• 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 10

Η σελίδα της προηγούμενης συνάντησης (#02) με μερικές σημειώσεις:

• 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 10 (including 10)

This is Lesson 03 (intro session)

These events are based on peer2peer education

Exercise 11

print "How old are you ?",
age = raw_input()
print "How tall are you ?",
height = raw_input()
print "How much do you weigh?",
weight = raw_input()
# weight = int ( raw_input() )
# weight_number = int ( weight ) 

print "So, you 're %r old, %r tall and %r heavy." % ( age, height, weight ) 
print "So, you 're %s old, %s tall and %s heavy." % ( age, height, weight ) 

# print "So, you 're %f old, %f tall and %f heavy." % ( float(age), float(height), float(weight) ) 
# print "So, you 're %d old, %d tall and %d heavy." % ( int(age), int(height), int(weight) ) 

print "How old are you ?",
age = input()
print "How tall are you ?",
height = input()
print "How much do you weigh?",
weight = input()
# weight = int ( raw_input() )
# weight_number = int ( weight ) 

print "So, you 're %r old, %r tall and %r heavy." % ( age , height, weight ) 

print "So, you 're %s old, %s tall and %s heavy." % ( age, height, weight ) 

Exercise 12

a = raw_input ("How old r u ? ")
h = raw_input ("How tall r u ? ")
w = raw_input ("How much do u weight? ")

print "So, u r %r old, %r tall & %r heavy." % ( a , h, w )


python2 -m pydoc raw_input

Exercise 13

#!/usr/bin/env python2

# import sys

# sys.argv
from sys import argv

# variables/arguments are initialized from argv
script, first, second, third = argv 

# print script argument
print "The script is called:" , script 
# print first argument
print "Your first variable is: " , first
# print second argument
print "Your second variable is: ", second
# print third argument
print "You third variable is: ", third

print "Number of arguments is: ", len( argv )
print 

# print script argument
print "The script is called:" , argv[0]
name = raw_input ("Your name hesse ? ")
# print first argument
print "Your first variable is: " , argv[1]
# print second argument
print "Your second variable is: ", argv[2]
# print third argument
print "You third variable is: ", argv[3]
# print your name
print "Thank you:  %r , %r %r %r " % ( name , argv[2] , argv [3] , argv [1 ] )
