In Python, args and **kwargs are used to pass a variable number of arguments to a function.
1. args:
– Used to pass a variable number of non-keyword arguments (positional arguments) to a function.
– It collects extra positional arguments into a tuple.
Example:
python
def example(*args):
for arg in args:
print(arg)
example(1, 2, 3) # Output: 1 2 3
*2. **kwargs**:
– Used to pass a variable number of keyword arguments (named arguments) to a function.
– It collects extra keyword arguments into a dictionary.
Example:
python
def example(**kwargs):
for key, value in kwargs.items():
print(f”{key}: {value}”)
example(a=1, b=2) # Output: a: 1 b: 2
Key Differences:
– args handles positional arguments, while **kwargs handles keyword arguments.
– args is a tuple, and **kwargs is a dictionary.
Both allow flexibility in function calls, accommodating varying numbers of arguments
