Combining rows in pandas [duplicate]

Answer 1

Something in the same line. Sorry not the exact replica.

mydata = [{'subid' : 'B14-111', 'age': 75, 'fdg':1.78},
          {'subid' : 'B14-112', 'age': 22, 'fdg':1.56},{'subid' : 'B14-112', 'age': 40, 'fdg':2.00},]
df = pandas.DataFrame(mydata)

gg = df.groupby("subid",sort=True).sum()
