Create Empty Dataframe in Pandas specifying column types

Question

I\'m trying to create an empty data frame with an index and specify the column types. The way I am doing it is the following:

df = pd.DataFrame(index=[\'pbp\         


        

Answer 1

Just a remark.

You can get around the Type Error using np.dtype:

pd.DataFrame(index = ['pbp'], columns = ['a','b'], dtype = np.dtype([('str','float')]))

but you get instead:

NotImplementedError: compound dtypes are not implementedin the DataFrame constructor
