  @kami, here’s an alternative approach. You can add a guard variable in update if you do not want to have it constantly ”running”.

  import ui class ScrollToBottomTextView(ui.View): def __init__(self, **kwargs): super().__init__(**kwargs) self.tv = ui.TextView( frame=self.bounds, flex='WH' ) self.add_subview(self.tv) self.update_interval = 1/60 def update(self): self.tv.content_offset = ( 0, self.tv.content_size[1]-self.height) if __name__ == '__main__': v = ScrollToBottomTextView() v.present() import requests text = requests.get('https://forum.omz-software.com/topic/5744/scrolling-to-the-end-of-a-textview').text lines = text.splitlines() i = 0 def add_line(): global lines, i v.tv.text += lines[i] + '\n' i += 1 ui.delay(add_line, 0.5) ui.delay(add_line, 0.5)

  @ittraining what exactly is a modern Python developer and what does he/she want and expect? Using “print” as a statement is not a bad habit but a valid proven concept dictated by an equally sound programming paradigm. I also happen to harbor the awful tradition of conceiving strings as arrays of ASCII values, a practice I do not intend to give up until a future new year resolution. These are among a slew of old fashion, deprecated (are they?) abstractions around which I built a substantial library that I do not want to “correct” according to the fancy of a few designers. In fact Python 3.xx is not an evolution of Python 2.xx but a drastic divergence. Usually, when such a paradigm shift is warranted, designers create a brand new language. Ritchie did not go with “B v2” but started “C”. So did Wirth by setting aside “Pascal” and starting “Modula”. I do want modern Python developers (whatever that means) to ride into the sunshine with their shiny Python 3.x. I just want them to live Python 2.x alone by not advocating to remove it from future releases of Pythonista. By the way, I do write codes that are compatible from Python 2.7 up to latest releases of Python 3.x when my targeted audience is varied. They are also GUI compatible across different platforms without changing any code. A few of my postings in this forum can attest to that. However, for my private routines, that work flawlessly, I want to keep them backward compatible with Python 1.x. Because sometimes I take them to my virtual computers running Windows 3.11 or Mac system 7 or OS 8 to prove to myself that I could have solved certain problems decades ago if I was not much dumber then. In my book real programmers don't eat quiche.

  Multipeer Connectivity for Pythonista. This is a Pythonista wrapper around iOS Multipeer Connectivity. Multipeer connectivity allows you to find and exchange information between 2-8 iOS and Mac devices in the same network neighborhood (same wifi or bluetooth), without going through some server.

  @ccc You're right but I did not want to improve the Python, only a way to solve the bug. Thus I added the two lines in the same style.

  Hi @JonB,
  OK I stumbled upon that post with the script also. On my second and third read and tests in the lastest Pythonista Beta (iPadOS13 and Python 3.6) I did not get it to run.

  Update:
  Now it worked with the updated version of the post and my x-callback-url inside the script ...

  pythonista3://_gears/xcallbackurl/show?action=run&x-things-id=9BD5B336-6AB0-49D9-B3F2-546B52D73375

  From there it should be solved easily

  Thank you for the information of SageMathCell.
  I think it will be a useful environment to try out my own program.
  The information that will be helpful in the future is very helpful.

  Numpy contains more C code than Python code so only @omz can upgrade Numpy in Pythonista. You might look at the Pyto app that has a newer version of Numpy.
