Question
### Task

**Objective:**
Create the function `Sum`, which when called, returns the sum of all the integers preceding and inclusive of the integer passed in its argument.

**For Example:**
When the function `Sum(4)` is called, it should return `10`.

**Instructions:**
1. Define the function `Sum`.
2. Ensure that when called with an integer `n`, the function returns the sum of all integers from `1` to `n`.
3. Provide a screenshot of your code along with its output to demonstrate its functionality.

### Example Code:

```python
def Sum(n):
    return sum(range(1, n + 1))

# Example Usage
result = Sum(4)  # Expected output is 10
print(result)    # Prints 10
```

**Explanation:**
- The function `Sum` uses Python’s built-in `sum()` function to calculate the sum of a range of numbers.
- `range(1, n + 1)` generates a sequence of numbers from 1 to `n` inclusive.
- The `sum()` function then adds up all these numbers and returns the result.

### Expected Output:
When you run the code above with the input `4`, the output should be `10`, as it calculates `1 + 2 + 3 + 4 = 10`.

### Screenshot:
Make sure to attach a screenshot of your code and its output as a demonstration. 

This exercise is helpful in practicing the creation of simple functions and understanding the use of fundamental built-in functions in Python.
