echo on one same line

Hi,


I would like to echo messages on same line using \r in first char but this following vim-python code echoes 19 lines out of display those 19 messages in same one line.



def VimPrint(value):
# echo printf("%s\r", string(1) ) . "foo"
vim.command( 'echo "\r" . printf("\r%s","'+str(1)+'") . "foo"' )

for i in range(1,20):
VimPrint(i)



I don't understand why it does not print all 19 messages in same display line.
Thank you for advice.
Best Regards
