The built-in number objects in Python supports integers, floating point numbers and complex numbers.

Numeric literals can belong to 3 different numerical types Integer, Float and Complex.

In python, Logical operators are used to perform logical operations on the given relational expressions. There are three logical operators they are and or not.

A Relational operator is also called as Comparative operator which checks the relationship between two operands. If the relation is true, it returns True otherwise it returns False.

Comma (,) is used as a separator in print () to print more than one item.

Syntax:
print ("string to be displayed as output" )
print (variable)
print ("String to be displayed as output", variable)
print ("String1", variable, "String 2", variable, "String 3" .....)

(i) The input () is usedto display the result of the program after execution.
(ii) Reason: The input () function helps to enter data at run time buy the user not to display the output.

(i) The following command can be used t invoke Python IDLE from Window OS.
(ii) Start ⟶ All Programs ⟶ Python 3.x ⟶ IDL (Python 3.x)
(or)
(iii) Click python   Icon on the Desktop if available.

In interactive mode Python code can be directly typed and the interpreter displays the result (s) immediately. The interactive mode can also be used as a simple calculator.

Python shell can be used in two ways, viz. Interactive mode and Script mode.

An Exponent data contains decimal digit part, decimal point, exponent part followed by one or more digits.

Literal is a raw data given in a variable or constant. In Python, there are various types of literals.
1) Numeric Literals:
Numeric Literals consists of digits and are immutable.
2) String Literals:
In Python a string literal is a sequence of characters surrounded by quotes.
3) Boolean Literals:
A Boolean literal can have any of the two values: True or False.

The different operators that can be used in python are
(i) Arithmetic operators
(ii) Relational or Comparative operator
(iii) Logical operators
(iv) Assignment operators
(v) Conditional operator

Python breaks each logical line into a sequence of elementary lexical components known as Tokens. The normal token types are
(i) Identifiers,
(ii) Keywords,
(iii) Operators,
(iv) Delimiters and
(v) Literals.

(i) In Python, programs can be written in two namely Interactive mode and script mode.
(ii) Interactive mode allows us to write codes in Python command prompt (>>>).
(iii) Script mode is used to create and edit python source file.
