Nella prima versione, \u00e8 stata implementata la supporto per classi con ereditariet\u00e0, gestione delle eccezioni, un sistema di moduli e i tipi fondamentali list, dict e str. L'implementazione di moduli ed eccezioni \u00e8 stata presa dal linguaggio Modula-3, mentre lo stile di codifica basato sugli spazi \u00e8 stato tratto dal linguaggio ABC, a cui Guido aveva precedentemente partecipato allo sviluppo.    <\/p>\n<p>Nel processo di creazione di Python, Guido si \u00e8 attenuto ai seguenti principi:  <\/p>\n<ul>\n<li class=\"l\"> Principi che hanno permesso di risparmiare tempo nello sviluppo:\n<ul>\n<li class=\"l\"> Prendere idee utili da altri progetti.\n<li class=\"l\"> Una ricerca della semplicit\u00e0, senza eccessiva semplificazione (il principio di Einstein: \u00abTutto deve essere spiegato il pi\u00f9 semplicemente possibile, ma non pi\u00f9 semplice\u00bb).\n<li class=\"l\"> Seguire la filosofia UNUX, secondo cui i programmi realizzano una singola funzionalit\u00e0, ma la fanno bene.\n<li class=\"l\"> Non preoccuparsi eccessivamente delle prestazioni; le ottimizzazioni possono essere aggiunte se necessario, quando si rendono necessarie.\n<li class=\"l\"> Non cercare di combattere le situazioni esistenti, ma seguire il flusso.\n<li class=\"l\"> Evitare il perfezionismo; di solito \u00e8 sufficiente un livello di \u00ababbastanza buono\u00bb.\n<li class=\"l\"> A volte \u00e8 possibile fare dei compromessi, specialmente se qualcosa pu\u00f2 essere fatto in un secondo momento.  <\/ul>\n<li class=\"l\"> Principi aggiuntivi:\n<ul>\n<li class=\"l\"> L'implementazione non deve essere vincolata a una piattaforma specifica. Alcune funzionalit\u00e0 potrebbero non essere sempre disponibili, ma la funzionalit\u00e0 di base deve funzionare ovunque.\n<li class=\"l\"> Non sovraccaricare gli utenti con dettagli che possono essere gestiti dalla macchina.\n<li class=\"l\"> Supportare e promuovere codice dell'utente indipendente dalla piattaforma, senza limitare l'accesso alle funzionalit\u00e0 e alle peculiarit\u00e0 della piattaforma.\n<li class=\"l\"> Grandi sistemi complessi devono fornire diversi livelli di estensibilit\u00e0.\n<li class=\"l\"> Gli errori non devono essere fatali e invisibili \u2014 il codice dell'utente deve poter intercettare e gestire gli errori.\n<li class=\"l\"> Gli errori nel codice dell'utente non devono influenzare la funzionalit\u00e0 della macchina virtuale e non devono portare a comportamenti indesiderati dell'interprete e a crash dei processi.  <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
