So I just started using Google Colab and I keep getting this error:
TclError: cannot use geometry manager grid inside . which already has slaves managed by pack
I'm trying to make a GUI window that takes in the information from the user and saves it.
Everything I've read online says that the issue is that I'm using pack() and grid(), but I'm only using grid(). The error starts when I first try to place my labels (sourceLabel).
I'm so confused, any help would be great.

This is a very weird error you had here, I just re-wrote your code using the canvas and pack method, instead of a grid, rows, and columns. Just make sure you are using Python3x Just so none of these weird bugs resurface, hope this helps, you can play around with the x and y values at the bottom, and you can mess with the height and width values at the top when we set the canvas. Happy coding!

The problem:
I am trying to update the same text widget box from a function that contains some text. Instead a whole new text window appears every time.
Here is my code:
from tkinter import *
import os
#Tkinter graphics
homepage = Tk()
homepage.title("My first GUI")
# set size of window
homepage.geometry('1200x400')
# Add image file
bg = PhotoImage(file = "maxresdefault.png")
# Show image using label
label1 = Label( homepage, image = bg)
label1.place(x = 0, y = 0)
label2 = Label( homepage, text = "Test App")
label2.pack()
# Create Frame
frame1 = Frame(homepage)
frame1.pack()
#button initatiors
def buttonupdate():
S = Scrollbar(homepage)
T = Text(homepage, height=100, width=30)
T.pack()
T.pack(side=RIGHT, fill= Y)
S.pack(side = RIGHT, fill = Y)
S.config(command=T.yview)
T.insert(END, "test")
T.config(yscrollcommand=S.set, state=DISABLED)
# Static buttons
tickets30button = Button(text = "This is button 1", command=buttonupdate)
tickets30button.place(x=0, y=26)
mcibutton = Button(text = "This is button 2")
mcibutton.place(x=0, y=52)
hdebutton = Button(text = "This is button 3")
hdebutton.place(x=0, y=78)
homepage.mainloop()
Here is the result if I click on the first button three times:
Let me know if you have any suggestions that I can try.
Thank you for your time,
I was able to update my text window instead of create a new one, upon each click of a button, thanks to #TheLizzard.
He mentioned to move the section of code that creates the text window outside of the function and keep the section of code that creates the text, inside the function.
Before:
#button initiators
def buttonupdate():
S = Scrollbar(homepage)
T = Text(homepage, height=100, width=30)
T.pack()
T.pack(side=RIGHT, fill= Y)
S.pack(side = RIGHT, fill = Y)
S.config(command=T.yview)
T.insert(END, "test")
T.config(yscrollcommand=S.set, state=DISABLED)
After: (UPDATED)
S = Scrollbar(homepage)
T = Text(homepage, height=100, width=30)
T.pack(side=RIGHT, fill= Y)
S.pack(side = RIGHT, fill = Y)
S.config(command=T.yview)
T.config(yscrollcommand=S.set, state=DISABLED)

You need to pass in the tkinter root
cb = tk.Checkbutton(root, text=name, padx=0, pady=0, bd=0, variable=var)
Similar to your other buttons
self.search_button = tk.Button(root, text='Search', command=self.search)
When you delete the contents of the text widget, that causes the checkbuttons to be deleted as well.
This is from the official tcl/tk documentation on the text widget [1]:
The embedded window's position on the screen will be updated as the text is modified or scrolled, and it will be mapped and unmapped as it moves into and out of the visible area of the text widget. Each embedded window occupies one unit's worth of index space in the text widget, and it may be referred to either by the name of its embedded window or by its position in the widget's index space. If the range of text containing the embedded window is deleted then the window is destroyed. Similarly if the text widget as a whole is deleted, then the window is destroyed.
I have been trying to resolve the error:
ImportError: No module named tkinter
however no solutions from previous questions seem to be working at all.
I have tried :
sudo apt-get install python3-tk
and tkinter installed successfully, yet the issue remains.
I've tried making the t in tkinter uppercase as i'm using Python 3.8.2 yet that did not work.
I have also tried reinstalling/repairing Python as tkinter supposedly comes with the latest Python versions.
Attempting to open my file with python3 main.py results in the following error
Traceback (most recent call last):

Any ideas?
So for a project on my school I am trying to make an GUI where I can add some info for some email so it will send it automatically through an python script.
Now I do have a small problem. I made some entry-points but for some reason I can not add text to the left of the entr-ypoints. Does anyone know how to do that?
I am trying to get 'sending to:', 'name:', and 'course:' to the left of the corresponding entry-points.
It might sounds silly, but please do not change to much of the actual code. It has to be like this for the project.
Kind regards,
Allard

You should not be trying to place widgets at exact coordinates. Tkinter has managers for handling layout in a logical manner: pack and grid. These take care of problems with different window sizes, different resolutions, and different fonts, and are superior to placing elements at specific x/y coordinates.
Since you want to create a grid of label/entry pairs, grid is the correct choice.
entry1=tk.Entry(root)
entry2=tk.Entry(root)
entry3=tk.Entry(root)
label1 = tk.Label(root, text="Sending to:")
label2 = tk.Label(root, text="Name:")
label3 = tk.Label(root, text="Course:")
label1.grid(row=0, column=0)
entry1.grid(row=0, column=1)
label2.grid(row=1, column=0)
entry2.grid(row=1, column=1)
label3.grid(row=2 column=0)
entry3.grid(row=2, column=1)
You need to save the item ID of each canvas1.create_window(...) and then use the item ID to find the position of the entry and put a text before the entry using canvas1.create_text(...):
...
# function to put a prompt before the 'entry' item
def create_prompt(prompt, entry):
# get the bounding box of the Entry item
bbox = canvas1.bbox(entry)
# create a canvas text item and put it before the Entry item like below:
# (x-5,y) (x,y)
# -------+ +-----------------+
# prompt: | Entry |
# +-----------------+
#
# note that bbox[0] is the x-coordinate of the top-left of entry item
# bbox[1] is the y-coordinate of the top-left of entry item
# using anchor='ne' means that the (x, y) of the text is the top-right corner of the text
# and finally return the item ID of the canvas text item
return canvas1.create_text(bbox[0]-5, bbox[1], text=prompt, anchor='ne')
entry1=tk.Entry(root)
entry1_item = canvas1.create_window(200, 60, window=entry1)
create_prompt('sending to:', entry1_item)
entry2=tk.Entry(root)
entry2_item = canvas1.create_window(200, 80, window=entry2)
create_prompt('name:', entry2_item)
entry3=tk.Entry(root)
entry3_item = canvas1.create_window(200, 100, window=entry3)
create_prompt('course:', entry3_item)

A 'refresh' button that would clear the Label of its content and lets you overwrite it.
I am taking your function ImageVerification() as a blackbox and assuming it is working.
The reason this is happening is because you create a new Label, whenever the Submit button is pressed. What you have to do is to create the display Label outside the function and configure its text, whenever the button is pressed. Something like this.
l1 = Label(root, text="", width=200)
l1.pack(side='bottom', padx=50, pady=50)
def display():
ImageVerification(pathlist[0], pathlist[1])
l1.configure(text=Scriptoutput)
#Scriptoutput is the output variable from the main code.
submit_button = Button(text="Submit", width=15,command = display)
submit_button.pack(side='bottom', padx=15, pady=15)
