Python Literals

Python Literals

Literal is raw data that is mainly assigned to a variable or constant.

In Python, there are many types of literals that are as follows:

Numeric Literals:

Numeric Literals are unchangeable (immutable), meaning the value once assigned cannot be changed.

Numeric literals belong to 4 different numerical types:

  • Numeric Literals - Numeric Literals: Numeric Literals are unchangeable which means the value once assigned cannot be changed. Numeric literals belong to 3 different numerical types: Integer, Float, and Complex.
  • Long - Unlimited size followed by “L .“
  • Float - Real Numbers with or without decimals.
  • Complex - In the form of a + bi, where bi = imaginary part and a = real part.

NOTE:- Whenever you print the variables, all the literals are converted into decimal values.

String literals:

A string literal is a sequence of characters that are surrounded by quotes. We can use single and double or triple quotes to create a String.

The string is of two types:-

  • Single-line string - A line that terminates in a single line is called a single-line string.
  • Multi-line string - Texts which are written in multiple lines are called Multi-line string.
We can create a Multi-line string in two ways:-    
                    
By adding a slash “ \ ” at the end of the line.
    E.g., var1 = “Hello \
                          World1”
    By using triple quotation “ ‘“ “ marks
    E.g., var2 = ‘“ Hello 
                           World2 ’”

String literals:

Boolean literals:

This type of literals can have only two types of values:

  • True
  • False

Special literals:

Python contains one type of particular literal that is None

. We have been using it to specify that the field has not been created and used to end the list in Python.

Literal Collection

In Python, there are four literal collections:-

  • List literal
    • Their elements may have different data types as the list accepts different data types for a single variable.
    • The list can be modified.
    • Items in the list are separated by comma (,).
    • The list is enclosed with a square bracket, [ ]
  • Tuple literal
    • Their elements may have different data types as the tuple accepts different data types for a single variable.
    • The tuples can not be modified.
    • Items in the tuples are separated by comma (,).
    • The tuple is enclosed with parentheses, ()
  • ⦁ Dict literal
    • Python dictionary uses key-value pair to store the data inside its curly brackets, {}.
    • The pair of the dictionary are separated by comma (,).
    • Python Dict uses a colon (:) to separate the key and the value pair.
  • Set literal
    • Python contains the unordered dataset collection.
    • Set uses curly brackets to enclose its data, {}.
    • Elements in the set are separated by comma (,).

Example No.1:

x = 24 y = 24.3 z = 2+3j print(x, y, z)

OUTPUT:

24 24.3 (2+3j)

Example No.2:

s = 'Knowledge2life' t = "Knowledge2life" m = '''Knowledge2life''' print(s) print(t) print(m)

OUTPUT:

Knowledge2life
Knowledge2life
Knowledge2life
