Final answer:
The output of the given snippet is 2.
Step-by-step explanation:
The output of the given snippet is 2.
To understand why, let's break down the code:
- The function fun(x) takes an argument x.
- If x is truthy (meaning it evaluates to True), the function returns 1.
- Otherwise, the function prints 'fun' and returns None.
- Now, let's evaluate the expression fun(fun(2)) + 1:
- fun(2) is called first. Since 2 is truthy, the function returns 1.
- Next, fun(1) is called. Again, 1 is truthy, so the function returns 1.
- Finally, 1 + 1 is evaluated, resulting in 2.
Therefore, the output of the snippet is 2.
