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

You can use the following:

df = pd.DataFrame({'a': pd.Series([], dtype='int'),
                   'b': pd.Series([], dtype='str'),
                   'c': pd.Series([], dtype='float')})

then if you call df you have

>>> df 
Empty DataFrame 
Columns: [a, b, c]
Index: []

and if you check its types

>>> df.dtypes
a      int32
b     object
c    float64
dtype: object
