Construct pandas DataFrame from list of tuples of (row,col,values)

Question

I have a list of tuples like

data = [
(\'r1\', \'c1\', avg11, stdev11),
(\'r1\', \'c2\', avg12, stdev12),
(\'r2\', \'c1\', avg21, stdev21),
(\'r2\', \'c2\',          


        

Answer 1

You can pivot your DataFrame after creating:

>>> df = pd.DataFrame(data)
>>> df.pivot(index=0, columns=1, values=2)
# avg DataFrame
1      c1     c2
0               
r1  avg11  avg12
r2  avg21  avg22
>>> df.pivot(index=0, columns=1, values=3)
# stdev DataFrame
1        c1       c2
0                   
r1  stdev11  stdev12
r2  stdev21  stdev22
