So I have typed the code out exactly as it is within the lesson, but there is no text window like there should be. I tested the code outside of Replit just to make sure it wasn’t a bug, but it didn’t work there either. It seems like there is something missing.

Can you please share the code? I may or may not be up to day 66

import tkinter as tk

window = tk.Tk()
window.title(“Groovey Bot”) # Sets the name of the window in the border
window.geometry(“300x300”) # Sets the size of the window in pixels

label = 0

def updateLabel():
global label
label += 1
hello[‘text’] = label

hello = tk.Label(text = label) # Creates a text box
hello.pack() # ‘pack’ places the element on the screen

button = tk.Button(text = “Don’t Click me!”, command = updateLabel) # Creates a button
button.pack()

text = tk.Text(window, height=1, width=50)
text.pack

tk.mainloop()

There should be nothing being printed. There are no print statements so its working as intended. @DavidAtReplit can say if this is intentional.

6

It’s supposed to put a text box that you can type into in the main window.

The next step in the lesson is using information that is typed into that text box.

7

I’ll grab my original solution repl and take a look

Is this not the code we put in the solution? https://replit.com/@DavidAtReplit/Day-66-Solution-1#main.py

And just to clarify the text box in this is just a label, it’s not meant to be typed into - the buttons are supposed to do the work

Yes, I figured it out. the text.pack was missing the () at the end. I watched the video again and noticed that it was in the video, but not in the tutorial window.

And the issue was before I got to the project, it was on the 2nd slide “Adding Text”

My Output is buffering forever and not showing anything :anguished:
Does anybody know what the problem might be?

13

Replit as a whole (more specifically web hosted repls) is having issues right now.

Hi @surfineer and @Firepup650 thanks for your messages. Are you still experiencing problems? If so can you link to your Repl here please?

Hi @IanAtReplit , it’s very flaky.
This week was working fine, but today I’m on the final tkinter project and it’s not running anymore (Output is loading and loading but nothing happens) :slightly_frowning_face:

Here’s the link to my repl (unfinished!):
main.py - Day 69: Visual Novel - Replit

16

I do see the first two screens and buttons work on the first screen

17

I switched to PyCharm and finished my code there and it works :relieved:
SO I’m gonna close the tkinter chapter now! Woohoo
:partying_face:

Thank you for posting that! I had the same issue and couldnt figure out what I did wrong lol. It looks like it was missing for lots of the text.

I got stuck for a while in two places on this lesson:

In the tutorial, the first two code demonstrations in the “Adding Text” section and the first one in “Placing Items” have a text.pack missing the brackets. (Thanks MrKrinle for posting about it)

I also tried to pass variables through my button commands, but this caused the command to run when the program started and do nothing when the button was pressed. I figured out a fix from this.

this is not working even after copy pasting everything in the lesson. The code is not adding the numbers I put in. Please help @DavidAtReplit

import tkinter as tk
window = tk.Tk()
window.title("Hello World") 
window.geometry("300x300") 

label = 0

def updateLabel():
  global label
  number = text.get("1.0","end") # Gets the number from the text box (starting at the first position and going to the end.) and stores in the number variable
  number = int(number) #Casts to an integer. I've done this on a separate line to prevent the line above getting too complex, but you can combine the two.
  label += number # Adds the number from the text box to the one in the label.
  hello["text"] = label
  

hello = tk.Label(text = label) 
hello.pack() 

button = tk.Button(text = "Click me!", command = updateLabel) 
button.pack()

text = tk.Text(window ,height=1, width = 50)
text.pack()

tk.mainloop()

Try this fix of your code, it’s not feature-complete but will work

import tkinter as tk

def updateLabel():
    number = text.get("1.0", "end-1c") # Get the number from the text box (excluding the newline character)
    try:
        number = int(number) # Convert the number to an integer
        global label
        label += number # Add the number from the text box to the existing label
        hello.config(text=label) # Update the label text
    except ValueError:
        pass

window = tk.Tk()
window.title("Hello World")
window.geometry("300x300")

label = 0

hello = tk.Label(window, text=label)
hello.pack()

button = tk.Button(window, text="Click me!", command=updateLabel)
button.pack()

text = tk.Text(window, height=1, width=50)
text.pack()

tk.mainloop()
