#5 How to Add Any Number of Arguments with *args | Python Function | Python Tutorial for Beginners
@yasirbhutta In this video, we explore a powerful feature in Python — the ability to pass a variable number of arguments to a function using `*args`. We define a function called `add()` that takes in any number of arguments and sums them up, no matter how many numbers you provide.
Here’s the code we’ll be working with:
```python
def add(*args):
total = 0
for n in args:
total += n
return total
```
With this `add()` function:
You can pass multiple numbers to be added together.
You can pass any number of arguments (or none at all).
It will handle different input scenarios gracefully, whether you provide several numbers or none.
Example Usage:
```python
print(add(1, 2, 3)) # Output: 6
print(add(4, 5)) # Output: 9
print(add(6)) # Output: 6
print(add()) # Output: 0
```
This is a great introduction to using `*args` in Python to work with variable-length argument lists. Whether you're summing numbers or dealing with flexible inputs, understanding how to use `*args` can make your functions more dynamic and adaptable.
