• Calculator (cell phone calculator okay)
• The table Builtin Methods

Definitions:

Be Able To:

1. Construct a variable trace and predict the output for a Python script.
2. Write a Python script that performs a calculation.
3. Use the str split method to extract the fields from a line.
4. Use variable interpolation in an f-string for output, for example
   

   print(f"{name1} owes {name2} ${round(amt, 2)}")
   

5. Use the rand.randrange method to produce random numbers according to specifications.
6. Write a Python script using sequential processing to solve a problem.
7. Draw the variable trace table and predict the output of a user-defined class.
8. Identify these items in a user-defined class and a script that calls it:
       Class Name, Instance Variable, Instance Method, Public Member, Private Member, Dunder Method, Constructor, Local Variable, Standalone Method, Parameter, Argument
9. Find and correct errors in Python source code.
10. Convert a Python script to a standalone method.
