Solutions
Functions may only work for certain (combinations of) arguments.
Functions may have default values for some arguments.
Functions attached to objects are called methods
Use the built-in function
help
to get help for a function.
The Jupyter Notebook has two ways to get help.
Python reports a syntax error when it can’t understand the source of a program.
Python reports a runtime error when something goes wrong while a program is executing.
What Happens When

The pythonic example
Use variables to store values.
Use
print
to display values.
Variables must be created before they are used.
Variables Persist Between Cells
Variables can be used in calculations.
