Multiple Choice Questions related to Functions in Python
In Python, a function is a block of code that performs a specific task and can be reused throughout a program. Functions are defined using the "def" keyword, followed by the function name and a set of parentheses. The code that the function executes is indented below the function definition.

Here is an example of a simple function in Python that takes two numbers as inputs and returns their sum:

```
def add_numbers(a, b):
sum = a + b
return sum
```

In this example, the function is named "add_numbers" and takes two arguments, "a" and "b". The function adds the two numbers together and stores the result in the variable "sum". The "return" keyword is used to return the value of "sum" to the calling code.

To call the function, you simply write the function name followed by the arguments in parentheses:

```
result = add_numbers(3, 5)
print(result) # Output: 8
```

Functions in Python can have optional arguments, default values for arguments, and can return multiple values using tuples. They are useful for breaking down complex tasks into smaller, more manageable pieces of code, and can simplify code reuse and maintenance.

It is important to properly name and document your functions to make them easier to understand and use by other programmers who may be working with your code.
