              -------------------------------------------------------------Interactive shell (Console script)Periodic provides an originally named console script called ‘periodic’.It’s usage for now is limited to periodic table reference.In the future, it will be able to do with elements!This interactive shell may also be invoked from the python interpreter:>>> import periodic
>>> periodic.interactive_shell()Or from the command line:$ periodicEnter any of the following periodic values of the element you are looking for:
        ['atomic', 'symbol', 'name', 'mass']

Use ^C or type 'exit' to exit.
