Stdout is buffered, meaning it will wait for a newline, or for some large
amount of output, before actually outputting the characters to the screen. Use
the flush method to force it to be output now. Writing to sys.stdout directly
also lets you avoid the space that a print-comma gives you:
for i in range(10):
sys.stdout.write(".")
sys.stdout.flush()
time.sleep(1)
sys.stdout.write("\n")
