Re: Is it time to develope using Python 3K?
We'll see if/when that starts happening. If Python 2 is what companies use in production, their developers will build also new packages to prioritize python 2.

Re: Is it time to develope using Python 3K?
Further thought - it's still unclear which one is the dead end, python 2 or python 3. There is very little motivation still to prioritize python 3 when python 2 has all the users and developers - everyone ensures their stuff works on python 2, and python 3 is "voluntary extra".

PIP is routinely used with python 2 - in fact a lot of modules in PyPI is Python 2 only. You can get it here: https://pip.pypa.io/en/latest/installing.html On Fri, Jan 16, 2015 at 1:20 PM, Edward K.

Re: Is it time to develope using Python 3K?
This thread has inspired me to get things working in Python3, i.e. Leo plus all the plugins I use. I have PyQt5 installed in Python3, so this includes fixing Qt4/5 stuff. Notes so far: paramiko is a package for Ubuntu 14.04 for 2.7 but not 3, no big deal, pip3 can install it. I've been loading the deceased plugin 'qtframecommands' from the .pyc file for who knows how long. :-) The livecode plugin uses https://pypi.python.org/pypi/meta, but this happens leo-editor:0> sudo pip3 install meta Downloading/unpacking meta Downloading meta-0.4.1.tar.gz (45kB): 45kB downloaded Running setup.py (path:/tmp/pip_build_root/meta/setup.py) egg_info for package meta Installing collected packages: meta Running setup.py install for meta Installing depyc script to /usr/local/bin File "/usr/local/lib/python3.4/dist-packages/meta/bytecodetools/print_code.py", line 12 print instr ^ SyntaxError: invalid syntax odd that pip thinks it's available for py3. I think Leo's livecode plugin would be much better without the meta dependency, it's being used for ast object to source code conversion, maybe livecode could adequately guess at the code from the input code. I.e. given input of "d[2][3:7] = 6*7" meta handles the recreation of the d[2][3:7] part on the output side, I think. Anyway inevitably there will be packages not available for python3, not a surprise. Cheers -Terry -- You received this message because you are subscribed to the Google Groups "leo-editor" group.

Here are some further thoughts: Guido himself clearly believed (and probably still believes) that Python 2 is *not* good enough. Otoh, Guido's remarks in recent PyCon keynote speeches indicate that he will never again attempt such a radical break with existing code. He seems somewhat unhappy with the transition to Python 3. That may be an understatement. Or not. He has reasons to put a brave face on things. Kent's remark that more and more packages are being ported to Python 3 is more important than I originally acknowledged. The available packages, not the problems of big shops, are what most people care about, or should care about. In some ways, the big shops don't matter all that much. They can "take care of themselves" and they can always stick with Python 2.7. When (not if) Python 2.7 is no longer supported, big shops can start paying the price that the core Python developers are now paying in supporting the Python 2 code base. Finally, there are a growing list of reasons why Python 3 is simply better than Python 2. I actually would *not* say that Python 3's support for unicode is one of those reasons, but that's debatable. What is not debatable is that Python 3 has cool new features and modules that Python 2.8 will *never* have: - My favorite is pip install, the killer feature of Python 3.4. Yesterday I did "pip install ipython[all]" and everything Just Worked(tm). This is the first time I have *ever* managed to install tornado on Windows, and thus the first time that "ipython notebook" has ever worked on windows. - The important asyncio module https://docs.python.org/3/library/asyncio.html is Python 3 only. Yes, there is a backport to Python 2: https://pypi.python.org/pypi/trollius - Function annotations, https://www.python.org/dev/peps/pep-3107/, will never be part of Python 2 unless they are supported in Python 2.8. - Similarly, the "yield from" syntax, pep 380, https://www.python.org/dev/peps/pep-0380/, will never be part of Python 2. You can quibble about how important these features are (except, pip :-), but there is no doubt that Python 2 is a dead end.

Re: Is it time to develope using Python 3K?
FWIW, I'm pretty pessimistic about Python 3 at this point. Python 2 seems to be "good enough" for most people.

Re: Is it time to develope using Python 3K?
I recently tried to switch to v3, as I remember, I was thwarted by problems having to do with PyQT in a virtualenv. I currently run Leo in a virtualenv, I think I linked to system files to make PyQT work, but I don't remember how I did it. So, I'd like a virtualenv with 3.x Python to run Leo from, but since 'pip install PyQT' doesn't work, I gave up. On Tue, Jan 13, 2015 at 9:54 AM, Edward K.
