root = Tk()
root.geometry(' 800x500')
root.title('Boter')
root.resizable(False, False)
root.configure()

label1 = Label(root)
label1.configure(text = 'Scripts:')
label1.place(x = 0, y = 0, height = 20, widt = 300)

label2 = Label(root)
label2. configure(text = 'Your Token ')
label2.place(x = 0, y = 0, height = 20, widt = 500)

instruction = Label(root)
instruction.configure(text = 'In order to create your baht you I need my own group in VK')
instruction.place(x = 0, y = 41,height = 400, widt = 500)

body = StringVar()
token_entru = Entry(root, textvariable = body).place(x = 0, y = 21,height = 20, widt = 500)

main_slow = Text(root)
main_slow.place(x = 500, y = 21,height = 379, widt = 300)
main_com = {}
def check():
global main_slow, main_com, body
tok = str(body.get())
print(tok)

mas = main_slow.get(1.0, END).split('\n')
for i in mas:
if ':' in i:
var = i.split(':')
var[0] = var[0].strip()
var[1] = var[1].strip()
k = {f' {var[2]} : f,{var[1]}'}
main_com.update(k)
print(main_com)
botik = Bot(tok, main_com)
botik.work()
mbtn = Button(root, text = 'Start ', command = check ).place(x = 500, y = 400, widt = 300)

root.mainloop()

I insert a token, I write words in the script - I press start and here (I can’t solve with molasses)
error:
Exception in Tkinter callback

IndexError: list index out of range

Answer 1

Hello everyone and thank you so much for helping with advice,
I launched it and it works

now I will think about how to add pictures there

Answer 2

k = {f'{var[2]} : f,{var[1]}'}
Maybe instead of var[2] var[0]? Actually, the error says that the index of the dictionary is greater than the last index.
