• show is in its early days. Over time, it will provide additional context-specific output helpers. For example, the “diff” views of py.test seem a high-value enhancement.
  • show depends on introspection, with its various complexities and limitations. It assumes that all objects are new-style classes, and that your program has not excessively fiddled with class data. Diverge from these assumptions, and all bets are off.
  • Automated multi-version testing managed with the wonderful pytest and tox. Successfully packaged for, and tested against, most late-model versions of Python: 2.7, 3.3, 3.4, 3.5, and 3.6, as well as PyPy 5.6.0 (based on 2.7.12) and PyPy3 5.5.0 (based on 3.3.5).
