## Boolean Values

It's common in programming to need to know whether an expression is `True` or `False`.

In Python, you can evaluate a certain expression and receive one of two results: `True` or `False`.

Example 1 :- Compare two values by evaluating the expression and by returning the boolean answer to Python :

``````print(10 > 9)
print(10 == 9)
print(10 < 9)``````

Output :-

True
False
False

Python will return `True` or `False` if you have a condition in a statement `if` :

Example 2 :- Depending on whether the condition is `True` or `False`, print the following message :

``````a = 200
b = 33
if b > a:
print("b is greater than a")
else:
print("b is not greater than a")``````

Output :-

b is not greater than a

## Evaluate Values and Variables

You can evaluate any value by using the `bool()` function and return `True` or `False`.

Example 1 :- Evaluate a string and a number :

``````print(bool("Hello"))
print(bool(15))``````

Output :-

True
True

Example 2 :- Evaluate two variables :

``````x = "Hello"
y = 15
print(bool(x))
print(bool(y))``````

Output :-

True
True

## Most Values are True

If you have some sort of content, almost every value is evaluated to `True`.

Every string, except empty strings, is `True`.

Any number is `True`, except `0`.

Except for empty lists, tuples, sets and dictionaries, all are `True`.

Example :- The following will return True :

``````print(bool("abc"))
print(bool(123))
print(bool(["apple", "cherry", "banana"]))``````

Output :-

True
True
True

## Some Values are False

In fact, with the exclusion of empty values (for instance `()`, `[]`, `{}`, `""` number 0 and value None), False does not value many values. And `False` value is of course `False` value.

Example 1 :- The following will return False :

``````print(bool(False))
print(bool(None))
print(bool(0))
print(bool(""))
print(bool(()))
print(bool([]))
print(bool({}))``````

Output :-

False
False
False
False
False
False
False

## Functions can Return a Boolean

The functions you can create can return a boolean value :

Example 1 :- Print the answer of a function :

``````def myFunction() :
return True
print(myFunction())``````

Output :-

True

You can run code based on a function's Boolean result :

Python has also many incorporated functions, such as the `isinstance()` function, that can be employed to determine if an object is of a certain type of data :

Example 2 :- Check if an object is an integer or not :

``````x = 200
print(isinstance(x, int))``````

Output :-

True
