Python – Convert pandas Series to DataFrame

dataframepandaspythonseries

I have a Pandas series sf:

email
email1@email.com    [1.0, 0.0, 0.0]
email2@email.com    [2.0, 0.0, 0.0]
email3@email.com    [1.0, 0.0, 0.0]
email4@email.com    [4.0, 0.0, 0.0]
email5@email.com    [1.0, 0.0, 3.0]
email6@email.com    [1.0, 5.0, 0.0]

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

index | email             | list
_____________________________________________
0     | email1@email.com  | [1.0, 0.0, 0.0]
1     | email2@email.com  | [2.0, 0.0, 0.0]
2     | email3@email.com  | [1.0, 0.0, 0.0]
3     | email4@email.com  | [4.0, 0.0, 0.0]
4     | email5@email.com  | [1.0, 0.0, 3.0]
5     | email6@email.com  | [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)

Best Answer

Rather than create 2 temporary dfs you can just pass these as params within a dict using the DataFrame constructor:

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

There are lots of ways to construct a df, see the docs
