If I understand you correctly, you are importing your module report in 
script.py. If so, you need reload.

When in IDLE, you have a python process running, in which you execute 
your program. The first time you run script.py after starting IDLE, your 
module report is imported from file. The next time you run script.py, 
there is already a module named report in memory. Then the corresponding 
file will not be executed again. Instead, the one in memory will be used.

What I do when I am developing a module for a program is that I both 
import and reload the module in my main file. Once I think I am done 
developing, I remove the reload statement. So, in your script.py, I 
would write:

import report
reload(report)
