Diagnosing a Linux-only unit test failure

Note that you can do this in old version of Python, too, using the "format-locals" idiom:

    some_var = ...

    "{some_var}".format(**locals())

Although this does have some limitations regarding variables to strictly being in the local scope, this is a fine idiom if you need to be compatible with older Python versions.

That is a bit of a hack though ;). You could also do it with %-style formatting as well:

  some_var = ...
  "%(some_var)s" % locals()

If you want to do both locals and globals you can do:

  some_var = ...
  "%(some_var)s" % dict(globals(), **locals())

New Python versions (>=3.5) have this syntax:

  "%(some_var)s" % {**globals(), **locals()}

But those versions also have f-strings so that's sort of moot.
