You are an expert programmer. Solve the task exactly as specified. Output your solution as fenced code blocks using the required file name(s) and the exact function/type signatures requested. Prefer correctness; do not include prose outside code unless asked.

To solve this problem, we need to create a function that takes a list of integers and returns a tuple containing the sum and product of all the integers in the list. The function should handle both non-empty and empty lists appropriately.

### Approach
1. **Sum Calculation**: Use Python's built-in `sum()` function to calculate the sum of the list. This function handles empty lists by returning 0, which meets our requirement.
2. **Product Calculation**: Initialize a variable to 1 (since the product of an empty list should be 1). Loop through each number in the list, multiplying each number to this variable to get the product.
3. **Return Tuple**: Combine the calculated sum and product into a tuple and return it.

This approach ensures that both the sum and product are calculated efficiently and correctly, including handling edge cases for empty lists.

### Solution Code
```python
from typing import List, Tuple

def sum_product(numbers: List[int]) -> Tuple[int, int]:
    total_sum = sum(numbers)
    product = 1
    for num in numbers:
        product *= num
    return (total_sum, product)
```

### Explanation
- **Sum Calculation**: The `sum()` function is used to compute the sum of the list elements. For an empty list, `sum()` returns 0, which is the desired behavior.
- **Product Calculation**: We initialize `product` to 1. By iterating over each element in the list and multiplying each element to `product`, we compute the product of all elements. If the list is empty, the loop does not run, and `product` remains 1, which is the correct behavior.
- **Return Value**: The function returns a tuple where the first element is the sum and the second element is the product of the list elements.

This solution efficiently handles all cases, including empty lists, and ensures correct results for both sum and product calculations.

Okay, I need to solve this Python problem. Let's read the task carefully.

The function is called sum_product and takes a list of integers. It should return a tuple with two elements: the sum of all integers and the product of all integers in the list.

Hmm, wait, what about edge cases? Oh right, the problem says that the empty sum is 0 and the empty product is 1. So if the list is empty, return (0, 1).

Let me think about how to calculate the sum and product.

For the sum, I can use the built-in sum function. That's straightforward.

For the product, I need to multiply all the numbers together. How to do that? Well, I can initialize a variable to 1 and then loop through each number, multiplying them one by one.

Wait, but what if the list is empty? Then the product is 1, which is already handled by the initial value.

So the steps are:

1. Check if the list is empty. If yes, return (0, 1).
2. Otherwise, calculate the sum using sum(numbers).
3. Calculate the product by iterating through each number and multiplying them.
4. Return the tuple (sum, product).

Wait, but in Python, the sum of an empty list is 0, so maybe I don't need a special case for that. Similarly, for the product, initializing to 1 and multiplying all elements will handle the empty case because the loop won't run, leaving product as 1.

So I can write the function without checking if the list is empty. Let's see:

def sum_product(numbers: List[int]) -> Tuple[int, int]:
    total_sum = sum(numbers)
    product = 1
    for num in numbers:
        product *= num
    return (total_sum, product)

Yes, that should work.

Testing the examples:

sum_product([]) should return (0, 1). Let's see:

sum([]) is 0, product is 1. Correct.

sum_product([1,2,3,4]) should return (10,24). Sum is 1+2+3+4=10, product is 1*2*3*4=24. Correct.

What about a list with one element? Like [5]. Sum is 5, product is 5. That's handled.

What about negative numbers? Let's say [-1, 2]. Sum is 1, product is -2. The code should handle that.

So I think this solution should work.
