python question

Hi, ALL,
I hope it is OK to ask a question about Python itself.

Here is my problem.

I have following code:

def MyFunc(self, originalData):
     data = {}
     dateStrs = []
     for i in xrange(0, len(originalData)):
           dateStr, freq, source = originalData[i]
           data[str(dateStr)] = {source: freq}
           dateStrs.append(dateStr)
    for i in xrange(0, len(dateStrs) - 1):
          currDateStr = str(dateStrs[i])
          nextDateStrs = str(dateStrs[i + 1])

It seems very strange that I need the dateStrs list just for the
purpose of looping thru the dictionary keys.
Can I get rid of the "dateStrs" variable?

Thank you.

As this is such a basic question I suggest you take it to either the tutorial mailing list or the main one. These are available as gmane.comp.python.tutor or gmane.comp.python.general, but can be accessed via other mechanisms.

My fellow Pythonistas, ask not what our language can do for you, ask what you can do for our language.
