Answer :-

Note :- In python ‘0’ and ‘’ (empty string) treated as False and all other number (e.g. 1, 1.3652, -9.25, 6, 0.0001 ) and “ABC…” treated as True.

Expression
 
	 
Result
 
	 
Reason
 
 
 
	 
1
 
	 
r and p
 
	 
0
 
	 
In and operator if one of them is zero then it will return zero.
 
 
 
	 
2
 
	 
p and r
 
	 
0
 
	 
In and operator if one of them is zero then it will return zero.
 
 
 
	 
3
 
	 
p and q
 
	 
12.79
 
	 
If both value is non zero the and operator return last value.
 
 
 
	 
4
 
	 
q and p
 
	 
0.5
 
	 
If both value is non zero the and operator return last value.
 
 
 
	 
5
 
	 
r or p
 
	 
0.5
 
	 
In or operator if it is True then it returns non zero value.
 
 
 
	 
6
 
	 
p or r
 
	 
0.5
 
	 
In or operator if it is True then it returns non zero value.
 
 
 
	 
7
 
	 
p or z
 
	 
0.5
 
	 
In or operator if both value is true then it will return first value.
 
 
 
	 
8
 
	 
z or p
 
	 
2
 
	 
In or operator if both value is true then it will return first value.
 
 
 
	 
9
 
	 
p or q
 
	 
0.5
 
	 
In or operator if both value is true then it will return first value.
 
 
 
	 
10
 
	 
q or p
 
	 
12.79
 
	 
In or operator if both value is true then it will return first value.
 
 
 
	 
11
 
	 
not q or p
 
	 
0.5
 
	 
Here first True is converted into False due to not operator so or operator return second True
 
 
 
	 
12
 
	 
a and not q
 
	 
''
 
	 
Here empty operator treated as false
 
 
 
	 
13
 
	 
s and x
 
	 
0.0
 
	 
Here 0.0 treated as False
 
 
 
	 
14
 
	 
not s and x
 
	 
29.0
 
	 
In and operator if both value is true then it will return second value.
 
 
 
	 
15
 
	 
z or s
 
	 
2
 
	 
In or operator if both value is true then it will return first value.
 
 
 
	 
16
 
	 
s or z
 
	 
2
 
	 
In or operator if both value is true then it will return True value from both of them.
 
 
 
	 
17
 
	 
z - 2 or s
 
	 
0.0
 
	 
In or operator if both value is False then it will return second value.
 
 
 
	 
18
 
	 
s or z - 2
 
	 
0
 
	 
In or operator if both value is False then it will return second value.
 
 
 
	 
19
 
	 
z + 2 or s
 
	 
4
 
	 
In or operator if both value is true then it will return first value.
 
 
 
	 
20
 
	 
s or z + 2
 
	 
4
 
	 
In or operator it will return True value from both of them.
