The output will be:
X: 6 Y: 8 Z: 10
Let's break down the code step by step:
1. `x, z = 5, 10`: Assigns the values 5 and 10 to variables x and z, respectively.
2. `y = x + 3`: Assigns the value of x + 3 (5 + 3 = 8) to the variable y.
3. `x = x - 1`: Subtracts 1 from the current value of x (5 - 1 = 4) and reassigns it to x.
4. `x = x + 2`: Adds 2 to the current value of x (4 + 2 = 6) and reassigns it to x.
5. `print('X:', x, 'Y:', y, 'Z:', z)`: Prints the values of x, y, and z. At this point, x is 6, y is 8, and z is 10. Therefore, the output will be "X: 6 Y: 8 Z: 10".
