Final answer:
The Python function 'test' is called with the argument 10. It adds 5 to this argument, resulting in 15, which is then printed out.
Step-by-step explanation:
The given Python function test takes a parameter x, adds 5 to it, and then prints the result. When we call test(10), the function adds 5 to the argument 10, resulting in 15. Thus, it prints out 15 as the output.
The output of the given code is 15.
The code defines a function named test that takes a parameter x. Inside the function, x is incremented by 5. Then, x is printed, resulting in the output of 15 when the function is called with the argument 10.
