Using expressions A combination of values, variables and operators is called an expression. An expression typed in the shell gets evaluated, and the answer is displayed. However, in a script, an expression doesn't do anything on its own. ...
Optional: You can make your program more beautiful and compact, using functional programming style, by storing the procedures associated with each operator in the subclass. The Python module operator provides definitions of the procedures for the arithmetic operators. Here is an ...
