Here's my current code and the changes I've made so far from the previous version
I've reset the variables at the start because I did not want them to be reset each time the function was executed
I've added a ess_e variable for the entry of the procedure, I want this variable to store the localtime when the function is executed
I've added a ess_s variable for the exit of the procedure after all the infos are entered which should be localtime when the submit button (changed text) is pushed
The remaining problems are
root.bind does not work, I've tried several alternatives with fenetre as you suggested but I could not make it work.
I get an error when I run the 2nd function (essenceresult)
File "D:\Bureautique\Python\Scripts\interface-test.py", line 57, in essenceResult
ess_e = ent0.get()
AttributeError: 'datetime.datetime' object has no attribute 'get'
I still have to make the frame to display the previous results but I'll get there in due time :)
Thanks a lot for the help

Frame4.bind_all("<Return>", submitCommand)
submitButton.grid(row = 4, column = 0, columnspan = 2)
You also need to remove the extra Fenetre = Tk() after Frame4, as this will break it. (You can only have one Tk(), if you want more windows use Toplevel())The first problem is solved by adding Frame4.bind_all("<Return>", submitCommand). Now when you press enter it will run submitCommand, which will run essenceResult.
The second problem was using .get() on a datetime.datetime object. You can't use .get() because it isn't an entry. Instead, just have it as a parameter and don't change it. You only need .get() to get the values from a Tkinter Entry.
In this simple calculator GUI, I'm creating a frame template using classes. The frame has 2 labels, 2 entry boxes, and a button. I'd like the button to run a specific command depending on the function_call variable passed when initializing - but this doesn't work. The two_points function should be called for the first object, and one_point should be called for the second. How do I dynamically change which command is called based on which object I'm using? Thank you for taking the time to read this.

The command keyword argument of the Button constructor is supposed to be a function.
Here you give it instead a string which is the name of the method of self that should be called. So you must first get this method using setattr to be able to call it. This should do it:
def call():
method = getattr(self, self.function_call)
method()
self.calc_button = Button(
self.frame_1,
text = "Calculate",
command = call)
You then have an error in strip_string but that's another story.
I have an issues with window resizing in tkinter when a user variable is displayed. As the program takes in the name of a team and display's it later in the program, having a set size for the display window will not work as it needs to be adaptive. I have got code for centring the window, but is there a way to automatically set the size of the window?
Current Look:
team_2 = t2_entry.get()
top_2.withdraw()
confirm_screen = Toplevel(master)
w = 160 + len(team_2) + len(team_1)
h = 50
ws = confirm_screen.winfo_screenwidth()
hs = confirm_screen.winfo_screenheight()
x = (ws / 2) - (w / 2)
y = (hs / 2) - (h / 2)
confirm_screen.geometry('%dx%d+%d+%d' % (w, h, x, y))
t1_name = Label(confirm_screen, text = "Team 1: " + team_1).grid(row = 1, column = 1)
t2_name = Label(confirm_screen, text="Team 2: " + team_2).grid(row = 1, column = 2)
confirm_button = Button(confirm_screen, text = "Submit", width = 10, command = team_name_1).grid(row = 4, column = 1)
redo = Button(confirm_screen, text="Redo", width=10, command= lambda: [start_team1(), clear()]).grid(row=4, column=2)
Attempts 1:
team_2 = t2_entry.get()
top_2.withdraw()
confirm_screen = Toplevel(master)
w = 160 + len(team_2) + len(team_1)
h = 50
ws = confirm_screen.winfo_screenwidth()
hs = confirm_screen.winfo_screenheight()
x = (ws / 2) - (w / 2)
y = (hs / 2) - (h / 2)
confirm_screen.geometry('%dx%d+%d+%d' % (w, h, x, y))
t1_name = Label(confirm_screen, text = "Team 1: " + team_1).grid(row = 1, column = 1)
t2_name = Label(confirm_screen, text="Team 2: " + team_2).grid(row = 1, column = 2)
confirm_button = Button(confirm_screen, text = "Submit", width = 10, command = team_name_1).grid(row = 4, column = 1)
redo = Button(confirm_screen, text="Redo", width=10, command= lambda: [start_team1(), clear()]).grid(row=4, column=2)
Attempt 2:
team_2 = t2_entry.get()
top_2.withdraw()
confirm_screen = Toplevel(master)
w = confirm_screen.winfo_width
h = confirm_screen.winfo_height
ws = confirm_screen.winfo_screenwidth()
hs = confirm_screen.winfo_screenheight()
x = (ws / 2) - (w / 2)
y = (hs / 2) - (h / 2)
confirm_screen.geometry('%dx%d+%d+%d' % (w, h, x, y))
t1_name = Label(confirm_screen, text = "Team 1: " + team_1).grid(row = 1, column = 1)
t2_name = Label(confirm_screen, text="Team 2: " + team_2).grid(row = 1, column = 2)
confirm_button = Button(confirm_screen, text = "Submit", width = 10, command = team_name_1).grid(row = 4, column = 1)
redo = Button(confirm_screen, text="Redo", width=10, command= lambda: [start_team1(), clear()]).grid(row=4, column=2)
I think this is what you are after:
from tkinter import *
confirm_screen = Tk()
t1_name = Label(confirm_screen, text = "Team 1: " + "team_1").grid(row = 1, column = 1)
t2_name = Label(confirm_screen, text="Team 2: " + "team_2").grid(row = 1, column = 2)
confirm_button = Button(confirm_screen, text = "Submit", width = 10, command = None).grid(row = 4, column = 1)
redo = Button(confirm_screen, text="Redo", width=10, command= lambda: [start_team1(), clear()]).grid(row=4, column=2)
# You need to update the display so that the widgets are actually displayed on the screen.
# Otherwise `w` and `h` will both = 1
confirm_screen.update()
w = confirm_screen.winfo_width()
h = confirm_screen.winfo_height()
ws = confirm_screen.winfo_screenwidth()
hs = confirm_screen.winfo_screenheight()
x = (ws / 2) - (w / 2)
y = (hs / 2) - (h / 2)
confirm_screen.geometry('+%d+%d' % (x, y))
You have to first place all of the widgets and then calculate where the window should go. Also there is no need to always include the size of the window when using <tkinter.Tk>.geometry(...).
I am coding a program with Tkinter to calculate wind values. It takes Rwy Heading, Wind Direction and Wind Speed to calculate the wind whether headwind, tailwind or crosswind with the calculated relevant wind speed.
I get this error:

The IntVar is special in that it can't be directly converted to an int. To get its int value, do
rwy_var = rwy.get()
So my program compares images and deletes any that are the same, renaming the original to how many were deleted. This program works fine on my Linux (ubuntu) but when used on my Windows 8 laptop I get the error at the bottom, any advice is greatly appreciated.
