    Operator Precedence
                     An arithmetic expression without parentheses will be evaluated from left to right using the rule of

                     precedence of operators.

                     Write a program to use operators in Python.

                     PUNCTUATORS

                     Punctuators are also called separators as they are used to separate lines of codes, variables, etc.
                     The following characters are used as punctuators in Python: ` # \ () [] {} @ , : . ‘ =

                       Brackets []   indicate list.

                       Parentheses ()   indicate tuples, function calls, function parameters for grouping expressions
                       etc.
                       Comma (,)   is used as a separator in a function argument list or variable declaration.

                       Colon (:)   indicates a labelled statement or conditional operator symbol.

                       Equal sign (=)   is used to initialise the value of variable.

                                                                                        Tokens and Data Types in Python  143
