﻿ Python Function: Calling functions with flexible arguments

# Python Function: Calling functions with flexible arguments

## Python ellipsis (...) Data Type: Exercise-2 with Solution

Write a Python function that takes a function as an argument and calls it with any number of arguments.

Sample Solution:

Code:

``````def call_function(func, *args, **kwargs):
"""
Calls the given function with any number of positional and keyword arguments.

Args:
func (function): The function to call.
*args: Any positional arguments to pass to the function.
**kwargs: Any keyword arguments to pass to the function.

Returns:
The result of calling the function.
"""
return func(*args, **kwargs)

# Example usage:
return x + y

print(result)  # Output: 8

def message(name, text="Good Evening"):
return f"{name}, {text}!"

result = call_function(message, "Erich", text = ...)
print(result)
``````

Output:

```32
Erich, Ellipsis!
```

In the exercise above, the "call_function()" function takes a 'func' argument, which is the function to call, and uses *args and **kwargs to accept any number of positional and keyword arguments. It then calls 'func' with these arguments and returns the result. As a result, you can call different functions with different numbers of arguments by using the same "call_function ()".

In this code, the ellipsis (...) is used as a placeholder for unspecified arguments in the function calls 'add' and 'message'. It indicates that there can be additional positional or keyword arguments.
