Transposing a dataframe without creating NaN values

[jefsummers]

Indeed, not sure what the issue is. Please post your code. I did it as:

import pandas as pd

from_csv_data = [[1,10],[2,20],[3,30],[4,40],[5,50],[6,10],[2,20],[3,30],[4,40],[5,50],[6,60]]
df = pd.DataFrame(from_csv_data)
df0 = df.set_index(0)
df0

Output:
	1
0	
1	10
2	20
3	30
4	40
5	50
6	10
2	20
3	30
4	40
5	50
6	60

df1=df0.transpose()
df1

Output:
	1	2	3	4	5	6	2	3	4	5	6
1	10	20	30	40	50	10	20	30	40	50	60
