The given Python code defines a recursive function `demo(p, q)`. This function checks if `p` is equal to 0. If `p` is 0, it returns `q`. Otherwise, it calls itself with parameters `p-1` and `p+q`.

Let's break down the execution of `demo(4,5)`:

1. `demo(4,5)` is called. Since `p` is not 0, it calls `demo(3, 4+5)` which is `demo(3,9)`.
2. `demo(3,9)` is called. Since `p` is not 0, it calls `demo(2, 3+9)` which is `demo(2,12)`.
3. `demo(2,12)` is called. Since `p` is not 0, it calls `demo(1, 2+12)` which is `demo(1,14)`.
4. `demo(1,14)` is called. Since `p` is not 0, it calls `demo(0, 1+14)` which is `demo(0,15)`.
5. `demo(0,15)` is called. Since `p` is 0, it returns `q` which is 15.

So, the output of the Python code will be `15`.

swerWhat will be the output of the following Python code?def demo(p,q): if(p == 0): return q else: return demo(p-1,p+q)print(demo(4,5))
