) // 8))

def text_from_bits(bits, encoding='utf-8', errors='surrogatepass'):
    n = int(bits, 2)
    return int2bytes(n).decode(encoding, errors)

def int2bytes(i):
    hex_string = '%x' % i
    n = len(hex_string)
    return binascii.unhexlify(hex_string.zfill(n + (n & 1)))
#Above for a later part...
SDB = Tk()
SDB.title("SMEGJALBYT DATA BASE")
SDB.withdraw()

SDBLogin = Toplevel()
SDBLogin.title("Login")

SDBLogin.wm_protocol("WM_DELETE_WINDOW", close_protocol)

CodenameLabel = Label(SDBLogin, text="Codename")
CodenameLabel.grid(row=0, column=0)

CodenameEntry = Entry(SDBLogin)
CodenameEntry.grid(row=0, column=2)

PasswordLabel = Label(SDBLogin, text="Password")
PasswordLabel.grid(row=1, column=0)

PasswordEntry = Entry(SDBLogin, show='*')
PasswordEntry.grid(row=1, column=2)

def login_operation():
    if CodenameEntry.get() not in Codenames:
        tkMessageBox.showinfo("INVALID CODENAME!", "Please verify input in the 'Codename' field")

    elif PasswordEntry.get() != Password:
        tkMessageBox.showinfo("INVALID PASSWORD!", "Please verify input in   the 'Password' field")

    else:
        SDB.deiconify()
        SDBLogin.destroy()

LoginButton = Button(SDBLogin, text="Login", command=login_operation)
LoginButton.grid(row=2, column=1)
#Code continues...
#Code finisles....
SDB.mainloop()

它有相同的基本功能，只是按照我想要的方式组织。你知道吗
