575.2.3.3 What's the Execution Context?
58</H3>
59
60<P>
61By default, each time <tt class="module"><a href="module-doctest.html">doctest</a></tt> finds a docstring to test, it
62uses a <em>shallow copy</em> of <tt class="module">M</tt>'s globals, so that running tests
63doesn't change the module's real globals, and so that one test in
64<tt class="module">M</tt> can't leave behind crumbs that accidentally allow another test
65to work. This means examples can freely use any names defined at top-level
66in <tt class="module">M</tt>, and names defined earlier in the docstring being run.
67Examples cannot see names defined in other docstrings.
68
69<P>
70You can force use of your own dict as the execution context by passing
71<code>globs=your_dict</code> to <tt class="function">testmod()</tt> or
72<tt class="function">testfile()</tt> instead.
