Certainly! Here is the code you requested:
```python
singleton_tuple = ("apple",)
singleton = ("apple")
print(type(singleton_tuple))
print(type(singleton))
```
After running the code and printing the types of `singleton_tuple` and `singleton`, you will notice the following difference:
- The type of `singleton_tuple` is `tuple`. This is because it is defined with a trailing comma, indicating that it is a tuple with a single element.
- The type of `singleton` is `str`, not a tuple. This is because it does not have a trailing comma and is interpreted as a string instead.
The trailing comma in `singleton_tuple = ("apple",)` is crucial to differentiate it from a string. In Python, a tuple with a single element requires a comma after the element to be recognized as a tuple. Otherwise, it will be treated as a different type, such as a string in this case.
