Right now most of the dart SDK's python is compatible with python2 or python3. This change fixes a few of the build scripts to make that completely true (at least when building the standard build on Linux). There are only four types of changes: - Bare `print` statements now use the `print ()` function - `commands.getoutput` becomes `subprocess.check_output` with `shell=True` - `xrange` becomes `range` - `print >> sys.stderr` becomes `sys.stderr.write` Starts work on addressing (but does not completely fix): https://github.com/dart-lang/sdk/issues/28793 See related issue: https://fuchsia-review.googlesource.com/c/fuchsia/+/272925 This change applys to both the `dev` and `master` branches.
