<p class=MsoNormal>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 class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>import sys<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>sys.modules['foo'] = type(sys)('foo')<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>import foo<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>Your static analyzer would have a tough time recognizing
that this program would not raise a runtime error.<o:p></o:p></p>

<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>Those things are run-time errors (failed
imports et al). You would<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>possibly look at the parse tree for any
imports and determine if the<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>modules to be imported exist, but that
sounds like a lot of trouble :)<o:p></o:p></span></p>
