Question

Identify five errors in this program, which is supposed to take the average (mean) of three numbers:

define average(one, two, three):
avg = one + two * three
return aver

print("The average of 6, 7, and 8 is: ," average(6, 7, 8))

Answer 1

Here are five errors in the provided program that is intended to calculate the average (mean) of three numbers:

1. **Function Definition Syntax**: The function definition should use the `def` keyword properly. The function should be defined with proper syntax like `def average(one, two, three):`. However, if this were part of a Python code, it's needed to ensure proper indentation for the function body.

2. **Incorrect Average Calculation**: The formula used to calculate the average is incorrect. The average of three numbers should be computed as:
```python
avg = (one + two + three) / 3
```
The provided formula `avg = one + two * three` does not calculate the average.

3. **Variable Name Mismatch**: The return statement uses `return aver`, but the variable defined in the function is named `avg`. It should be:
```python
return avg
```

4. **Print Function Syntax**: The print function has incorrect syntax. The comma before the function call is misplaced. It should be:
```python
print("The average of 6, 7, and 8 is:", average(6, 7, 8))
```

5. **Output Format**: While not strictly an error, to improve clarity, you might want to format the output better, potentially using an f-string (if using Python 3.6 or later) or format method to include the result in a more readable way. However, this is optional based on style preference.

### Corrected Code:
```python
def average(one, two, three):
avg = (one + two + three) / 3
return avg

print("The average of 6, 7, and 8 is:", average(6, 7, 8))
```

With these corrections, the program would correctly calculate and print the average of the three numbers.
