如何在熊猫中将2个列表的列表转换为2列df

Question

I have this list (which is created using append function twice):

['2017-04-03.csv', 108.0, '2017-04-04.csv', -12.0]

(it's much longer and length can very) and when using results = pd.DataFrame({'col':results}) I get the following:

              col
0  2017-04-03.csv
1             108
2  2017-04-04.csv
3             -12

I am looking to get:

                  col
2017-04-03.csv   108
2017-04-04.csv   -12

I checked the solutions offered here , here and here but they all not work as I expect/need. thanks

Answer 1

Slicing is your friend -

pd.DataFrame(results[1::2], index=results[::2], columns=['col'])

                  col
2017-04-03.csv  108.0
2017-04-04.csv  -12.0

Even indexed elements form the index, and odd indexed elements form the column values.
