I do this so much that on my main development machines, I have a line
in my vimrc file

  nnoremap <leader>p oimport pdb; pdb.set_trace()<esc>
  nnoremap <leader>P Oimport pdb; pdb.set_trace()<esc>

which maps the the leader key (defaults to "\") followed by p/P to
insert the pdb line below/above the current line.  Saves bunches of
time & hassle.  I'm sure it's equally easy in other quality editors.
