[Tkinter] Login Help

[wxnerd]

I need help figuring out my code as it is not running after this part (Line 49), where it shows, "Welcome..." any thoughts??

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

t=0 #Authentication Page from tkinter import * import tkinter.messagebox as tm class LoginFrame(Frame):     def __init__(self, master):         super().__init__(master)         print("Welcome to the Weather Engine. Please enter your seven digit Forecaster ID Number followed by your password.")         self.label_username = Label(self, text="Forecaster ID")         self.label_password = Label(self, text="Password")           self.entry_username = Entry(self)         self.entry_password = Entry(self, show="X")           self.label_username.grid(row=0, sticky=E)         self.label_password.grid(row=1, sticky=E)         self.entry_username.grid(row=0, column=1)         self.entry_password.grid(row=1, column=1)           self.checkbox = Checkbutton(self, text="Remember Me")         self.checkbox.grid(columnspan=2)           self.logbtn = Button(self, text="Login", command=self._login_btn_clicked)         self.logbtn.grid(columnspan=2)           self.pack()     def _login_btn_clicked(self):         # print("Clicked")         username = self.entry_username.get()         password = self.entry_password.get()           # print(username, password)         if username == "12141" and password == "7777":             tm.showinfo("Login info", "Welcome Admin")             forecaster="Admin"             t=1                       if username == "25101" and password == "12345":             tm.showinfo("Login info", "Welcome User1")             t=2         root = Tk() lf = LoginFrame(root)   root.mainloop() if t != str(0):      print("Hello " + forecaster + ", What do you want to do?")

Output:
"Welcome Forecaster" 

Thank you in advance

root.mainloop() runs an infinite loop until all GUI windows are closed,
it won't move onto the line

1	if t != str(0):

until you close all GUI windows.
Also, your code shown has no line 49
