• Κάθε Δευτέρα, 18:30-20:30

• Συναντήσεις για εκμάθηση προγραμματισμού σε python.
  

Θα είναι υπό την μορφή study group, δηλαδή όλοι θα μαθαίνουμε παρέα και δεν θα υπάρχει κάποιος "δάσκαλος". Οι συναντήσεις είναι ανοιχτές σε όλες και όλους - αρκεί να φέρεις το laptop σου! Απευθύνονται σε ανθρώπους που θέλουν να ξεκινήσουν με python κι άρα θα είναι αρκετά εισαγωγικές. Η μοναδική δέσμευση είναι να τηρηθεί αυστηρά το ωράριο (δηλαδή εάν κάποιος ή κάποια αργήσει, να μην μας ζητήσει να γυρίσουμε πίσω για να καλύψουμε κάτι που έχουμε ήδη πει).

• Θα ακολουθήσουμε την παρακάτω ύλη: http://learnpythonthehardway.org/book/

• Στις προηγούμενες συναντήσεις έχουμε καλύψει μέχρι και την:
