Getting a small Python2 prog to run in Python3

[steve140]

Hi All,

I started to learn Python a few years ago, and wrote my only useful program in python2 - which I use all the time.

I want to start learning python again (py3), but when I install py3 my useful program won't run (it just flashes a window and closes).

I've forgotten everything I previously learnt, is there a 'fix quick' problem that jumps out as to why it wont run in py3 ?


It's a very simple program that monitors the clipboard for a block of text (they are links), and when it finds some it converts them into a block of links suitable for inserting into a webpage

Eg it finds on the clipboard

h+tp://anysite.com/file/textfile1
h+tp://anysite.com/file/textfile2


it converts that to
<a href=http://anysite.com/file/textfile1 target=_blank>http://anysite.com/file/textfile1</a>
<a href=http://anysite.com/file/textfile2 target=_blank>http://anysite.com/file/textfile2</a>

Then puts that new links back on the clipboard ready for pasting.


I have installed
Python2.7.13 (x86)
Pythoncard 0.8.2 (x86)
Pywin32-218
wxpython3.0 (x86)

I want to install Python3.

Thank you for any help,

Steve
