calculate mean, n, min, max and stdev in once on a specified column

Question

Hi could you tell me how to co the same in one line of code. Is it possible to compute all stats bellow in once?

mean = dftemp.groupby('Q1_1')['EI'].mean()
count = dftemp.groupby('Q1_1')['EI'].count()
stdev = dftemp.groupby('Q1_1')['EI'].std()
EImin = dftemp.groupby('Q1_1')['EI'].min()
EImax = dftemp.groupby('Q1_1')['EI'].max()
