Question

Определи значение переменной z после выполнения фрагмента программы. x = 3 y = 34 y -= 2 * x if x > y: z = x + y else: z = x - y Впиши верное значение.

Answer 1

Ответ:

-25

Объяснение:

x = 3

y = 34

y -= 2 * x = y - 2 * x = 34 - 2 * 3 = 34 - 6 = 28

if x > y: z = x + y (3 > 28 - условие ложно эта ветка не выполняется)

else: z = x - y = 3 - 28 = -25

Answer 2

Understanding the Code Fragment

The given code fragment assigns values to variables `x` and `y` and then performs a conditional statement using the `if-else` construct. Based on the comparison between `x` and `y`, the variable `z` is assigned a value.

Let's break down the code and determine the value of `z` after executing the code fragment.

1. Assigning Values to Variables: - `x = 3` - `y = 34`

2. Conditional Statement: - `if x > y:`

3. Execution Based on the Conditional Statement: - If `x` is greater than `y`, then `z` is assigned the value of `x + y`. - If `x` is not greater than `y`, then `z` is assigned the value of `x - y`.

Determining the Value of `z`

To determine the value of `z`, we need to compare the values of `x` and `y` and execute the appropriate branch of the conditional statement.

In this case, `x` is 3 and `y` is 34. Since 3 is not greater than 34, the code will execute the `else` branch of the conditional statement.

Therefore, the value of `z` after executing the code fragment is -31.

Example Execution:

Here's an example execution of the code fragment to illustrate the process:

x = 3
y = 34

if x > y:
    z = x + y
else:
    z = x - y

print(z)

Output: ``` -31 ```
