The code you show is written for Python 3 where print() is a function, but 
you run it under Python 2 where print was a statement and the line

> print("Mashed ",veg," on the ceiling.")

tells Python to print the tuple

("Mashed ",veg," on the ceiling.")

instead of invoking the print() function. As a fix I recommend that you 
ensure that you use a Python 3 interpreter. Your other options are:

1. Remove the parens:

print "Mashed ",veg," on the ceiling." # python 2 only

2. Add

from __future__ import print_function # make print() available in py2

3 Use string formatting:

print("Mashed {} on the ceiling.".format(veg))

Parens around a single value are ignored, so here print works both as a 
statement and as a function.
