How do I Pass a List of Series to a Pandas DataFrame?

Question

I realize Dataframe takes a map of {\'series_name\':Series(data, index)}. However, it automatically sorts that map even if the map is an OrderedDict().

Is there a simpl

Answer 1

a = pd.Series(data=[1,2,3])
b = pd.Series(data=[4,5,6])
a.name = 'a'
b.name= 'b'

pd.DataFrame(zip(a,b), columns=[a.name, b.name])

or just concat dataframes

pd.concat([pd.DataFrame(a),pd.DataFrame(b)], axis=1)

In [53]: %timeit pd.DataFrame(zip(a,b), columns=[a.name, b.name])
1000 loops, best of 3: 362 us per loop

In [54]: %timeit pd.concat([pd.DataFrame(a),pd.DataFrame(b)], axis=1)
1000 loops, best of 3: 808 us per loop
