[Wien] Error in write_inwf when running init_w2w

[Gavin Abo]

It looks like the caret is pointing to the python "as" keyword.

What version of python are you using?

You can probably check with the following terminal command (of note, V 
should be uppercase): python -V

It seems that python version 2.6 or newer is needed in order to 
recognize the "as" keyword occurring to the python documentation [ 
https://docs.python.org/2.7/whatsnew/2.6.html#pep-3110-exception-handling-changes 
].

However, in the WIEN2k 14.2 usersguide [ 
http://www.wien2k.at/reg_user/textbooks/usersguide.pdf ], it seems to 
mention in section "8.2 BerryPI (Modern theory of polarization)" on page 
137 that version 2.7 of python is required.
