Basic Python course

From scratch: everything you need to write your first programs. In DMarlon Studio, Python powers desktop apps (tkinter), Flask websites and the console: design the window and the studio writes the Python code.

Start
  1. 1Hello, worldYour first Python program: print() writes text and results to the console. Run it with one click in DMarlon Studio.Lesson 1
  2. 2Variables and typesStore data in Python variables and find out their types (str, float, int and bool) with type(), using a small shop as the example.Lesson 2
  3. 3Numbers and arithmeticDo maths in Python: whole division with //, remainders with %, powers with ** and rounding with round(), while sharing out some pizzas.Lesson 3
  4. 4Strings and f-stringsWork with text in Python: join and repeat strings, count characters with len(), read positions and format values with f-strings.Lesson 4
  5. 5Reading from the keyboardAsk the user for data with input() in Python and convert it into numbers with int() and float() so you can do maths with it.Lesson 5
  6. 6Deciding with if, elif and elseMake your Python program take decisions with if, elif and else: what to wear for the weather and whether delivery is free.Lesson 6
  7. 7Comparisons and logicCompare values in Python with ==, !=, < and >=, and combine conditions with and, or and not to decide who rides the roller coaster.Lesson 7
  8. 8Repeating with whileRepeat code in Python with while as long as a condition holds: save up for a bike week by week and run a countdown.Lesson 8
  9. 9For loops and range()Loop over letters and numbers with for and range() in Python: a times table, Olympic years, a running total and break to stop early.Lesson 9
  10. 10ListsKeep several values in a Python list: read them by position, change them, loop over them with for and add them up with sum(), min() and max().Lesson 10
  11. 11Working with listsAdd, remove and sort the items of a Python list with append, insert, remove, pop and sort, and take parts of it with slicing [a:b].Lesson 11
  12. 12Tuples and unpackingUse Python tuples for data that does not change, and unpack them into several variables at once, even inside a for loop.Lesson 12
  13. 13DictionariesStore key-value pairs in a Python dictionary: a greengrocer's stock with get(), del, items(), keys() and values().Lesson 13
  14. 14SetsRemove duplicates with Python sets and compare groups with intersection, union and difference: who belongs to each school club.Lesson 14
  15. 15FunctionsCreate your own Python functions with def, pass them data and send results back with return, while printing a café's receipts.Lesson 15
  16. 16Parameters, defaults and returnGive default values to the parameters of your Python functions, call them by name and send back several results with return.Lesson 16
  17. 17String methodsClean up and transform text in Python with strip, split, join, lower, upper, replace, find and count, tidying a list of ingredients.Lesson 17
  18. 18Errors with try and exceptCatch the errors in your Python program with try and except so it keeps going: bad numbers, division by zero and missing keys.Lesson 18
  19. 19Writing and reading filesSave data to a text file with Python and read it back with open(), write() and read(): the high scores of a game.Lesson 19
  20. 20Project: grade reportA project that brings the basic Python course together: it reads marks from a file, skips bad data and prints a report with averages and grades.Lesson 20
