Q. What is Boolean?
R. In Computer science or Computer programming language, a Boolean or bool is a Data Type with two possible values: True or False .

In Simple we can say that Booleans represent one of two values: True or False .

# Boolean Values
We often need to know if an expression is True or False.

We can evaluate any expression in Python, and get one of two answers, True or False.
When we compare two values , the expression is evaluated and Python returns the Boolean answer.

When we run a condition in an if statement, Python returns True or False:
#Evaluate Values and Variables
In Python there is bool() function allows us to evaluate any value, and get answer as True or False in return,

For Example:-
print(bool("Hello"))
print(bool(1))

In Python there are Most of values are True--------

• Almost any value is evaluated to True if it has some sort of content.
• Any string is True, except empty string.
• Any Number is True, except 0.
• Any list, tuple, set, and dictionary are True, except empty ones.

Also In Python some values are False
In fact, there are not many values that evaluate to False, except empty values, such as (), [], {}, "", the number 0, and the value None.
And of course the value False evaluates to False.

For Example:-
bool(False)
bool(None)
bool(0)
bool("")
bool(())
bool([])
bool({})

# Functions can Return a Boolean
We can create functions that returns a Boolean Values:-
