No, certainly not. That would be terribly inefficient, since it means first

If you aren't using it get rid of it. The less distractions there are
the easier it is to debug things.

By stuck I mean, does not pass that specific line (but no errors).
How do you know that is the line it is stuck on?
def WriteOneDayToCSV(sCommonFeatures,sOtherFeatures,date):
FD=FlatData[date]
A=['UniqeDate','Year','Month','Da
I'm using Python 2.7.
By stuck I mean, does not pass that specific line (but no errors).
Like I said FD is a list of dictionaries. and sCommonFeatures are a subset
of key's that have value in all of the dictionaries.

I could resolve it by defining a small function:

for i in keys:
A=A+[mydict[i]]
return A
and then calling it: D=getValue(prog,sCommonFeatures);

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.
