What is Boolean Data Type in Python | EP-29 Boolean Datatype in Python | Python Booleans| Data Types
2Python Boolean
"""Boolean type is one of the built-in data types provided by Python, which represents
one of the two values i.e. True or False. Generally, it is used to represent the truth
values of the expressions. The output class ‘bool’ indicates the variable is a boolean
data type. """
a=int(input("enter the number"))
if a==1:
print(True)
else:
print(False)
a= True
print(type(a))
b= False
print(type(b))
syntax: bool([x])
return false as x is not equal to y
x=5
y=10
print(bool(x==y))
return false as x is none
x=None
print(bool(x))
return false as x is an empty sequence
x=()
print(bool(x))
return false as x is an empty mapping
x={}
print(bool(x))
return false as x is 0
x=0
print(bool(x),'zero')
return x as true as x is a non empty string
x="cybrosys"
print(bool(x))
Boolean Operators
"""
Boolean Operations in Python are simple arithmetic of True and False values.
These values can be manipulated by the use of boolean operators which include AND, Or,
and NOT. Common boolean operations are
or
and
not
== (equivalent)
!= (not equivalent)"""
Boolean OR Operator
"""
The Boolean or operator returns True if any one of the inputs is True else returns False."""
a=1
b=2
c=4
if a greater than b or b greater than c: 1 greater than 2 or 2 greater than 4 false or false
print(True)
else:
print(False)
Boolean And Operator
"""
The Boolean operator returns False if any one of the inputs is False else returns True."""
a=0
b=2
c=4
if a less than b and b less than c: 0 less than 2 and 2 less than 4
print(True)
else:
print(False)
Python Boolean Not Operator
"""when the value of a is 0, it is considered false, and the code block inside the
if statement is executed, printing the corresponding message."""
a=0
if not a:
print("boolean value of a is false")
Boolean == (equivalent) and != (not equivalent) Operator
"""Both operators are used to compare two results. == (equivalent operator returns True
if two results are equal and != (not equivalent operator returns True if the two
results are not same."""
