Non Boolean logical operators

For Non-boolean types :

x=10

y=20

print(x and y)#x is non zero (True), which returns 2nd arg: y(20)

print(x or y)#x is non zero(True), which returns 1st         #    arg: x(10)

print(not x)

"""output

20

10

False

"""

x=1 #non zero: True

y=2#True

z=3#True

print(x and y)# print(True and 2): 2

print(x<y and y<z) #print(1<2 (True) and 2<3(True):True

if(x<y and y<z):  #1<2(True) and 2<3(True):True

    print("Hyd")

else:

    print("Vij")

"""output

2

True

Hyd

In the above statement, compound condition x<y and y<z, this is a combination of two conditions, when ‘and’ is used, the total condition will become ‘True’, if both the conditions are ‘True’ result is also ‘True’, since both the conditions are True, we will get “Hyd” as output.

Note2: 

x=1,y=2,z=3

Here x>y i.e 1>2 (False) but y<z i.e 2<3(True) when using ‘or’ operator if anyone condition is True, it will take the total compound conditions as True.

0 means False, Non-zero means True

Lets take x=1 and y=2

Operator	Example	Meaning	Output
and	X and y	If x is ‘false’, it returns x, otherwise, it returns y	1 and 2= 2
Or	X or y	If x is false, it returns y, otherwise, it returns x	1 or 2= 1
Not	not x	If x is false, it returns True, otherwise False	Not True=False

Expected output: by using logical operators and,or not

200

100

False

x=100

y=200

print(x and y)

print(x or y)

print(not x)

Example4:

10 and 20 result 20

0 and 20 result 0

If first argument is zero then result is zero otherwise result is non-zero

Note: empty string is treated as False.

#empty string is treated as 'False'

print("ravi" and "rajendra") #rajendra

print("" and "Sitha") #false so returns 1^st argu:  #empty string

print("kiran" and "")#True and false i.e empty

print("" or "rajesh) #1^st is false so returns 2nd  i.e #rajesh

print("Hyd" or "") #1^st True so returns 1^st “Hyd

print(not "") # not False i.e True

print(not "Vij") #not True i.e False

output:

rajendra

rajesh

Hyd

True

False

Logical Boolean operators:

Let's take a=True, b=False

Opearators	Example	Meaning	Output
And	a and b	If both a and b are True, then it returns True	False
Or	a or b	If either a or b is True, then it returns True, else false	True
Not	not x	If x is True, it returns False	False

Example program:

a=True

b=False

print(a and a)#True

print(a and b)#False

print(b and b)#False

print(a or a)#True

print(a or b)#True

print(b or b)#False

print(not a)#False

print(not b)#True
