create a mathematis matrix with python - python

Well, I've looked a lot in the web before asking, so here's the thing.
I'm not really experienced in Python and I need to develop this Matrix Generator. Yes, it is a mathematics matrix. I'm using Tkinter and Python 3.3.
First i ask the Number of Rows and Columns and then I fill each field and the code transforms it in a notepad for other programs to read.
I used the grid method so i'm having trouble with large scale matrices. The thing is I need to apply a scrollbar. I have read that I can use frame and a friend of mine showed me a scrollbar he made using frames. Can you help me? ;D
Every time I refer to linhas is the same as rows and colunas is the same as columns.

TkInter is long in the tooth, I'd use Kivy Grid layout instead:

Checkbutton is not clickable after adding an image to it

I started working with tkinter recently and I have the following problem, I need to make the check box bigger but that is only possible with adding an image. The problem is that whenever I add an image to a button it becomes unclickable and the image is not displayed, here is my source code (part of a bigger project). My goal is to display some information and let the user decide which option he gets to keep using the check button. Any help is appreciated.

I tried some options that I saw on the forum, in another file they worked fine but when I tried to implement it in the project itself the checkbutton is still unclickable and it doesn't display the images either. tkinter checkbutton different image I tried to replicate Bryan's answer, but no luck there. Also didn't receive any console error message.
As #furas pointed in the comments above, the problem got fixed with keeping the images as member variables of the class, also the button became clickable after removing the self.toggle(var) command from checkbutton

Python Tkinter: get value from ttk.Combobox

I have the position data in the SQLite DB(employee_position). As well it's fetching the data for the position:
self.employee_position = employee_info[0][8]
However, I'm not able to insert the data. How can I insert the data into the combobox?
It does work for other fields like Entry:
#Entry
self.email_entry.insert(0, self.employee_email)
self.email_entry.config(state = 'disabled')
# Position
self.available = self.employee_position
self.position_lbl = Label(self.centerFrame, text = 'Position:', fg = '#b3b3b3', bg = '#121212')
self.position_lbl.grid(row = 7, column = 0, sticky = W, columnspan = 2, padx = 5)
self.position = ttk.Combobox(self.centerFrame, values=self.available, width = 27)
self.position.config(state = 'disabled')
self.position.grid(row = 7, column = 1, sticky = W, columnspan = 2, pady = 5)
Solution:
# Position
self.available = [self.employee_position]
self.position_lbl = Label(self.centerFrame, text = 'Position:', fg = '#b3b3b3', bg = '#121212')
self.position_lbl.grid(row = 7, column = 0, sticky = W, columnspan = 2, padx = 5)
self.position = ttk.Combobox(self.centerFrame, values=(self.available), width = 27)
self.position.set(self.employee_position)
self.position.config(state = 'disabled')
self.position.grid(row = 7, column = 1, sticky = W, columnspan = 2, pady = 5)

Tkinter: keep update a variable

I really need help, my brain is melting because of this problem. I've studied python for 2 months maybe and I'm not very expert in programming. I've got an issue... I'm using tkinter on this program; in this small GUI I'd like to always keep updated the global variable "temp", and its value should change everytime I click on the button. I know that mainloop() is a blocking method, so it is possible to do something like this?
import tkinter as tk
class App:
def __init__(self):
super().__init__()
self.screen = tk.Tk()
self.screen.geometry("400x400")
self.screen.title("Modifica temperatura ambiente")
self.screen.grid_columnconfigure(0, weight = 1)
self.label = tk.Label(self.screen, text="ENTER TEMPERATUR VALUE", fg = "black", font = ("Calibri", 10) )
self.label.grid(row = 0, column = 0, sticky = "N", pady = 10)
self.input_ = tk.Entry(self.screen)
self.input_.grid(row = 1, column = 0, sticky = "WE", pady = 5, padx = 20)
self.button = tk.Button(self.screen, text = "INVIA", command = self.getvalue)
self.button.grid(row = 2, column = 0, sticky = "WE", pady = 5, padx = 10)
def getvalue(self):
self.temp = self.input_.get()
temperatura_label = tk.Label(self.screen, text = "Last input value is " + self.temp + " degrees", fg = "red")
temperatura_label.grid(row = 3, column = 0, sticky = "S")
return self.temp
app = App()
temp = app.getvalue()
print(temp)
app.screen.mainloop()
Thank for the help!
If you want to print it in the terminal, modify your getvalue function.
Code:
import tkinter as tk
screen = tk.Tk()
screen.geometry("400x400")
screen.title("Modifica temperatura ambiente")
screen.grid_columnconfigure(0, weight = 1)
class App:
def __init__(self, master):
super().__init__()
self.master = master
self.label = tk.Label(master, text="ENTER TEMPERATUR VALUE", fg = "black", font = ("Calibri", 10) )
self.label.grid(row = 0, column = 0, sticky = "N", pady = 10)
self.input_ = tk.Entry(master)
self.input_.grid(row = 1, column = 0, sticky = "WE", pady = 5, padx = 20)
def getvalue(self):
self.temp = self.input_.get()
temperatura_label = tk.Label(self.master, text = "Last input value is " + self.temp + " degrees", fg = "red")
temperatura_label.grid(row = 3, column = 0, sticky = "S")
if self.temp == None:
print()
else:
return self.temp
app = App(screen)
def main_loop():
global app
temp = app.getvalue()
print(temp)
button = tk.Button(screen, text = "INVIA", command = main_loop)
button.grid(row = 2, column = 0, sticky = "WE", pady = 5, padx = 10)

Adding a tkcalendar DateEntry to a tkinter GUI

this my situation. I'm learning how to use python (I just started) to create a GUI with Tkinter. One requirement of my application is to be able to store "DateEntry", while investigating I came across with tkcalendar DateEntry. The problem is that DateEntry is created as a class but my already created window(GUI) is a class as well and I don't know how to combine the class DateEntry into my class client which creates a mainwindow, I think that's beyond my knowledge. I want a DateEntry to be displayed in another toplevel() window when the button "Fecha Check-in" is used. Can anyone explain how to do it?
this is the image
This is the code:

Everytime I launch the code I get a blank tkinter window.
This had a few problems.
You had an _init_ method, not an __init__ method, so the created object wasn't being initialized.
You have to send the root tkinter object to the application, with app = ImprintPlusApp(root).
You had a self.header_frame once instead of self.frame_header.
You had a columnspan = 0 (which is invalid) instead of columnspan = 1 (which doesn't really need to be specified).
I've made the above changes in the code below. It may still need debugging, as I don't know exactly what design you had in mind.
