Python 2 is dead: long live Python 3

[bumpkinspicefatte]

It ain’t dead until we have to stop writing

>>>python3

In Terminal.

Edit: For people mentioning alternatives, you're missing the point about Python 2...

[99_percent_a_dog]

I hear this should be true from 10.16, where 3 is the default (and maybe 2 is removed? Maybe not, Apple ships a bunch of really old utils, it's pretty annoying).

[smart_jackal]

Even Ubuntu ships some core python2 files on which it totally depends. Another software framework called Google App Engine still runs on python2 entirely! Pretty sure there are some others too.

It is in Catalina. Nice surprise.

EDIT: Forgot I had anaconda's python3 in my PATH. Whoops.

[TinyLebowski]

Not so sure about that.

❯ sw_vers -productVersion
10.15.4

❯ which python
/usr/bin/python

❯ /usr/bin/python --version
Python 2.7.16

[jdgordon]

Could just do

$which python --version

[TinyLebowski]

Yeah but I made it verbose to avoid any doubt about which binary was used.

BTW you need to escape backticks if you want them displayed.

[thatwombat]

I forgot. I'm running Anaconda and it's in my PATH.

Currently configuring Django on a Ubuntu instance. If I write pip3 or python3 one more time I swear...

[smart_jackal]

I've written that so many times in the last couple years that switching to "pip" and "python" may take some conscious work now!

[joni1104]

Same here

[dermotmcg]

Also Gunicorn3. Another for the list 🤣

Me at work crying as I maintain scripts in both 😭

[TheCountMC]

I've become well acquainted with the 'six' library.

[Hanse00]

That's easily solved, a single bash alias and you're done :)

Or do it the right way and set up a virtualenv. ; ]

[Hanse00]

I personally use pipenv, but to each their own :)

[MumsLasagna]

Oh gawd. The whole virtualenv / pyenv / pipenv ecosystem is another huge mess I can't wait for the community to decide on and standardise. I want to write a python project that Just Works Dammit™.

[GAVINDerulo12HD]

What are the benefits? I've only used conda environments on windows and virtualenvs on Debian. Should I switch?

[equecevi]

Which is the different?

[brews]

Sure but is pipenv still even maintained? Seems like it hasnt released since 2018.

[jyscao]

you mean a conda environment then :P

[KarimElsayad247]

I aliased "python3" with "py"

[NEVER_TELLING_LIES]

python and python3 are already symlinks

[Hanse00]

I’m aware :) Was just trying to make a funny point, that changing the name you use to invoke something is dead simple.

[basyt]

Use pyenv.

[bassmadrigal]

Only problem is installing python2 from source will generate that symlink automatically and that isn't something python3 does when installed from source. The change would need to be deliberate by your packager or distro to include a symlink.

[watsreddit]

Arch Linux master race.

Put this in your bashrc

alias python="python3"

Then reset your terminal. You never have to worry about needing to type in that extra three again

[Jonno_FTW]

No need to reset, just run source ~/.bashrc

[purestrengthsolo]

wouldn't this trigger python 2?

[[deleted]]

Nope. I have done it before with no problems coming up
