2. Why?

3. Algorithm

5. Fry an egg
• Put pan on furnace
• If not vegetarian
• Put bacon in pan
• For each egg
• Break egg and put it pan
• Yield delicious egg dish

6. Assignment
b = “hello”
c=1
d=3
e=c+d

7. Three constructs
• Loops
• Choices
• Encapsulation

8. Choices

9. Python
if points < 10:
print ‘You need more points’
else:
print “You’re a winner!”

10. Ruby code
if points < 10
puts ‘You need more points’
else
puts “You’re a winner!”
end

11. Javascript code
if (points < 10) {
alert(‘You need more points’);
} else {
alert(“You’re a winner!”);
}

12. Loops

13. Python
for counter in range(5):
print ‘Counting’, counter

14. Ruby code
for i in 0..5
puts “Counting #{i}”
end

15. Javascript code
for (var i = 0; i < 10; i++) {
alert(‘Counting ‘ + i);
}

17. Encapsulation

18. Functions
def oranjeWint(team):
if ‘Huntelaar’ in team:
return True
else:
return False
…
print oranjeWint([‘Sneyder’, ‘’, ‘’])

19. Classes
class Country:
def __init__(self, name):
self.name = name
self.money = 0
def spend(self):
self.money -= 1000000
def bailout(self, amount):
self.money += amount

20. Classes
some_country = Country()
some_country.spend()
some_country.spend()
print some_country.money
some_country.bailout(1000000)

21. List
a = []
b = [1, 2, ‘hello’]
print b[0]

22. Dictionary
b = {‘winst’: 3, ‘verlies’: 0,
‘gelijkspel’: 1}
print ‘Punten bij verlies:’, b[‘verlies’]

23. Where to look?
• function reference
• modules
• classes
• API docs
