<p>The only reliable way to find if a particular program returns a runtime
error is to execute the program. For limited, targeted cases, (such as
importing modules) you could write an analyzer program which would be *often*
right -- but I could create a program that tricks your analyzer into
reporting a problem where none exists. Consider this:<o:p></o:p></p>
</div>
<div>
<p> <o:p></o:p></p>
</div>
<div>
<p>import sys<o:p></o:p></p>
</div>
<div>
<p>sys.modules['foo'] = type(sys)('foo')<o:p></o:p></p>
</div>
<div>
<p>import foo<o:p></o:p></p>
</div>
<div>
<p> <o:p></o:p></p>
</div>
<div>
<p>Your static analyzer would have a tough time recognizing that this program
would not raise a runtime error.<o:p></o:p></p>

<p><span lang=EN-US>Those things are run-time errors (failed imports et al).
You would</span><o:p></o:p></p>
<p><span lang=EN-US>possibly look at the parse tree for any imports and
