$\text{A={Panda,Lion}}$

We find the $\large{subset}$ of sets from $\large{2^n}$

So $\large{2^2=4}$

Hence the answer is $\boxed{4}$ .

Very simple

Since there are 2 elements in $A,$ the number of elements in $P(A)$ is $2^2 = \boxed{4}$

$P(A) = \{\{\text{Lion}\}, \{\text{Panda}\}, \{\text{Panda, Lion}\}, \{\space \}\}$

In the $\text{P(A)}$ where is this $\text{(Lion,Panda)}$ Subset??

$\{\text{Panda,Lion}\}$ is same as $\{\text{Lion,Panda}\}$ .
