Convert pandas Series to DataFrame

Question

I have a Pandas series sf:

email

[email protected]    [1.0, 0.0, 0.0]

[email protected]    [2.0, 0.0, 0.0]

[email protected]    [1.0, 0.0, 0.0]

[email protected]    [4.0, 0.0, 0.0]

[email protected]    [1.0, 0.0, 3.0]

[email protected]    [1.0, 5.0, 0.0]

And I would like to transform it to the following DataFrame:

index | email             | list

_____________________________________________

0     | [email protected]  | [1.0, 0.0, 0.0]

1     | [email protected]  | [2.0, 0.0, 0.0]

2     | [email protected]  | [1.0, 0.0, 0.0]

3     | [email protected]  | [4.0, 0.0, 0.0]

4     | [email protected]  | [1.0, 0.0, 3.0]

5     | [email protected]  | [1.0, 5.0, 0.0]

I found a way to do it, but I doubt it's the more efficient one:

df1 = pd.DataFrame(data=sf.index, columns=['email'])

df2 = pd.DataFrame(data=sf.values, columns=['list'])

df = pd.merge(df1, df2, left_index=True, right_index=True)

Answer 1

Instead of creating two temporary dfs, just pass these as params within a dict using the DataFrame constructor:

pd.DataFrame({'email':sf.index, 'list':sf.values})
