I know the print statement produces the same result when
both of these two instructions are executed ,I just want to
know Is there any difference between print 3 and print '3'
in Python ?
thx everyone
Here's a future import though I used,so I can use the planned 3 with a
2x python version in the command line interpreter:

>>> import __future__
>>> x = 3
>>> y = '3'
>>> print(x)
3
>>> print(y)
3
>>>
>>> type(x)
<type 'int'>

<type 'str'>

>>> type(z)
<type 'str'>
>>>
In other words type(value), and find out the difference.
print(x) prints str(x), which is meant to be a 'friendly'
representation. To see a difference,
>>> print(repr(3))
3
>>> print(repr('3'))
'3'
