You don't need curses. Some time ago somebody (I forgot the name)
posted this spinner class:
class Spinner( threading.Thread ): # a google search should find the author
DELAY = 0.1
DISPLAY = [ '|', '/', '-', '\\' ]
def __init__( self, before='', after='' ):
threading.Thread.__init__( self )
self.before = before
self.after = after
def run( self ):
write, flush = sys.stdout.write, sys.stdout.flush
self.running = 1
pos = -1
while self.running:
pos = (pos + 1) % len(self.DISPLAY)
msg = self.before + self.DISPLAY[pos] + self.after
write( msg )
flush()
write( '\x08' * len(msg) )
time.sleep( self.DELAY )
write( ' ' * len(msg) + '\x08' * len(msg) )
flush()
def stop( self ):
self.running = 0
self.join()
if __name__=="__main__":
spinner = Spinner('Be patient please ...')
spinner.start()
time.sleep(5) # doing a long operation
spinner.stop()
