Consider the following function:
def w(x, y) :
   z = x + y 
   return z
What is the function's name?

The question asks us to identify the name of the function defined in the given code snippet.
First, observe the function definition line: def w(x, y):. Here, def introduces a function, w is the identifier immediately after def, and (x, y) are its parameters. This clearly indicates that the function's name is w, not any of the other symbols shown later in the body.
Next, consider the subsequent lines inside the function body. The line z = x + y assigns a value to the variable z, and return z outputs that value when the function is called. These names (z) are variables local to the function’s body and do not represent the function’s name.
Now, evaluate each answer option:
- z: This is a local variable used to store the sum x + y, not the function's name. It appears only inside the function body and has no bearing on the function’s identifier.
- x: This is a parameter of the function, one of the inputs it accepts. While it is a name used in the function, it is not the function’s name.
- y: Similar to x, this is also a parameter of the function, not its name. It participates in calculations inside the function, but does not identify the function itself.
- w: This is the identifier that follows def, making it the function’s name. It is the label you would use to call the function elsewhere in the code (e.g., w(1, 2)).
In summary, the only option that corresponds to the function’s actual identifier is w, since def w(x, y): designates w as the function’s name while z, x, and y serve other roles within the function structure.
