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

Build the list of series:

import pandas as pd
import numpy as np

> series = [pd.Series(np.random.rand(3), name=c) for c in list('abcdefg')]

First method pd.DataFrame.from_items:

> pd.DataFrame.from_items([(s.name, s) for s in series])
          a         b         c         d         e         f         g
0  0.071094  0.077545  0.299540  0.377555  0.751840  0.879995  0.933399
1  0.538251  0.066780  0.415607  0.796059  0.718893  0.679950  0.502138
2  0.096001  0.680868  0.883778  0.210488  0.642578  0.023881  0.250317

Second method pd.concat:

> pd.concat(series, axis=1)
          a         b         c         d         e         f         g
0  0.071094  0.077545  0.299540  0.377555  0.751840  0.879995  0.933399
1  0.538251  0.066780  0.415607  0.796059  0.718893  0.679950  0.502138
2  0.096001  0.680868  0.883778  0.210488  0.642578  0.023881  0.250317
