How to clear previous console output?

[Mike Rovner]

(For console output) Use \r.

Example:

for i in range(100):
   print '%s\r' % ' '*20, # clean up row
   print '%d%%' % i, # note ending with comma
print

Note that it works only in real console window, not in simulated one (like
in WinIDE).
That is cross-platform.
