What are Python’s *args and **kwargs?

Question

ICSM · Answer

1. *args (Non-keyword arguments)
This is used to pass a variable number of accepted arguments to a function. Inside the function,
args is treated as a tuple.
Example:
def sum_numbers(*args):
    return sum(args)
print(sum_numbers(1, 2))         # 3
print(sum_numbers(1, 2, 3, 4))   # 10
Here, *args lets the function many number of positional values as arguments.
2. **kwargs (Keyword arguments)
This is used to pass a variable number of keyword arguments (key=value) pair to a function. Inside the function,
kwargs is treated as a dictionary.
Example:
def show_details(**kwargs):
    for key, value in kwargs.items():
        print(f"{key}: {value}")
show_details(name="Alice", age=25, city="New York")
Output:
name: Alice
age: 25
city: New York
3. Using *args and 
**kwargs together
This can use both in the same function, but *args must come 
before **kwargs.
Example:
def show_information(*args, **kwargs):
    print("Positional:", args)
    print("Keyword:", kwargs)
show_information(10, 20, 30, name="Alice 2", age=85)
Output:
Positional: (10, 20, 30)
Keyword: {'name': 'Alice 2', 'age': 85}
4. Argument unpacking
This can also use * and ** when calling functions to
unpack values.
Example:
def greet(name, age):
    print(f"Hello {name}, you are {age} years old.")
args = ("Bob", 30)
kwargs = {"name": "Charlie", "age": 40}
greet(*args)      # Hello Bob, you are 30 years old.
greet(**kwargs)   # Hello Charlie, you are 40 years old.
In short:
*args → collects extra positional arguments into a tuple.**kwargs → collects extra keyword arguments into a dictionary.They make functions more flexible and reusable.
