python - Join on the basis of RowId - 


df1=  3    4.760291 1    4.551454 2    4.507637   df2= 1  verygood 2  3  notbad

right join 2 dataframe on basis of rowid,is possible join 2 different dataframes on basis of rowid(as don't have matching column)

expected output 3    4.760291  notbad 1    4.551454  verygood 2    4.507637

please let me know thoughts on in sql can join on basis of rowid,please guide me in achieving above logic

iiuc either join or merge should work here:

in [6]: df1.merge(df2, left_index=true, right_index=true)  out[6]:         1_x       1_y 0                     1  4.551454  verygood 2  4.507637      3  4.760291    notbad

i expect df1.join(df2) work
