Q1: Write a program that generates a random number 1 to 1000 and prints that value. Then it evaluates the square root of that number and prints that value.
Section 8.3 Assessment: APIs
Subgoals for using libraries:.
-
Import module or function (if needed)
- With alias (optional)
-
Determine whether parameters are appropriate for function
- Number of parameters passed must match function documentation
- 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
