print "." problem, when I print something using "for" or "while" statement

[choies1]

Sometime Jupyter notebook MicroPython Kernel prints "." that I didn’t print, when I use ‘print()’ with "for" or "while" statement,

Followings are my codes. When I use a serial terminal(ex. Teraterm), the output is OK. However, there is a print dot(.) problem when I use Jupyter notebook.

How can I solve the problem? I use Windows 10 (64bit) and Python3 (installed by Anaconda) and ESP32 board with MicroPython.

==========  My codes &Results   =========
[Using Teraterm]

MicroPython v1.9.4-684-g51482ba92 on 2018-11-21; ESP32 module with ESP32
Type "help()" for more information.

-------code -----------------------------
import time
for k in range(10):
     print("k = {0}".format(k))
     time.sleep(1)

------ results ------------------
k = 0
k = 1
k = 2
k = 3
k = 4
k = 5
k = 6
k = 7
k = 8
k = 9

--- same code using Jupyter notebook MicroPython Kernel ---
import time
for k in range(10):
     print("k = {0}".format(k))
     time.sleep(1)
------ results ------------------
k = 0
k = 1
k = 2
k = 3
k = 4
.k = 5
k = 6
k = 7
k = 8
k = 9
---------------------------------

As you see the above result. dot(".") is printed (".k = 5"), even though I didn't print dot(".").

The IPython kernel prints dots ('.') every few seconds when nothing seems to be happening (like during the time.sleep() function) to show that it's still alive and not crashed. It's a debug feature, like a mouse-cursor timer.

Maybe I should remove it, and just rely on the "Kernel Idle/Active" filled circle on the title bar to the right of the "Micropython - USB"

I was thinking if I should put this in as a setting to the %serialconnect command -- probably to default as off, but so that I could have it when things are getting a bit flakey at times.

Thank your replay. As you said, <Maybe I should remove it, and just rely on the "Kernel Idle/Active" filled circle on the title bar to the right of the "Micropython - USB"> is good to me. Could you make it an option?
