worn venture why is it getting deleted

Maybe the bot is interpreting parts of the code as emoji spam?

Formatting code on Discord

Here's how to format Python code on Discord:

```py
print('Hello world!')
```

These are backticks, not quotes. Check this out if you can't find the backtick key.

For long code samples, you can use our pastebin.

Are you trying to upload a file? Use a code block or the pastebin instead

Hey @worn venture!

It looks like you pasted Python code without syntax highlighting.

Please use syntax highlighting to improve the legibility of your code and make it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

torn shard Are you trying to upload a file? Use a code block or the pastebin instead

sorry im a little new to inserting code on discord, but this is my entire file here

torn shard Feb 29, 2024, 1:08 AM

#

Are all the buttons showing up as cyan blue?

worn venture Feb 29, 2024, 1:10 AM

#

torn shard Are you trying to upload a file? Use a code block or the pastebin instead

no they are all showing up as whiteish, i used the cyan as a test for the background where the numbers are displayed and I could get that to change, but as far as the individual buttons they are not changing

torn shard Feb 29, 2024, 1:11 AM

#

Hmm I'm not sure, maybe get some screenshots to highlight whats wrong?

worn venture Feb 29, 2024, 1:13 AM

#

torn shard Feb 29, 2024, 1:14 AM

#

Sorry I meant of the UI

worn venture Feb 29, 2024, 1:14 AM

#

i figured it would be somewhere along line 27 where i could insert like a (bg = 'DarkOrange1') or something but im not sure

#

oh sorry

torn shard Feb 29, 2024, 1:15 AM

#

worn venture i figured it would be somewhere along line 27 where i could insert like a (bg = ...

you should be able to do bg=button_color

#

looks like that var is unused currently

worn venture Feb 29, 2024, 1:16 AM

#

ok that what I thought do you know where I would be able to declare a color for that variable?

#

or where I should put it

torn shard Feb 29, 2024, 1:17 AM

#

you already defined the text and color for each button in buttons

#

when you do for button_text, button_color in buttons then button_color is assigned each color from that list

worn venture Feb 29, 2024, 1:22 AM

#

ah I see. So should I just delete the button_color variable all together

torn shard Feb 29, 2024, 1:22 AM

#

From the loop? No you need to to use when creating each button

#

You should have something like ```py
for button_text, button_color in buttons:
btn = tk.Button(root, text=button_text, padx=20, pady=20, font=('Helvetica', 18), command=lambda b=button_text: self.on_button_click(b), bg=button_color)

#

Both the button_text and button_color variables are used to create each button

worn venture Feb 29, 2024, 1:27 AM

#

ok I got it that makes sense. I guess im just still confused on how to change the individual button colors to make it look like this

#

do I have to declare button_color to be an actual tkinter color?

torn shard Feb 29, 2024, 1:29 AM

#

It could be that your color codes are wrong? Are the gray button showing correctly?

#

I can't remember off the top of my head what strings tkinter accepts as colors

worn venture Feb 29, 2024, 1:30 AM

#

this is my output im getting

#

Im not sure if the colors are wrong because ive tried mulitple different variations like the 'cyan' and none seem to work in changing the button colors

torn shard Feb 29, 2024, 1:35 AM

#

I think this is a Mac OSX issue, try highlightbackgroundcolor= instead of bg= https://stackoverflow.com/a/42591118

Stack Overflow

How to change the foreground or background colour of a Tkinter Butt...

I've been working through the Tkinter chapters in Programming Python and encountered a problem where the foreground and background colours of a button will not change. I am working on a Mac OS X 10.6

#

actually you might have to use the tkmacosx library instead https://pypi.org/project/tkmacosx/

PyPI

tkmacosx

Tkmacosx is a Python library extension to the Tkinter module that let you change background color of the button on macOS.

worn venture Feb 29, 2024, 1:37 AM

omg youre right I cant believe i forgot to add that

torn shard Feb 29, 2024, 1:39 AM

#

Lucky google search on my part turned up someone with a similar problem

#

you are using osx right?

worn venture Feb 29, 2024, 1:40 AM

#

haha yes I am

#

perfect the colors are changing now thanks for all your help im still trying to get used to using discord for this kind of stuff

torn shard Feb 29, 2024, 1:41 AM

#

nice!

#

yeah no problem, usually though if you have a lot of code to paste just use

#

!paste

mortal sparrowBOT Feb 29, 2024, 1:42 AM

Pasting large amounts of code

If your code is too long to fit in a codeblock in Discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the Paste! button in the bottom left, or by pressing CTRL + S. After doing that, you will be navigated to the new paste's page. Copy the URL and post it here so others can see it.

torn shard Feb 29, 2024, 1:42 AM

#

If it's short enough, use a codeblock

worn venture Feb 29, 2024, 1:43 AM

#

awesome I will, thanks again
