I have a table and I like create partitioning and like to keep only last 10 days of data.The idea is to drop the partitioning using a  script (data which is older than 10 days ).Every day the table gets around half a million of rows except saturday and sunday . The table have the timestamp column.
How can I do the partitioning of this table so that it can be manageable using partitioning and I can manage and keep only 10 days of data. Please note that the data is not required older than 7 days but I will keep for another day or 2 ( so may be 10 days at the max).

What version of Oracle?

If you are on 11gR2 take a look interval partitioning.

There are restrictions so I suggest you look in the docs to see if this is an option for you:
Restrictions on Interval Partitioning

The above link says the interval partition only works on date or number column  but I have timestamp so this is not for me.

I'm not sure what you are reading that states a timestamp won't work but it will.

Check out the example in the AskTom link and you will see that it is based on a timestamp.
