Can ternary work with return and print in python?

Question

Ternary is easy to use when checking for none-y variables.

>>> x = None
>>> y = 2 if x else 3
>>> y
3

If i want to check for none-ity before i return is there a ternary equivalence to:

def foobar(x):
  if x:
    return x*x
  else:
    print 'x is None-y'

Is there something that looks like:

def foobar(x):
  return x*x if x else print 'x is None-y'

Answer 1

Use print as a function, import it from __future__ in Python2:

>>> from __future__ import print_function
>>> def foobar(x):
      return x*x if x else print ('x is None-y')
... 
>>> foobar(0)
x is None-y
>>> foobar(2)

Another alternative will be to use sys.stdout:

>>> import sys
>>> def foobar(x):
      return x*x if x else sys.stdout.write('x is None-y\n')
... 
>>> foobar(0)
x is None-y
>>> foobar(2)
