PCEP Operator Precedence and Binding 2

Question 1

What is the result of `2 + 3 * 4 - 1`?

Accepted Answer

13

Answer

Multiplication is evaluated first (3*4=12), then left-to-right addition and subtraction: 2+12-1=13.

Question 2

Which operator has the highest precedence in Python?

Accepted Answer

**

Answer

The exponentiation operator `**` has the highest precedence among arithmetic operators in Python.

Question 3

What does `True or False and False` evaluate to?

Accepted Answer

True

Answer

`and` has higher precedence than `or`, so `False and False` is evaluated first (False), then `True or False` equals True.

Question 4

What is the result of `10 // 3 + 1`?

Accepted Answer

4

Answer

Floor division `//` has the same precedence as `*` and `/`, so `10//3=3`, then `3+1=4`.

Question 5

How does Python evaluate `not True and False`?

Accepted Answer

False

Answer

`not` has higher precedence than `and`, so `not True` evaluates to False first, then `False and False` equals False.
