                 Logical Operators


                 They are used to combine multiple conditions and evaluate them. They return a Boolean value
                 ‘True’ or ‘False’ as result.
                             Operator                                    Description

                              & (AND)          Returns ‘true’ value if all the given conditions are true.

                               | (OR)          Returns ‘true’ value if any one of the given conditions is true.

                     COMMENTS IN PYTHON

                 Comments are the text written inside the code for better understanding of the code. A hash
                 character (#) is written at the beginning of the comment. Comments are not a part of the code
                 and are ignored by the Python interpreter.
                 For example, #Program on simple calculator
                 This line will not be read by the Python interpreter but it is giving information about the program
                 to the reader.
                     THE INPUT( ) STATEMENT

                 This statement is used to take input from the user during the execution of the program. The
                 input statement acts as a message communicator between the user and the computer.

                 The general syntax is :
                 Syntax     input  (“prompt”), here prompt is a message for the user related to the code.
                 Example  X = input ("What is your name?" )
                 In this example, the input statement will use the prompt “What is your name?” to get the input
                 from user and assign it to the variable X.

                 The value taken from the input statement is a string value. To convert this value into an integer
                 or float for further calculation, use the following functions:
                  Function                   Description                                   Example

                  Int ( )    The int ( ) function converts a float or      int (x) converts variable x into an
                             string variable into int data type            integer
                  float ( )  The float ( ) function converts a string or  float (x) converts variable X into a
                             int variable into a float data type           floating point number.

                     THE PRINT( ) STATEMENT

                 The print ( ) statement is used to print the output of a program on the screen. The general syntax is :
                 Syntax     print (“message” , variable _ name)

                 Example  print ("Area of the square is", area)
