Yu probably want to keep the filename unouched and 
use a variable like country here.

You are trying to use file in the rename but you have 
modified the filename so it is no longer valid. I'd use 
filename as the variable in the for loop and country 
for the modified version used to access the dictionary.

Where does the Uganda come from? Loooks like the 
real code has an extra print statement somewhere?
