号=42,串=约翰
创建一个函数,它需要两个参数,一个字符串和一个数字,然后输出"数字是[数]和字符串是[字符串]".
Here is an example of how the function can be created in Python:

```python
def string_and_number(number, string):
    return f"The number is {number} and the string is {string}"
```

Using the above `string_and_number()` function with the input values `number=42` and `string="John"`, the output would be:
```python
string_and_number(42, "John")
>>> "The number is 42 and the string is John"
```
