Recursion is a way of solving a problem where a function calls itself to solve smaller versions of the same problem.

A recursive function usually has two parts:

1. **Base case** — when to stop  
2. **Recursive case** — calling itself with a smaller input

Example: calculating `3!` factorial.

```python
def factorial(n):
    if n == 1:          # base case
        return 1
    else:
        return n * factorial(n - 1)  # recursive case
```

Calling:

```python
print(factorial(3))
```

This works like:

```python
factorial(3) = 3 * factorial(2)
factorial(2) = 2 * factorial(1)
factorial(1) = 1
```

So:

```python
3 * 2 * 1 = 6
```

Recursion is useful when a problem can be broken into smaller repeated subproblems.
