if price > 100:
    price = price - 10

Question 8

Which of the following describes the effect of changing the sequence of lines in this code snippet?

Line 1: x = 5
Line 2: x = x + 2
Line 3: if x > 5:
Line 4:     print("Large")

Accepted Answer

If Line 2 is moved to after Line 4, the condition x > 5 is evaluated using the original value of 5, so "Large" would not be printed.

Answer

The order of Line 3 and Line 4 does not matter because they are part of the same selection block.

Answer

Changing the sequence of lines in Python never changes the output as long as all lines are present.

Answer

If Line 1 and Line 2 are swapped, the code will still function exactly the same because the same math is performed.
