I have created Frame with Entry widget to ask user to input his Username and select a team, that he want to join in and also I have created an OpenMenu Widget with 4 teams that user can join.
I want to know, how to assign list to OpenMenu variations as a list. For example: Selection "Team 1" = team1Members etc.
Also I want to know, how to assign data from Entry Widget to appropriate list. For example, if user have selected "Team 1", his username will append to team1Members list.

Screenshot of this window:
There are few ways that could achieve this. The First would be to create a list of teams and unpack them using * in optionMenu then use if else condition to check which list to append to.
Here is a demo
class TeamsPage(ttk.Frame):
def __init__(self, parent, controller):
self.controller = controller
ttk.Frame.__init__(self, parent)
self.teamList = ["Team1", "Team2", "Team3", "Team 4"]
self.userEntry()
def userEntry(self):
...
self.usernameEnter = Entry(self, width=40)
self.usernameEnter.grid(row=0, column=1, padx=2, pady=10)
self.userName = StringVar(self)
self.userName.set("Team1")
teamSelection = OptionMenu(self, self.userName, *self.teamList)
teamSelection.grid(row=1, column=1, sticky=W)
confirmBtn = Button(self, text="Submit", font="Arial 16",
command= self.updateTeamList) # Command to Save username in teamXMembers list. Depends on the user selection
...
def updateTeamList(self):
if self.userName.get() == self.teamList[0]:
team1Members.append(self.usernameEnter.get())
elif self.userName.get() == self.teamList[1]:
team2Members.append(self.usernameEnter.get())
...
but a better way would be to create a dictionary. something as shown
def __init__(self, parent, controller):
self.controller = controller
ttk.Frame.__init__(self, parent)
self.teamList = {"Team1": team1Members , "Team2": team2Members,
"Team3":team3Members, "Team 4": team4Members}
self.userEntry()
def userEntry(self):
...
self.usernameEnter = Entry(self, width=40)
self.usernameEnter.grid(row=0, column=1, padx=2, pady=10)
self.userName = StringVar(self)
self.userName.set("Team1")
AdditionalText = Label(self, text="Please select a team:", font="Arial 18")
AdditionalText.grid(row=1, column=0, sticky=W, pady=15)
teamSelection = OptionMenu(self, self.userName, *self.teamList.keys())
teamSelection.grid(row=1, column=1, sticky=W)
confirmBtn = Button(self, text="Submit", font="Arial 16",
command= self.updateTeamList) # Command to Save username in teamXMembers list. Depends on the user selection
...

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

This is my first encounter with listboxes and I want to know how to insert the name of each team member into the corresponding listbox.
I have a dictionary called teams, and it's store data like that:
{'Team1': {'Aleks', Richard}, 'Team2': {'Louis'}, 'Team3': set(), 'Team4': set()}
I need to put set of names in particular listbox (ex. 'Team1' set should appear in the team1Members listbox).
I was trying to use .insert method to insert specific items from my dictionary, but I receive an error:
_tkinter.TclError: bad listbox index ".!frame.!listcheckpage": must be active, anchor, end, #x,y, or a number

It is obvious that I am doing something wrong, and I would like to know how this issue can be properly resolved.
I'm sure i'm missing something with the class/inheritence understanding.
when i hit the submit button i get this error:
I tried many variations like changing the command in the button, changing masters, defining self.controller.
how can I make the submit button to work?

here's a pic of the main window so you'll get a visual idea as well.
I think the error lies in the testPing class; in particular in these lines:
class testPing(tk.Frame):
...
clearFileRadioYes = tk.Radiobutton(self, text="yes", value=True, var=clearFile,
command=lambda: testPing.callback(clearFile.get()))
clearFileRadioYes.pack(anchor="w")
clearFileRadioNo = tk.Radiobutton(self, text="no", value=False, var=clearFile,
command=lambda: testPing.callback((clearFile.get())))
clearFileRadioNo.pack(anchor="w")
urlSubmitButton = tk.Button(self, text="Submit",
command=lambda: testPing.pingURL(urlInputBox.get(),
testPing(clearFile.get())))
You're inside testPing, so you should use self instead of using testPing explicitly. So, your code should be:
class testPing(tk.Frame):
...
clearFileRadioYes = tk.Radiobutton(self, text="yes", value=True, var=clearFile,
command=lambda: self.callback(clearFile.get()))
clearFileRadioYes.pack(anchor="w")
clearFileRadioNo = tk.Radiobutton(self, text="no", value=False, var=clearFile,
command=lambda: self.callback((clearFile.get())))
clearFileRadioNo.pack(anchor="w")
urlSubmitButton = tk.Button(self, text="Submit",
command=lambda: self.pingURL(urlInputBox.get(),
clearFile.get()))
Notice using self instead of testPing
I am aware similar questions have been answered, but I have read them thoroughly and cannot find a solution for myself.
After the BMR_method is done, and either the if, elif, or else options has completed, I want it to automatically load a new class/frame: work . But I cannot figure out how to do this. I tried adding different variations of self.show_frame(work), also tried adding parent/controller parameters to the function but it will either tell me I am missing positional arguments or that the show_frame method doesn't exist. Please help.

First, your class needs accept and save a reference to the controller so that you can access it later:
class BMR(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
...
Then, you simply need to call the controller method show_frame:
self.controller.switch_frame(work)
I have a script that creates a build in TeamCity. I am trying to create a gui that accomplishes this using Tkinder. There are multiple steps to take (ie get credentials -> input buildname -> add template - > etc), so I am using multiple frames to create the steps using the show_frame() command. My problem is the following: I make multiple REST calls, so the first step is getting the user's username and password. However, since all the pages are initialized when the program starts, all my methods that make REST calls error because they don't have the credentials yet.
How can I get the subsequent steps (and their methods) to wait for the user to input username and password?
From the code below, (in the PageOne class) I am trying to get a list of projects from BitBcuket through a REST call so I can dynamically add menu items to a menu, but I can't figure out how to wait to get the username and password.

You need to move that code out of the __init__ method (which runs when the program starts) and into the method that gets called when the frame is shown: tkraise().
