Python: cannot print (execution flow ?)

[OneDreamCloser]

hello all,

i am interested in a small python application, which can be downloaded here : https://launchpad.net/treemap

if you run it, like this: python treemap-basic.py examle-world-population.txt

it works just fine. the problem is that even if i type a print command in the "treemap-basic.py" file : print "Hello World !" @ treemap-basic.py

i cannot see the message "Hello World !" at the Terminal.

can someone please tell me why ?

thank you

try adding it to the top of the file. sometimes the file you're editing is not the file you're trying to execute.
