You got it backwards, vim.eval() is for passing Vim values to
Python, not the other way around. You probably want vim.command()
instead:


function! Usrnm()
if has('python')
python <<EOT
import vim
import getpass
vim.command("let nm = '%s'" % getpass.getuser())
EOT
echo nm
else
echo 'no python, no cry'
endif
endfunction


For returning dictionaries, lists, or funcrefs, there is also
vim.bindeval(), thanks to ZyX. :) See the manual for details.
