Answer 1

SoloLearn. If you can compile and run on your system, you should be able to see individual characters with delay between them.

Answer 2

@Suika King - @John's right -- except for code that runs on your device (Web and the output from PHP), input/output is "batched".
Batch processing is basically all in one unit without interaction.

Answer 3

John's got the answer :)

Answer 4

(Aside) @John: FYI, I tried fiddling with flushing in PHP too; they appear to use the same limiting system (it had no apparent effect)

Answer 5

There is a runtime limit your program is allowed.

Answer 6

Your program runs with 0.1 delay, but looks like output is buffered and only display after \n

Answer 7

thank you for your reply! so I have taken \n out and reduced the delay to .1
however there is still not delay in the output...

Answer 8

If you add more \n to output you will see more delays. The output doesn't get sent back from server until \n is seen or program exits.

Answer 9

@Kirk Schafer thanks! oh I see. so it's just python's processing mode? or is it sololearn's?

Answer 10

If not, there is:
sys.stdout.flush();
which forces the buffer to be flushed. Unfortunately, it doesn't work here as I tried it.
