Python lets you iterate over a list directly, so :
for d in originalData:
dateStr, freq, source = d
data[source] = freq
You could shorten that to
for dateStr, freq, source in originalData:
and if dateStr is already a string:
data[dateStr] = {source: freq}
Your code looks like you come from a c background. Python idioms are different
Agreed.
I'm not sure what you are trying to do in the second for loop, but I think you
are trying to iterate thru a dictionary
in a certain order, and you can't depend on the order
The second loop is iterating over the list dateStrs.
