Answer

try via T attribute,rename_axis(),reset_index() and melt() method:

out=(df.T
     .rename_axis(index=['Group','Weeks'])
     .reset_index()
     .melt(['Group','Weeks'],var_name='Days',value_name='Amount'))

OR

via T attribute,rename_axis(),stack(),reset_index() and rename() method:

out=(df.T
   .rename_axis(index=['Group','Weeks'])
   .stack()
   .reset_index()
   .rename(columns={'level_2':'Days',0:'Amount'}))
