What is the output of the following Python code?

[tex]$
\begin{array}{l}
\gg \text{tupleB} = (5, 7, 5, 10, 2, 7) \\
\gg \text{tupleB.count(7)}
\end{array}
$[/tex]

A. 2
B. 1
C. 5
D. 0



Answer :

To determine which line is next, we should understand what the previous lines are instructing us to do. We already have:

[tex]\[ \begin{array}{l} \gg \text { tupleB }=(5,7,5,10,2,7) \\ \gg \text { tupleB.count(7) } \end{array} \][/tex]

Given this, the instruction `tupleB.count(7)` asks us to count how many times the element `7` appears in the tuple `(5, 7, 5, 10, 2, 7)`.

As we see in the tuple:
- The number `5` appears twice.
- The number `7` appears twice.
- The number `10` appears once.
- The number `2` appears once.

The count of the number `7` in the tuple is `2`.

Therefore, the next line, which is the result of `tupleB.count(7)`, should be:
[tex]\[ 2 \][/tex]
