Pandas pivot_table rearangging rows to columns

Question

I am a Pandas newbie and I like it a lot. I am trying to create a pivot table and having trouble. This is a small image file explaining my problem:

I have tried the following line but it doesn't output the way I want.

df = df.pivot_table(index = 'Time', columns = 'Item', values = 'Value', aggfunc = list)

Answer 1

try this:

output = pd.pivot_table(df, values='Value', index=['Time', 'ID'],
 columns=['Item'], aggfunc=np.sum, fill_value="")
