Suggested Exercise: Create a combination of a string and numbers out for yourself using IDLE

Worked Example:

Observe the two different ways of defining a function

Notice the output values depending on what is requested

Points of note in the above example:

Any of the two different ways of defining a function can be used depending on a user’s preference because the output will be the same (output for function2 is not shown in the above example to avoid repetitiveness).

The correct output that we want printed is: function1()

The input “print(function 1())” has an output “None”. This is because using the print command on the function invokes the data about the function to be printed - and in our chosen definition there is no return function value.

Printing a function name without the “ () ” will result in the function not being invoked. Therefore, the output will be the object value (eg. <0x02DBA9CO>)
