This function does the following:
1. Filters out the strings with odd lengths.
2. Sorts the remaining strings first by length and then alphabetically if lengths are the same.
3. Returns the sorted list.

To solve this problem, we need to filter and sort a list of strings based on specific criteria. The goal is to remove strings with odd lengths and then sort the remaining strings by their length in ascending order. If two strings have the same length, they should be sorted alphabetically.

### Approach
1. **Filter the List**: First, we iterate through the input list and remove all strings that have an odd length. This is done using a list comprehension that checks if the length of each string is even.
2. **Sort the Filtered List**: Next, we sort the filtered list. The sorting is done primarily by the length of the strings in ascending order. For strings with the same length, we sort them alphabetically. This is achieved using Python's `sorted` function with a custom key that combines both the length and the string itself.

### Solution Code
```python
def sorted_list_sum(lst):
filtered = [s for s in lst if len(s) % 2 == 0]
return sorted(filtered, key=lambda x: (len(x), x))
```

### Explanation
1. **Filtering Step**: The list comprehension `[s for s in lst if len(s) % 2 == 0]` iterates over each string in the input list and includes it in the new list only if its length is even. This effectively removes all strings with odd lengths.
2. **Sorting Step**: The `sorted` function is used with a lambda function `lambda x: (len(x), x)` as the key. This key ensures that the primary sorting criterion is the length of the string (ascending order). If two strings have the same length, the secondary criterion is alphabetical order, which is handled by comparing the strings themselves.

This approach efficiently combines filtering and sorting to meet the problem requirements, ensuring that the resulting list is both correctly filtered and properly ordered.

gpto1 To complete the given problem, we'll need to follow these steps:
1. Filter out strings with odd lengths from the list.
2. Sort the remaining strings first by their length, and then alphabetically in case of ties.

Here's how you can implement it:

```python
def list_sort(lst):
# Filter out strings with odd lengths
lst_even = [s for s in lst if len(s) % 2 == 0]
# Sort the list by length and then alphabetically
lst_sorted = sorted(lst_even, key=lambda x: (len(x), x))
return lst_sorted
```

**Explanation:**
- We use a list comprehension to create a new list `lst_even` that contains only the strings of even length.
- The `sorted()` function is used to sort the list. The `key` parameter is a lambda function that sorts the strings first by their length (`len(x)`) and then alphabetically (`x`) if the lengths are equal.

**Testing with the examples:**

```python
assert list_sort(["aa", "a", "aaa"]) == ["aa"]
assert list_sort(["ab", "a", "aaa", "cd"]) == ["ab", "cd"]
```

This implementation satisfies all the requirements of the problem, handling any list of strings by removing odd-length strings and sorting the even-length strings appropriately.

In this implementation, the `sorted_list_sum` function:

1. Uses a list comprehension to filter out strings with odd lengths.
2. Sorts the remaining strings by their length and then alphabetically using the `sorted` function with a key that sorts first by length (`len(s)`) and then by the string itself (`s`).

# Remove strings of odd length
lst = [i for i in lst if len(i) % 2 == 0]

Please note that the function first removes strings of odd length, then sorts the list alphabetically, and finally sorts the list by length. This complies with the instruction to sort the list by length first and alphabetically in case of ties. However, since we assume that all words will have the same length, the alphabetical sorting does not impact the result in the provided examples.

minimax The provided function signature and docstring contain a few inconsistencies. The function is named `sorted_list_sum` but the docstring describes a function that should delete strings with odd lengths and return a sorted list. The docstring also mentions that the function should return a list of strings in sorted order, but the example assertions use `list_sort` as the function name. I will correct the function name to match the docstring and provide the implementation accordingly.

This function first filters out any strings with odd lengths using a list comprehension. Then it sorts the remaining strings first by their length and then alphabetically using the `sorted` function with a custom `key` function. The `key` function returns a tuple where the first element is the length of the string (to sort by length) and the second element is the string itself (to sort alphabetically if lengths are equal).

wenxinyiyan The code provided has a few issues and inconsistencies that need to be addressed before it can be completed. First, the function name in the docstring (`list_sort`) does not match the actual function name (`sorted_list_sum`). We should correct this to ensure consistency. Second, the docstring mentions "deletes the strings that have odd lengths from it," but the example assertions seem to suggest that only strings with even lengths should be kept. We will assume that the intent is to keep strings with even lengths based on the examples.

Here's the corrected and completed code:

# Sort the filtered list by length and then alphabetically
sorted_lst = sorted(filtered_lst, key=lambda s: (len(s), s))

return sorted_lst
```
In this code, we first use a list comprehension to create a new list (`filtered_lst`) that contains only the strings from the input list (`lst`) that have even lengths. We achieve this by checking if the length of each string (`len(s)`) is divisible by 2 without a remainder (`len(s) % 2 == 0`).

Next, we use the `sorted` function to sort the filtered list. We pass a `key` parameter to the `sorted` function, which is a lambda function that specifies the sorting criteria. The lambda function takes a string `s` as input and returns a tuple `(len(s), s)`. This means that the list will be sorted first by the length of the strings and then alphabetically if two strings have the same length.

Finally, we return the sorted list (`sorted_lst`).

Note that I have also corrected the assertion statements in the docstring to use the `==` operator instead of `=>` to check for equality.

### Explanation:
1. **Filtering Odd Length Strings**:
- The list comprehension `[s for s in lst if len(s) % 2 == 0]` filters out all strings in the list `lst` that have an odd length.

- The `sorted` function is used with a custom key. The key is a lambda function `lambda x: (len(x), x)` that sorts the strings first by their length and then alphabetically if they have the same length.

3. **Return the Sorted List**:
- The filtered and sorted list is returned.
