                        •  A computer language  is the means by which instructions and data  are transmitted to the
                        computer.

                        •  Compilers and interpreters are types of software that convert the source program into machine
                        language before executing it.
                        •  Interactive Mode is a command line shell which gives immediate result for each command.
                        •  IDLE stands for Integrated Development and Learning Environment.
                        •  The input() function takes the user’s input while a program executes.
                        •  The print() function prints or sends the output to the standard output device, which is usually
                        a monitor.
                        •  Variables are memory reference points where we store values which can be accessed or changed
                        later.
                        •  A data type specifies the type of value a variable can contains.
                        •  Comments enable us to understand the way a program works.
                        •  Operators can be defined as special symbols which perform arithmetic and logical computation.
                        •  Arithmetic operators perform arithmetic operations between two operands.
                        •  The assignment operators are used to assign the value of the right expression to the left operand.
                        •  Relational operators are used to compare the value of the two operands and returns True or
                        False accordingly.
                        •  Precedence of operators determines the order in which the operators are executed.
