Not able to define logic in else for pattern printing

Got stuck expected pattern printing

Below is my code , I have printed the first part but got stuck with else part printing required some input how to build logic for else part

n=29
breaking= int((n+1)/2)
lst  = [ len(str(num).zfill(2)) * ' ' for num in reversed(range(1,n+1)) ]
cnt=-1
for row in range(1,n+1):

  if row <= breaking:
    lst[cnt]=str(row).zfill(2) + '   '
    print(' '.join(lst))
    cnt = cnt - 1 
    
  else:  

Expected output :

                                          01   
                                       02    01
