Define a primitive data type: Difference between revisions

=={{header|Python}}==

This doesn't really apply as Python names don't have a type, but something can be done:

<lang python>>>> class num(int):

def __init__(self, b):

if 1 <= b <= 10:

return int.__init__(self+0)

else:

raise ValueError,"Value %s should be >=0 and <= 10" % b

>>> x = num(3)

>>> x = num(11)

Traceback (most recent call last):

File "<pyshell#394>", line 1, in <module>

x = num(11)

File "<pyshell#392>", line 6, in __init__

raise ValueError,"Value %s should be >=0 and <= 10" % b

ValueError: Value 11 should be >=0 and <= 10

>>> x

3

>>> type(x)

<class '__main__.num'>

>>> </lang>
