I have a dataframe that looks like this:

D   X   Y   Z
A  22  16  23
A  21  16  22
A  20  17  21
B  33  50  11
B  34  53  12
B  34  55  13
C  44  34  11
C  45  33  11
C  45  33  10
D  55  35  60
D  57  34  61
E  66  36  13
E  67  38  14 
E  67  37  13

I want to get the minimum and maximum values of the categorical variable D across all the column values and so the output dataframe should look something like this:

D Xmin Xmax Ymin Ymax Zmin Zmax
A 20    22   16   17   21   23 
B 33    34   50   55   11   13    
C 44    45   33   34   10   11  
D 55    57   34   35   60   61
E 66    67   36   38   13   14

I have tried this, but no luck:

min_max_df = dfObj.groupby('D').agg({'X': [dfObj.min(axis=0), dfObj.max(axis=0)]})
