Without the following statement, print does not work the "new" way.  What 
you are printing is a tuple of the two list elements.

from __future__ import print_function

test = [
    ["VG", "Virgin Islands, British"],
    ["VI", "Virgin Islands, U.S."],
    ["WF", "Wallis and Futuna"],
    ["EH", "Western Sahara"],
    ["YE", "Yemen"],
    ["ZM", "Zambia"],
    ["ZW", "Zimbabwe"]]

for z in test:
  if z[0].startswith('Z'):
     print(z[0],z[1])
print()

----results----
ZM Zambia
ZW Zimbabwe

Comment out "from __future__ import print_function" and you'll get:
