What will be the output for following code snippet?x=5x=y-=1print(y)810Syntax errorNo error but no output

The code snippet you provided has a syntax error.

Here's the step by step explanation:

1. x=5 - This is a valid statement where you're assigning the value 5 to the variable x.

2. x=y-=1 - This is an invalid statement. It seems like you're trying to use the decrement operator (-=) but it's not used correctly. If you're trying to subtract 1 from y and then assign the result to x, you should first ensure that y is defined, then do the operations separately like this:

y = some_value
y -= 1
x = y

3. print(y) - This will print the value of y to the console. But in your original code, y is not defined before you try to subtract 1 from it, so this will also result in an error.

So, the correct answer is "Syntax error".
