Lesson 2/2~48 min

Programming challenges

Decisions in a program: a grade, a calculator, sorting three numbers and a parking fee.

After this lesson you'll be able to:

  • Write a whole program from a specification and check it with tests
  • Print exactly what the task asks for - the tests compare the output line by line (trailing spaces do not matter). Write any prompt you like in input("…"); the tests ignore it.
  • The last task is an optional bonus if you want more.
