## 最终结论
```python
def empty_dit(lst):
    if not isinstance(lst, list):
        return False
    for item in lst:
        if not isinstance(item, dict) or item:
            return False
    return True

# Test cases
assert empty_dit([{},{},{}])==True
assert empty_dit([{1,2},{},{}])==False
assert empty_dit({})==False
```
