Re: [Discuss-gnuradio] [EXT] Re: Python3 or still Python 2.7?

[Chesir, Aaron M.]

Philip, Geof (et al.),

When will a Windows version of GR that supports Python 3 (and complete with 
one-click installers, much like that  advertised for Release 3.7.13.5, below) 
be available?

The reason I prefer to operate within Windows (as opposed to the various 
versions of Linux) is that I can thus avoid the seemingly-endless irritations 
of dependency / incompatibility issues.

Thanks in advance,

Aaron

The GNURadio master branch (which will become 3.8) supports Python3.
