Is Py3 ready for prime time? Do all the right libraries have support now?

• vikp 11y ago
  Yes -- I write ~95% of my python code in 3, and scrapy is the only library I commonly use that doesn't support it. Here's a listing of package compatibility: http://py3readiness.org/ http://py3readiness.org/.

  It's been ready for prime time for the past 3 years.

  Unfortunately I'm stuck on 2.7 until Google updates App Engine

    Most of the time I find it pretty easy to make it compatible with both 2.7 and 3.4. Usually just a few "from __future__ import print_function" and a few other tips. If your codebase is large, it can feel daunting, but it's not usually that bad.

  In most cases, yes. There are libraries that you might want to use that don't support it yet but the vast majority do. Personally, I'm anxiously waiting for Fabric 2 which has been pending for a long time.

  Py3 has been prime time for a while now. Been using it full time since Py 3.3 for all my work and I haven't had any issues with it. There were some external libraries such as the library given by a twilio competitor that were incompatible, but easily fixed (almost exclusively, encoding issues). Although, I still find myself running tests and cursing at the fact that I keep writing print "string" without the brackets :D
