What about classes?Can't I use a class where I would use a struct in C?

You are right, there's no switch statement in Python.
For example, you could use dictionaries as it is shown in "Learning Python":

 >>> choice = 'ham'
 >>> print {'spam': 1.25,                      # a dictionary-based 'switch'
  ...            'ham' : 1.99,                      # use has_key() test 
for default case
  ...            'eggs' : 0.99,
  ...            'bacon' : 1.10} [choice]
1.99

I hope someone can explain that.I've just realised that I don't understand 
this example at all. It looks nice, though.

For a Newbie like me the alternative solution with an if statement is 
better to understand:

 >>>if choice == 'spam' :
...       print 1.25
...   elif choice == 'ham' :
...       print 1.99
...   elif choice == 'eggs':
...      print 0.99
...   elif choice == 'bacon' :
...      print 1.10
...   else:
...      print 'Bad choice'
...
1.99

Well, I guess one should prefer the dictionary-based version.Seems to be 
more flexible.

Hope this helps .
