Logical Operators practice (Interactive mode)

Q. Logical Operators' practice (Interactive mode)

x = 29.0, y = 13, z = 2, p = 0.5, q = 12.79, i = 13, j = 29.0, k = y – 11, a = ''(empty string), b = '', c = 'great', d = 'Great', e = 'GREAT', f = 'Great', g = 'GREAT', h = ' great', l = (3 + 4.5j), m = (3 + 4.5j)

Answer :-

 

 
	 
S. No.
 
	 
Expression
 
	 
Result
 
	 
Reason
 
 
 
	 
1
 
	 
x > y and y > z
 
	 
True
 
	 
If both are true then and operator return True.
 
 
 
	 
2
 
	 
x > y or y > z
 
	 
True
 
	 
If both are true then or operator return True.
 
 
 
	 
3
 
	 
not x > y
 
	 
False
 
	 
not operator return opposite of answer.
 
 
 
	 
4
 
	 
not x > y or y > z
 
	 
True
 
	 
If one of them is True then or operator return True
 
 
 
	 
5
 
	 
not (x > y or y > z)
 
	 
False
 
	 
not operator return opposite of answer.
 
 
 
	 
6
 
	 
x - y * 2 > y * 2 or y * p > y
 
	 
False
 
	 
We should know the precedence order of operators.
 
 
 
	 
7
 
	 
x - y * 2 > y * 2 and y * p > y
 
	 
False
 
	 
We should know the precedence order of operators.
 
 
 
	 
8
 
	 
not x - y * 2 > y *2 and y * p > y
 
	 
False
 
	 
If both are not true then and operator return False.
 
 
 
	 
9
 
	 
not (x - y * 2 > y *2 and y * p > y)
 
	 
True
 
	 
not operator return opposite of answer.
 
 
 
	 
10
 
	 
x - y * 2 > y * 2 and not y * p > y
 
	 
False
 
	 
We should know the precedence order of operators.
 
 
 
	 
11
 
	 
x - y * 2 > y * 2 or not y * p > y
 
	 
True
 
	 
If one of them is True then or operator return True
 
 
 
	 
12
 
	 
x > y > z
 
	 
True
 
	 
If all condition is True then it will return True.
 
 
 
	 
13
 
	 
i < j > k
 
	 
True
 
	 
If all condition is True then it will return True.

y & z
 
	 
 
	 
 
 
 
	 
15
 
	 
y | z
 
	 
 
	 
 
 
 
	 
16
 
	 
y ^ z
