I have data in the following form in a csv file.
**Item Dept Sale_Qty Sale_Date Start_Date End_Date Sale_Fcst**
Item1 Dep1 237 3/30/2012 4/17/2012 4/17/2014 0
Item1 Dep1 211 4/6/2012 4/17/2012 4/17/2014 0
Item1 Dep1 155 4/13/2012 4/17/2012 4/17/2014 0

Item1 Dep1 125 5/11/2012 4/17/2012 4/17/2014 0
What I want to retain is the following.
**Item Dept Sale_Qty Sale_Date Start_Date End_Date Sale_Fcst**
Item1 Dep1 237 3/30/2012 4/17/2012 4/17/2014 0
Item1 Dep1 211 4/6/2012 4/17/2012 4/17/2014 0
Item1 Dep1 155 4/13/2012 4/17/2012 4/17/2014 125.5525055
Item1 Dep1 145 4/20/2012 4/17/2012 4/17/2014 107.5810699
Item1 Dep1 179 4/27/2012 4/17/2012 4/17/2014 89.33208466
Item1 Dep1 120 5/4/2012 4/17/2012 4/17/2014 71.19781494
Item1 Dep1 125 5/11/2012 4/17/2012 4/17/2014 53.19638062
So that the Sale_Date values do not repeat and the information in the columns Sale_Qty and Sale_Fcst get combined into the same row. Is there a way using excel command or say, Python/pandas to achieve the same?
I have spent days trying to do it using excel but failed. Trying manually is driving me crazy since the records run into thousands of rows! I am even trying to learn Python to achieve the same but failure stares at me there as well!
Any help would be much appreciated.
Thanks!
