"IF NOT"

I'm trying to understand exactly what the code is asking?

x = 4 y= 2 if not 1 + 1 == y or x == 4 and 7 == 8: print("Yes") elif x > y: print("No")

I'm confused about what an "if" statement is asking of a Boolean.

This looks like a test of your understanding of operator associativity.

The "not" part of this expression just inverts the result of the comparison "1 + 1 == y" so the entire thing means "if y is not equal to 2".

Everything after the "or" in the larger expression is meaningless since 7 will never equal 8.

Great explanation! that gives me much more clarity. Whenever the code can be "translated" that helps every time. thanks!
