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.

(iv) name = "Kumar"
Reason: No function character allowed within identifiers.

(i) An identifies must start with an alphabet.
(ii) No punctuation characters are allowed.
(iii) Only underscore (-) allowed.

Variable = input ("prompt string")
Where, prompt string in the syntax is a statement or message to the user, to know what input can be given.

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.

The input () function helps to enter data at run time by the user and the output function print () is used to display the result of the program on the screen after execution.

The prompt >>> indicates that Interpreter is ready to accept instructions. Therefore, the prompt on screen mean IDLE is working in interactive mode.

(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.

The version 3. x of Python IDLE (Integrated Development Learning Environment) is used to develop and run Python code.
