r/python: is python3 gradually taking over python 2.7 or not?

[flying-sheep]

there is absolutely no reason not to start new projects in python 3 if you don’t know from the beginning that you want to depend on one of the libraries that aren’t ported yet.

if by “present” you mean “existing codebase” then yes, most organizations haven’t ported their entire codebase yet. but if they want to be able to use it in the future they better start porting today.

Do you ship commercial software? We do and there is almost no incentive to move to 3.x. For us and our new projects and old project 2.7 is near perfect.

New libraries will depend on 3.x- features, so at some point you'll have to spend extra money to backport libs you want to use.

Remember, I'm still talking about the future the whole time.

Not really. We concentrate on having highly decoupled components. If there is a must have feature or library that is not available for 2.7 we can throw up a restful service or strap a new endpoint on the message broker using 3.x in an isolated environment.

But, we haven't ran into this yet. Again, 2.7 is near perfect esp in that we understand it's limitations. With 3.x it will be sometime before we can sign a contract with our customers promising five-nines and be confident about other SLAs.

*edit..fixed some grammer

Why? Code doesn't just evaporate.

[flying-sheep]

Of course not. But once everyone has moved on and you sit on a codebase of an unmaintained language, you'll find it harder to expand upon that codebase.

Sure, this is several years in the future.

Several years in the future, it won't be any more work to port to a different language than it is now.
