### " *paramter "
|
||
|
||
> 表示接收任意多个实际参数，并将其放到一个元组中。
|
||
|
||
- **传递任意数量的参数**
|
||
|
||
**示例代码**：
|
||
```python
|
||
def func_1(*items):
|
||
print(items)
|
||
print(type(items))
|
||
|
||
# 传递任意数量的参数
|
||
func_1(1,2,3,45,"ffff")
|
||
```
|
||
|
||
- **以列表形式传递参数**
|
||
|
||
**响应结果**：
|
||
```python
|
||
(1, 2, 3, 45, 'ffff')
|
||
<class 'tuple'>
|
||
```
|
||
**示例代码**：
|
||
```python
|
||
def func_1
|
||
list_1 = [1, 2, 3, 45, 'ffff','aaaa']
|
||
|
||
以列表形式传递参数
|
||
func_1(*list_1)
|
||
```
|
||
**响应结果**：
|
||
```python
|
||
(1, 2, 3, 45, 'ffff', 'aaaa')
|
||
<class 'tuple'>
|
||
```
|
||
|
||
### " **paramter "
|
||
|
||
> 表示接收任意多个实际参数，并将其放到一个字典中。
|
||
|
||
- **直接传入键对值调用**
|
||
|
||
**示例代码**：
|
||
```python
|
||
def func_2(**params):
|
||
print(params)
|
||
print(type(params))
|
||
func_2(a=1, b=6,c=9)
|
||
```
|
||
**响应结果**：
|
||
```python
|
||
{'a': 1, 'b': 6, 'c': 9}
|
||
<class 'dict'>
|
||
```
|
||
|
||
- **通过字典传输可变参数**
|
||
|
||
**示例代码**：
|
||
```python
|
||
dict_1 = {"a":1,"b":2,"c":3}
|
||
func_2(**dict_1) # 通过字典，对可变参数传值
|
||
```
|
||
**响应结果**：
|
||
```python
|
||
{'a': 1, 'b': 2, 'c': 3}
|
||
<class 'dict'>
|
||
```
