This quiz question tests your understanding of unpacking tuples in function arguments in Python.

You should know how to use the `*`

operator to unpack tuples and handle function parameters effectively.

## Question: Tuples in Function Arguments

Consider the function `calculate_area`

which takes two parameters, `length`

and `width`

, and returns the area of a rectangle.

You have a tuple `dimensions`

containing the length and width of a rectangle.

```
def calculate_area(length, width):
return length * width
dimensions = (5, 10)
```

Which of the following code snippets **incorrectly** uses the `calculate_area`

function to calculate the area using the values in the `dimensions`

tuple?

**Option A** is the correct answer.

**Explanation**: The function`calculate_area`

expects two separate arguments,`length`

and`width`

, but this code passes a single tuple, leading to a`TypeError`

.**Result**:

```
Traceback (most recent call last):
File "<pyshell#12>", line 1, in <module>
area = calculate_area(dimensions)
TypeError: calculate_area() missing 1 required positional argument: 'width'
```

**Option B**:

**Reason for Incorrectness**: The`*`

operator unpacks the tuple into separate arguments, so`calculate_area`

receives`5`

as`length`

and`10`

as`width`

.- This is the correct and concise way to call the function with the values in the tuple.
**Result**:`area = 50`

**Option C**:

**Reason for Incorrectness**: This correctly unpacks the tuple into individual values for`length`

and`width`

.- However, it unnecessarily complicates the code with explicit indexing when the unpacking (
`*`

) operator is more straightforward. **Result**:`area = 50`

(but not the preferred method)

**Option D**:

**Reason for Incorrectness**: This code unpacks the tuple into two variables,`length`

and`width`

, and then calls`calculate_area`

with these variables.- This method is correct and clear, showing a good understanding of tuple unpacking.
**Result**:`area = 50`
