Append series to dict or list or dataframe from for loop?

问题

I have created a for loop which gives an out like this:

       SSTIME
SCODE        
0           0
1          57
3         202

I did reset_index on this series and i got this:

   SCODE  SSTIME
0      0       0
1      1      57
2      3     202

I want to append each result into a dataframe which will have column of scode and sstime.

P.S: SCODE can be of different length.

My objective is to create a Dataframe from that results.

Any help would be appreciated.

I think you need not reset_index, but concat of list of Series:

list_ser = []
#sample loop for crate Series
for x in L:
    s = create_function()
    list_ser.append(s)

df = pd.concat(list_ser)

You can convert each of these dataframes to a dictionary with pandas.DataFrame.to_dict()

And afterwards add to a list:

result = []
for x in range(1,13):
    result.append(x)
