Ciao a tutti,
mi sto lanciando nella creazione di piccole GUI per i programmi che finora ho lanciato da riga di comando, ma non sta andando molto bene.
Guardando in giro ho deciso di cominciare con PAGE e ho creato una prima GUI di prova che dovrebbe solamente lanciare uno script alla pressione di un bottone, solo che lancia lo script in apertura e poi premendo il bottone non fa nulla
Qualcuno saprebbe dirmi dov'è l'errore (di seguito allego il codice)? Grazie

Python: 
#! /usr/bin/env python
#  -*- coding: utf-8 -*-

--- i due messaggi sono stati uniti ---
ok, ho risolto: nel primo file dove ho scritto self.Button1.configure(command=prova_GUI_support.esegui_pca()) dovevo omettere le parentesi.
Qualcuno sa spiegarmi il perché però? Grazie
 
Ultima modifica:
Non conosco Python ma suppongo che la presenza delle parentesi veniva interpretata come esecuzione in fase di configurazione e non a ogni pressione.
