Answer / Dhiraj Singh
In Python, variables are passed by object reference. This means that when you pass a variable to a function, the function receives a reference to the original variable, not a copy of it. Here's an example:
```python
def increment(n):
n += 1
x = 5
increment(x)
print(x)
# Output: 5 (Python doesn't change the value of x inside the function)
```
