Learn Python like a Professional! Take You from 0 to Hero

In this Python lecture, we will learn about the Boolean.

" Boolean values are the two constant objects False and True ".

We can use built-in bool() function or comparison operators to get the boolean result.

Let's look at the Boolean examples-

a = 1

b = 2

print( a < b )

>>True

print(bool( a > b))

>> False

print(bool( a == b))

>> False

We can also use bool() function

print(bool( a != b)) # Returns True when the argument is true, False otherwise

>> True

Check The Type

We have built-in function type() to check the type of object.

type(True)

>> bool

type(false)

>> bool

type(0)

>> int

type('value')

.>> str

Cast Into Boolean

We can use built-in bool() method to cast the object in the boolean type

1.Integer to boolean

bool(1)

>> True

bool(0) # Notice O is casted as false in boolean

>> False

2.String to Boolean

bool('value')

>> True

bool(' ')  # Notice Space is casted as false in boolean

>> False

Boolean to Integer

int(True) # Notice True is casted as 1 in integer type

>> 1

int(False) # Notice False is casted as 0 in integer type

>> 0

Also, try to cast boolean to string

EDITS ARE WELCOMED!!

In the next Blog, we will discuss Q&A first.
