notice that the division operator evaluates to float valueas in evaluating to math operations with float values also evaluate to float valuesas in evaluating to syntax errors if you enter into the interactive shellyou'll get an error message syntaxerrorinvalid syntax this error happened because isn' an expression expressions have values connected by operators but the operator expects value after the sign an error message appears when this value is missing syntaxerror means python doesn' understand the instruction because you typed it incorrectly lot of computer programming isn' just telling the computer what to dobut also knowing how to tell it don' worry about making mistakes though errors don' damage your computer just retype the instruction correctly into the interactive shell at the next prompt storing values in variables you can save the value an expression evaluates to so you can use it later by storing them in variables think of variables like box that can hold value an assignment statement instruction will store value inside variable type the name for the variablefollowed by the sign (called the assignment operator)and then the value to store in the variable for exampleenter spam into the interactive shellspam the spam variable' box will have the value stored in itas shown in figure - the name "spamis the label on the box (so python can tell variables apartand the value is written on small note inside the box when you press enter you won' see anything in response in pythonthe instruction executed was successful if no error message appears the prompt will appear so you can type in the next instruction
