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]
