In Python, you can use type hints for *args
and **kwargs
to indicate the types of the arguments they represent. Here's how you can specify type hints for them:
*args
:from typing import Tuple, Any
def example_function(*args: Tuple[Any, ...]) -> None:
# Your function code here
**kwargs
:from typing import Dict, Any
def example_function(**kwargs: Dict[str, Any]) -> None:
# Your function code here
By using these type hints, you can provide better documentation and help developers understand the expected types of the variable-length arguments. Note that Any
in the type hints allows for any type to be passed. You can also replace it with more specific types if needed.
Python function that uses both *args
and **kwargs
with type hints:
from typing import Tuple, Dict, Any
def example_function(*args: Tuple[int, str], **kwargs: Dict[str, Any]) -> None:
for arg in args:
arg_index, arg_value = arg
print(f"Argument at index {arg_index}: {arg_value}")
for key, value in kwargs.items():
print(f"Keyword argument '{key}': {value}")
In this example, the example_function
takes a variable number of positional arguments of type (int, str)
represented by *args
. It also takes a variable number of keyword arguments of any type represented by **kwargs
. The function then iterates through args
and kwargs
to print their values and respective indices or keys. The type hints help to clarify the expected types for both types of arguments.
