Question

Look at the following function definition: def do_something(number): return number * 2 a. What is the name of the function? b. What does the function do? c. Given the function definition, what will the following statement display? print(do_something(10))

Short answer

Answer: The name of the function is "do_something". The function doubles its input. The output of the statement "print(do_something(10))" is 20.

Step-by-step solution

Identifying the function's name

The function's name is the first thing that comes after the "def" keyword. In this case, we can see that the name of the function is "do_something".

Understanding the function's purpose

To understand what the function does, we need to look at the code inside the function. Here, we see a single line of code: "return number * 2". This means that the function takes an input (called "number") and returns the result after multiplying the input by 2. The function essentially doubles its input.

Evaluating the given statement

We're given a statement to evaluate: "print(do_something(10))". We need to substitute the number 10 into the function "do_something" and compute the result. Since we know that the function doubles its input, the result will be 10 * 2 which equals 20. So, the output displayed by the statement will be 20.
