is-empty-iterable:检查Iterable是否为空
Iterable argument unpacking is a feature in Python that allows you to unpack the elements of an iterable object, such as a list or a tuple, into individual arguments. It follows the keyword argument unpacking, which allows you to unpack a dictionary into keyword arguments. This feature was introduced in Python 3.5 as PEP 448 for more concise and flexible function calls.
To use iterable argument unpacking, you can prefix the iterable object with an asterisk (*) in the function call. For example:
```python
def my_func(a, b, c):
print(a, b, c)
my_list = [1, 2, 3]
my_func(*my_list) # Unpacking the list with iterable argument unpacking
```
In this case, the elements of `my_list` will be unpacked and passed as separate arguments to the `my_func` function. It will print `1 2 3`.
Note that iterable argument unpacking can only be used for positional arguments, while keyword argument unpacking can only be used for keyword arguments. They cannot be mixed in the same function call.
