Lesson 2/2~48 min

Programming challenges

Lists of numbers: sums, walking backwards, finding the minimum and shifting items.

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.
