[python] Pulnocni rozjimani :-)

[Petr Přikryl]

Chlapi, co jste pili? S džusem, nebo jen tak? :)

Ale nevidíte v tom žádnou záhadu, že ne? ;)

Přidám tohle...

>>> m = set()
>>> m
set()
>>> m.add('a')
>>> m
{'a'}
>>> m.add(2)
>>> m
{2, 'a'}
>>> m.add(1)
>>> m
{1, 2, 'a'}
>>> m.add(True)
>>> m
{1, 2, 'a'}
>>> m.add(1.0)
>>> m
{1, 2, 'a'}
>>> m.add(False)
>>> m
{False, 1, 2, 'a'}
>>> m.add(0)
>>> m
{False, 1, 2, 'a'}
>>> m.add(0.0)
>>> m
{False, 1, 2, 'a'}

Mějte se fajn,
   Petr
