message is too long

def multiply():
    global txt, skl1, a, d, m
    skl1 = txt
    txt = ""
    lbl.configure(text=txt)
    a = 0
    d = 0
    m = 1
    lbl.configure(text=skl1)

I don't see any math being done here though.

[void vapor]

look at the equal

[deft hill]

Is this function meant to multiply numbers?

[void vapor]

which one

[deft hill]

Oh, I see, m = 1 is indicating they pressed multiply.

[void vapor]

yes and if i press equalbutton then its checking
whether the variable m is 1 and then performs the action

[deft hill]

Well, the output suggests that a is also 1.

And a == 1 is checked first.

[void vapor]

yes

but on the start of the script it writen a = 0

[deft hill]

add sets it to 1 though. I'm assuming the user is pressing the number buttons before hitting multiply?

[void vapor]

but why multiply is not working when a == 0 and m == 1

[deft hill]

Because a == 1.

[void vapor]

oh i see that

[deft hill]

Did you mean for command=lambda: add(0) to be command=lambda: addbutton() or something?

[drifting knoll]

btnadd = tk.CTkButton(master=root, text="+", command=addbutton)
btnadd.grid(row=4, column=0, padx=5, pady=5)

btnadd = tk.CTkButton(master=root, text="=", command=equal)
btnadd.grid(row=4, column=2, padx=5, pady=5)
why do you have two btnadd when they are supposed to be different usages

[void vapor]

in the wrong function a = 1 is writen

[void vapor]

i dont know i fix that

[deft hill]

Your state management here is a bit of a mess. I would get rid of m, a, and d, and replace them with a single variable called something like operation. Then either make operation an Enum, or use some other set of values to indicate the operation.

Presumably, it doesn't make sense for both add and multiply to be selected at once?

[void vapor]

i forgot add and addbutton is 2 other function

oh its working now

thank you

[deft hill]

Assuming it was my help: You're welcome.

[void vapor]

yes i know that tysm
