pandas - sorting a dataframe by values and storing index and columns -


i have pandas dataframe matrix. looks shown below

      b   c d   1   0   5 e   0   6   2 f   2   0   3

i need values sorted , need values of index , columns of them. result should be

index column value  e       b      6  d       c      5  f       c      3

you need stack reshape nlargest:

df1 = df.stack().nlargest(3).rename_axis(['idx','col']).reset_index(name='val') print (df1)   idx col  val 0   e   b    6 1   d   c    5 2   f   c    3

for multiindex:

df2 = df.stack().nlargest(3).to_frame(name='val') print (df2)      val e b    6 d c    5 f c    3
