Answer :
Alright, let's break down the given code bit by bit to understand what happens when it is executed.
1. Initialization:
`total = 0`
This line initializes a variable `total` to 0. This variable will be used to accumulate a count based on conditions met within the loop.
2. For Loop:
`for i in range(4):`
The `range(4)` function generates a sequence of numbers from 0 to 3 (inclusive), so the loop will run 4 times with `i` taking values 0, 1, 2, and 3 in each iteration.
3. Conditional Statement:
`if 2 i > 4:`
Inside the loop, there’s an `if` statement that checks if `2 i` (twice the current value of `i`) is greater than 4.
- Iteration 1: `i = 0`
`2 0 = 0` which is not greater than 4.
So, `total` remains 0.
- Iteration 2: `i = 1`
`2 1 = 2` which is not greater than 4.
So, `total` remains 0.
- Iteration 3: `i = 2`
`2 2 = 4` which is not greater than 4.
So, `total` remains 0.
- Iteration 4: `i = 3`
`2 3 = 6` which is greater than 4.
Therefore, `total += 1`. Now, `total = 1`.
4. Else Clause:
The `else` clause paired with a `for` loop executes once after the loop has completely finished running all iterations, regardless of the conditions.
`else: total += 1`
Here, after the loop has completed its 4 iterations, `total` is incremented by 1 again.
Therefore, `total = 1 + 1 = 2`.
5. Printing the Result:
`print(total)`
Finally, the `print` statement outputs the value of `total`, which is now 2.
So, when the user runs the code, the output will be:
```
2
```
