<p>It selects exactly one of the suites by evaluating the expressions one by one
|
|
until one is found to be true (see section <a class="reference internal" href="expressions.html#booleans"><em>Boolean operations</em></a> for the definition of

true and false); then that suite is executed (and no other part of the
|
|
<a class="reference internal" href="#if"><tt class="xref std std-keyword docutils literal"><span class="pre">if</span></tt></a> statement is executed or evaluated). If all expressions are
|

false, the suite of the <a class="reference internal" href="#else"><tt class="xref std std-keyword docutils literal"><span class="pre">else</span></tt></a> clause, if present, is executed.</p>
