How do I make my login button follow through : tkinter

I've made this tkinkter home screen page with 3 buttons. However, when I click the buttons it comes up with error and doesn't move on to the login screen. Can anyone help?
My code:

There are few issues in your code:
show="*" should be set when creating self.userPasswordInput
command=self.togglePassword() should be command=self.togglePassword instead
self.userPasswordLabel should be self.userPasswordInput instead inside togglePassword()
inside togglePassword(), show="" is used in both if and else block. show="*" should be used in else block
Below is the required changes:
class staffLogin(tk.Frame):
def __init__(self, parent, controller, *args, **kwargs):
...
self.userPasswordInput = tk.Entry(self,width=50, font=("Helvectia",16), show="*") # set show="*" initially
...
self.showPassword = tk.Button(self, text="Show Password", command=self.togglePassword) ### self.togglePassword() -> self.togglePassword
...

for each "page" i want the frame to fill out the entire window but when i run my program, my page does not fill out the whole window. i've tried setting the weight of both the root (self) and the containers that are holding my frames but to no avail. i am unsure as of what to do next. in each page i ran the "self.configure" method in order to check whether the frame has filled out the entire window but it has not

The frames are filling your container, but your container isn't filling the window. The container is a child of self, and you use grid to add the container, but you never set the weight of the row and column for self, so it defaults to zero. That means that the container won't be allocated any extra space which results in it being centered in the window. You also don't set the sticky attribute, so even if it was allocated the space it wouldn't use it.
Personally, I recommend using pack for container since it requires fewer lines of code. However, to use grid you need to do it like this:
self.grid_rowconfigure(0, weight=1)
self.grid_columnconfigure(0, weight=1)
container.grid(row=0,column=0, sticky="nsew")

Value submitted through tkinter login page is not reflected in the database

I am designing an app in python 3 and I am using xampp as database.
I have a LogIn Page and Home Page. The idea is that when I login by entering the credentials there is navigation between the pages and the credentials are reflected in the database. Here the pages are treated as frames. I am able to navigate between the frames.
My code shows no error but the entry made in the log in page is not reflected in the database.
The code is as shown below

python tkinter creating a widget outside his frame

I want to create a widget outside his frame, but I don't know what's his master.
this is the structure.
first I created the class of the root. and then 3 classes of frames.
inside the class of the root I put a function. inside the function I created a text widget that should be located in the first one of the 3 frames
I really don't get what I should write as the master of my text widget to locate it in the first frame.
since I am a beginner if you have any advice I'd really appreciate.
thanks for attention here's the code

Tkinter change a shared variable

I am using a solution found to try and share variables throughout my code, which consists of 'Frame' classes. However, any attempt I make to try and change the value of these shared variables seems to have no effect, and after I attempt to change them, if I print it just returns blank. Any help would be appreciated.
class GolfApp(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
self.shared_data = {
"currentcourse": tk.StringVar(),
"numberofteams": tk.IntVar()}
container = tk.Frame(self)
container.pack(side="top", fill="both", expand=True)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.frames = {}
for F in (MainMenu, CreatePage, ViewPage, GetTeamsPage, ChooseCourse,
AddCourse, LoginSignUp, Login, SignUp, Highscores1, Highscores2,
Scorecards1, Scorecards2):
page_name = F.__name__
frame = F(parent=container, controller=self)
self.frames[page_name] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame("LoginSignUp")

You start by setting shared_data["current_course"] to an instance of StringVar, but then later you're resetting it to just a string.
Since it is a StringVar, you need to call the set method to set the value:
currentcourse = self.controller.shared_data["currentcourse"]
currentcourse.set(listmenu.get())
