• Κάθε Δευτέρα, 18:00-20:00

• 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/

Έλα εγκαίρως/νωρίς αν θες να βρεις ελεύθερη θέση :)

• Στις προηγούμενες συναντήσεις έχουμε καλύψει τις ασκήσεις 0 εως και 6

Η σελίδα της προηγούμενης συνάντησης (01) με μερικές σημειώσεις: https://www.hackerspace.gr/wiki/Learn_Python_the_Hard_Way_01

• Every Monday at 18.00-20:00

• python enthusiasts will try to learn programming "the hard way" !
  

The meetings will be in study group format, meaning that we will all learn together and there won't be a tutor. Meetings are open to everyone - just bring your laptop! They are for people that want to start learning python, so we will cover some introductory material. The only requirement is to be punctual (so if a person comes later than 18:00 please don't ask us to cover material that we have already gone through).

• Learning resource: http://learnpythonthehardway.org/book/

Come early if you want to ensure that you'll find a space to place your laptop :)

• We have previously covered exercises 0 to 6 (including 6)

The page for the previous meeting (01) with some notes: https://www.hackerspace.gr/wiki/Learn_Python_the_Hard_Way_01

This is Lesson 02 (intro session)

These events are based on peer2peer education

exercise 7

#!/usr/bin/env python2

print "Mary had a little lamb."
print "Its fleece was white as %s." % 'snow'
print "And everywhere that Mary went."
print "." * 10 # what'd that do?

maria1  = "C"
maria2  = "h"
maria3  = "e"
maria4  = "e"
maria5  = "s"
maria6  = "e"
maria7  = "B"
maria8  = "u"
maria9  = "r"
maria10 = "g"
maria11 = "e"
maria12 = "r"
maria13 = "!"
maria14 = "!"
maria15 = "!"

# watch that comma at the maria. try removing it to see what happens
print maria1 + maria2 + maria3 + maria4 + maria5 + maria6 + " " + maria7 + maria8 + maria9 + maria10 + maria11 + maria12 + maria13

print maria1 + maria2 + maria3 + maria4 + maria5 + maria6,
print maria7 + maria8 + maria9 + maria10 + maria11 + maria12 + maria13 + maria14 + maria15

print maria1 + maria2 + maria3 + maria4 + maria5 + maria6, \
maria7 + maria8 + maria9 + maria10 + maria11 + maria12 + maria13 + maria14 \

exercise 8

print formatter % (1, 2, 3, 4)
print formatter % ("one", "two", "three", "four")
print formatter % (True, False, False, True)
print formatter % (formatter, formatter, formatter, formatter)
print formatter % (
    "I had this thing.",
    "That you could type up right.",
    "But it didn't sing.",
    "So I said goodnight."
)

print formatter2 % (1, 2, 3, 4)
print formatter2 % ("one", "two", "three","four")
print formatter2 % (True, False, False, True)
print formatter2 % (formatter2, formatter2, formatter2, formatter2)
print formatter2 % (
    "I had this thing.",
    "That you could type up right.",
    "But it didn't sing.",
    "So I said goodnight."
