virtualenvwrapper does not work in Windows.  You should use regular
virtualenv instead.  Read this:
http://virtualenv.readthedocs.org/en/latest/virtualenv.html#usage

Note that this blog post is HEAVILY *nix-specific, and that Windows is
a bad environment for Python development (especially Web development).
I personally recommend you just get a virtual machine running some
Linux instead of playing with Windows.

While I wouldn't say its the best environment I don't think its
fair to say Windows is "a bad environment for Python". Any
experienced Windows programmer will find it much easier to use Python on 
Windows than to learn a whole new OS and development environment.


And if they use the ActiveState version of Python (or IronPython)
they should feel quite at home.

OTOH If they already know Linux and have a choice then I'd agree
*nix is a better match. But modern Windows (post Win2k say) is not
so bad that you need a new OS. IMHO at least.

[ And for context, I run Linux on my main desktop, MacOS on my
laptop, and Windows 8.1 on a second desktop - used mainly for 
photography/video processing. And I use Python on all 3 of them)

age = input("K")


age = int(age)

Is there a shorter way to do this program???___

Yes you could do this:

print('LOL' if int(input('K')) in (1,2,3,4) else 'K')


Its shorter, but it suffers from the usual problems of
being shorter:
1) Its much harder to debug if it goes wrong
2) Almost any modifications are much harder.

Having said that there are some valid reductions you could consider:

age = int(input("K"))
if age in (1,2,3,4):  # or:  if 1 <= age <= 4:
  print ("LOL")
else:
  print ("K")
