Self Join in Pandas: Merge all rows with the equivalent multi-index - python-2.7

Question

I have one dataframe in the following form:
df = pd.read_csv('data/original.csv', sep = ',', names=["Date", "Gran", "Country", "Region", "Commodity", "Type", "Price"], header=0)
I'm trying to do a self join on the index Date, Gran, Country, Region producing rows in the form of
Date, Gran, Country, Region, CommodityX, TypeX, Price X, Commodity Y, Type Y, Prixe Y, Commodity Z, Type Z, Price Z
Every row should have all the different commodities and prices of a specific region.
Is there a simple way of doing this?
Any help is much appreciated!
Note: I simplified the example by ignoring a few attributes
Input Example:
Date Country Region Commodity Price
1 03/01/2014 India Vishakhapatnam Rice 25
2 03/01/2014 India Vishakhapatnam Tomato 30
3 03/01/2014 India Vishakhapatnam Oil 50
4 03/01/2014 India Delhi Wheat 10
5 03/01/2014 India Delhi Jowar 60
6 03/01/2014 India Delhi Bajra 10
Output Example:
Date Country Region Commodit1 Price1 Commodity2 Price2 Commodity3 Price3
1 03/01/2014 India Vishakhapatnam Rice 25 Tomato 30 Oil 50
2 03/01/2014 India Delhi Wheat 10 Jowar 60 Bajra 10

Answer 1

What you want to do is called a reshape (specifically, from long to wide). See this answer for more information.
Unfortunately as far as I can tell pandas doesn't have a simple way to do that. I adapted the answer in the other thread to your problem:
df['idx'] = df.groupby(['Date','Country','Region']).cumcount()
df.pivot(index= ['Date','Country','Region'], columns='idx')[['Commodity','Price']]
Does that solve your problem?
