tep-by-Step Explanation:

Variable Initialization:
```
a = 10
```
- You define a variable a with the value 10.
Function Call:
```
modify(a)
```
- The function modify is called with a as the argument.
- Inside the function, x = a, so x = 10.
Inside the Function:
```
x = x + 5
```
- This creates a new local variable x inside the function.
- It adds 5 to x, making x = 15, but this does NOT affect the original a outside the function.
Printing a:
```
print(a)
```
- a still holds the original value 10, because integers are immutable in Python and reassignment inside the function doesn’t change the original variable.

✅ Output:

Key Concept:

Python uses pass-by-object-reference, and integers are immutable. So when you modify a number inside a function, it does not affect the original variable.
