{} around my string in Python using tkinter

Question

I use Tkinter, and I wanted to print a more sophisticated text on a button. It consists of strings parts, variables that contain e.a 'MyString', and integer Variables. What it does when i grid the buttons, is following :

enter image description here

Here is the code for my first button :

bouttons_annuler[(mon_compteur_annulations_loc)].config(text = ("Vend", action_corr_numero_ventes_loc, "x", vente_suivie_loc,"a", entry_prix_loc, euros.get(), "\n","Annuler"))

and for my second button :

bouttons_annuler[(mon_compteur_annulations_loc)].config(text = ("Offre achat", action_corr_numero_achats_loc, "x", achat_suivie_loc, "Annuler"))

Where action_corr_numero_ventes_loc represents 'Facebook' ; vente_suivie_loc represents 20 (as an integer) ; entry_prix_loc represents also 20 (as an integer) ; euros.get() represents euros=StringVar(master=root) euros.set('€ :')

Why does this happen, and how can i solve this? i tried to apply the str() function to all of it, but it didn't work (wouldn't really have made sense if it worked)

where do I use it? I tried using it around everything, but it gives me an error saying that format() takes at most 2 arguments. — jean michel

You get the curly braces because you are giving tkinter a tuple. The curly braces are the internal tcl interpreter's method of rendering lists.

You should explicitly convert your data to a string to get rid of the curly braces. For example:

bouttons_annuler[...].config(text = ' '.join(("Vend", action_corr_numero_ventes_loc, ...)))

Of course, you don't have to use join. You can format the data however you want. If you give tkinter a tuple or list, though, you're at the mercy of it deciding how to represent your data.

Did you actually mean reading or rending itself, over at "...method of rending lists" .

@CoolCloud: I meant "rendering". Thanks for pointing that out.

Try This:

Edit:

texts = 'Vend {} x {} a {} {} \n Annuler'.format(action_corr_numero_ventes_loc, vente_suivie_loc, entry_prix_loc, euro)

bouttons_annuler[(mon_compteur_annulations_loc)].config(text =texts)

It still gives me {€ :}

and gives me this error : bouttons_annuler[(mon_compteur_annulations_loc)].config(text = ('Vend %s x %d a %d %s' % action_corr_numero_ventes_loc, vente_suivie_loc, entry_prix_loc, euros.get())) TypeError: not enough arguments for format string

I changed texts into :

texts = 'Vend {} x {} a {} {} \n Annuler'.format(action_corr_numero_ventes_loc, vente_suivie_loc, entry_prix_loc, euros.get())

(just added the s.get() after euro and the \n) and it worked! Thank you so much !
