I’m extremely confused, please do answer in detail..

Question

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

• Yes
• No
• Yes No

Answer 1

In:
not 1+1==2 or 4==4 and 7==8

+ operations have the highest operation precedence, thus + operations are evaluated first:

1+1 ---> 2

We get:
not 2==2 or 4==4 and 7==8

Where the comparison operators have the highest operation precedence, let's evaluate the comparison operations:
2==2 ---> True
4==4 ---> True
7==8 ---> False

We get:
not True or True and False

Where not has the highest precedence:
not True ---> False

We get:
False or True and False

Where and has the highest operation precedence:
True and False ---> False

We get:
False or False ---> False

You can use braces to clarify your doubts, they would make the single conditions a bit better readable and understandable. Then you'll see, that the conditions for // edit see other post.

Sorry, didn't read it accurate - first branch is not evaluated as true due to that "and 7==8".
