Section 7.2 Use Library-WE1-P1

Subgoals for using libraries:.

Import module or function (if needed)
1. With alias (optional)
Determine whether parameters are appropriate for function
1. Number of parameters passed must match function documentation
2. Type of parameters passes must match function documentation
Determine what the function will return (i.e., data type), print, and/or change state of arguments and where it will be stored (nowhere, somewhere)
Evaluate expression as necessary
