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)
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
