Boolean Literals :

Boolean Literal has any of the two values True or False.

True is treated as 1 and False is treated as 0.

Code:

b1 = (1 == True)
b2 = (0 == False)
x = True + 1
y = False + 3
print("b1 is: ", b1) #print value of b1
print("b2 is: ", b2) #print value of b2
print("x is: ", x)   #print value of x
print("y is: ", y)   #print value of y

Output:

b1 is: True
b2 is: True
x is: 2
y is: 3

Since True represents 1 and False represents 0, b1 and b2 are True. Similarly for x and y.

Special Literal :

Python provides a special Literal called None. It is used for specifying that the field has not been created.

Code:

skills = ['coding', 'blogging', 'freelancing']

def checkskill(skill):
    if skill in skills:
        print('yes')  #check with strings in array if it matches then return yes else return no
    else:
        print(None)

checkskill('coding')
checkskill('painting')

The function chekskill() checks whether the provided skill is present in skills or not. If yes prints yes, else prints None.

Literal Collections :

In python, there are 4 types of literal Collections. They are

List Literals
Tuple Literals
Set Literals
Dictionary Literals

Code:

languages = ['java', 'python', 'c++']
numbers = (1, 2, 3, 4, 5, 6, 7, 8, 9)
maang = {'m': 'Meta',
         'a': 'Apple',
         'a':  'Amazon',
         'n': 'Netflix',
         'g': 'Google'}
vowels = {'a', 'e', 'i', 'o', 'u'}

print(languages)  #print langauges from langauges array
print(numbers) #print numbers from numbers array
print(maang)  #print maang from maang array
print(vowels)  #print vowels from vowels array

Here the languages are the List Literal, numbers are tuple Literal, maang is Dictionary Literal, and vowels are Set Literal.
To know more about the Literal Collections refer to Python Data Types.

Difference between a Variable, Constant and Literal

Variables	Constants	Literals
Variable is the name of the memory location where the data is stored.	A constant is a variable whose value cannot be changed	Literals are raw values or data that are stored in a variable or constant
Variables are mutable i.e their values can be changed or updated
