convert an array into a list of objects

All,

I have a dataframe which I am using to extract all unique identifiers as follows:

myTradeFrame['coll_cusip'].unique()

the output is:

array(['BRSUJX0F8', 'BRSU17NB8', '010831BE4', ..., '912828J84',
       '912828R36', '912810RC4'], dtype=object)

How can I convert that array into something that looks like this:

('BRSUJX0F8', 'BRSU17NB8', '010831BE4', ..., '912828J84',
           '912828R36', '912810RC4')

Many Thanks

Since myTradeFrame['coll_cusip'].unique() returns a numpy array, use tuple method.

array = myTradeFrame['coll_cusip'].unique()
list = tuple(array)

To get it to return something in the form you asked for (which isn't a list but a tuple), you should use tuple:

tuple(myTradeFrame['coll_cusip'].unique())

you can just do this myTradeFrame['coll_cusip'].unique().tolist()
