<em>6.65 </em><em>is displayed as the</em><em> output </em><em>of the </em><em>block of code</em>
<em />
In python programming, * denotes multiplication. To get the output, we will substitute the value of x and y given into the result to have;
<em> result = x * y - x / (y)</em>
<em> result = 7 * 20 - 7 / (20)</em>
<em> result = 140 - 7 / (20)</em>
<em> result = 133/20</em>
<em> result = 6.65</em>
<em />
<em>This shows that </em><em>6.65 </em><em>is displayed as the</em><em> output </em><em>of the </em><em>block of code</em>
<em />
The question is incomplete;
Let the code segment be
<em>>>> x = 7
</em>
<em>>>> y = 20
</em>
<em>>>> result = x * y - x / (y)
</em>
<em>>>> result </em>
<em>output:__?</em>
