Some commonly used keywords in Python are given below:


                  False       assert         del            for           in               or             while
                  None        break          elif           from          is               pass           with
                  True        class          else           global        lambda           raise          yield

                  and         continue       except         if            nonlocal         return         async
                  as          def            finally        import        not              try            await


                 CONSTANTS OR LITERALS

                 Constants are fixed values that do not change during the execution of a program. Literals are the
                 type of constant. Literals refer to any number, text and other information that represents a value.
                 Python supports the following literals:



                                              Literals                     Example




                                       String literals           “hello”, ‘12345’

                                       Integer literals          0, 1, 2, -1, -2

                                       Long literals             89675

                                       Floating-point literals   3.14

                                       Complex literals          12j


                                       Boolean literals          True or False

                                       Special literals          None

                                       Unicode literals          u“hello”
                                       List literals             [5,6,7]

                      ▶   Identifiers refer to variables, functions and list.
                      ▶  A token is the smallest element of a Python program that is meaningful to the interpreter.



                 OPERATORS

                 Operators are special symbols that are used to perform specific operation on operands and give
                 a meaningful result. Operands are the data involved in the mathematical operation, and may be
                 stored in variables and constants.
