The reason for your error is because of this:

root.mainloop()
enregistrer_nom_utilisateur()

mainloop() runs until the window is closed. When the window is closed, all the widgets (frames, entries) are deleted. When you call enregistrer_nom_utilisateur(), there is not a frame.entry1 object anymore. When you try to delete the text in frame.entry1 this causes an error.

You can look here to see a tkinter version of hangman.

thank you but I get this error message after inverting mainloop() and enregistrer_nom_utilisateur() places:

That is because your game logic is wrong. enregistrer_nom_utilisateur() should not call itself. It should be called when you press Entrer. Did you check out that link in my previous post. Your code is a mess. It shows that you do not understand how to organize a tkinter application. That link will help you understand how tkinter works, understand the event driven nature of GUI programming which is very different from script programming.
