[Tutor] Program gets stuck after a creating a list from dictinary items!

[Ali Torkamani]

Thanks, I checked,  FD is not empty,
Thanks for reminding about the flush and close, but I think some thing is
wrong with:
D=[prog[key1] for key1 in sCommonFeatures]

In the debug mode it works fine from the command line, but in the for loop
it gets stuck.
