Hi Konstantin,
This happens because our console is not a real one, it's just emulating
a Python console inside a graphical interface. That's why things like
"\b" and "\r" don't work. For more information please see our Issue 195
<http://code.google.com/p/spyderlib/issues/detail?id=195>.
But I think the IPython guys have solved this problem, so if you have
the chance please update to Spyder 2.2 and IPython 0.13.2.
Cheers,
Carlos

Hello all,
I am trying to dynamically write to the same line of the console. The
code below does work in standard consoles but dosn't work in Spyder,
at least with its default settings. Why?
I am working under Windows, Spyder 2.1.11.
import sys
import time
sys.stdout.write('static and ')
last_lenght = 0
for i in "\\|/-\\|/-":
sys.stdout.write('\b' * last_lenght) # go back
sys.stdout.write(' ' * last_lenght) # clear last dynamic output
sys.stdout.write('\b' * last_lenght) # reposition
outText = i + 'dynamic'
sys.stdout.write(outText)
last_lenght = len(outText)
sys.stdout.flush()
time.sleep(0.5)
