+# Laboratoria 3
+
+## Zadania
+
+**ćwiczenie 0**
+Sklonuj repozytorium ``https://github.com/realpython/python-scripts``, które różne, przydatne skrypty. Przejrzyj je i zobacz na ile jesteś w stanie zrozumieć co i jak robią. Uruchom kilka z nich, np. ``27_send_sms.py``.
+
+**ćwiczenie 1**
+Każdy obiekt w Pythonie na wbudowaną funkcję ``id()``, która zwraca liczbę, która jest unikatowa i stała dla obiektu. Pozwala ona w prosty sposób sprawdzić, który obiekt jest *mutable*a, który *immutable*: jeżeli po wykonaniu operacji, zwracana liczba jest stała, to oznacza, że obiekt jest *mutable*. Sprawdź zachowanie funkcji na obiektach typy:
+ * lista,
+ * napis (string),
+ * liczba zmiennoprzecinkowa.
+
+**ćwiczenie 2**
+Napisz generator, który będzie zwracać ``n`` kolejnych liczb ciągu Fibonacciego (``F(0)=1, F(1)=1, FN=F(N-1) + F(N-2)``).
+
+**ćwiczenie 3**
+Strona ``https://api.fixer.io/latest`` udostępnia kursy różnych walut w stosunku do euro. Napisz skrypt, który:
+ * pobierze zawartość JSONa. Wykorzystaj bibliotekę ``requests`` (http://docs.python-requests.org/en/master/).
+ * korzystając z biblioteki ``json`` przekształć go do obiketu typu JSON.
+ * Wyświetl wartość kursu EUR do PLN.
+
+**ćwiczenie 4**
+Zainstaluj bibliotekę ``weather-api`` (https://pypi.python.org/pypi/weather-api). Korzystając z niej:
+ * Wypisz informacje o aktualnej pogodzie.
+ * Napisz funkcję, która zamieni stopnie ``F`` na ``C``.
+ * Korzystając z prognozy, znajdź dzień, w którym będzie najzimniej. Wypisz nazwę tygodnia (w języku polskim) i temperaturę w C.
+
+**ćwiczenie 5**
+Katalog scores zawiera 64 pliki tekstowe, które posiadają informacje o wysokości miary ``BLEU`` na różnych etapach trenowania modelu. Nazwa każdego pliku na postać  ``model.iterXXXXXXX.npz.bleu``, gdzie ``XXXXXXX``, to liczba iteracji.Zawartość każdego pliku jest podobna i ma następującą formę: *BLEU = YY.YY, 44.4/18.5/9.3/5.0 (BP=1.000, ratio=1.072, hyp_len=45976, ref_len=42903)*, gdzie ``YY.YY`` to wartość miary ``BLEU``. Znajdź plik, który zawiera najwyższą wartość miary ``BLEU``.
+ * Wykorzystaj bibliotekę ``glob`` (https://docs.python.org/2/library/glob.html)
+ * Wyświetl tylko pełną nazwe pliku (wraz z ścieżką).

+**ćwiczenie 1**
+Napisz funckję ``is_numeric``, która sprawdzi, czy każdy element z przekazanej listy jest typu int lub float. Wykorzystaj funcję ``isinstance()`` (https://docs.python.org/2/library/functions.html#isinstance).
+
+**ćwiczenie 2**
+Napisz prostą hierarchię klas:
+ * Klasa bazowa ``Employee``, która będzie zawierać informacje o imieniu i nazwisku pracownika. Ponadto każdy pracownik otrzyma numer ``id``, który będzie unikatowy. Wykorzystaj do tego atrybut statyczny. Napisz metodę ``get_id``, która zwraca identyfikator pracownika.
+ * Klasy pochodna:  ``Recruiter``, która ma dodatkową mtodę ``recruit``, która jako parament przyjmuje obiekt ``Employee`` i zapisuje jego ``id`` w liście ``self.recruited``.
+ * Klasa pochodna ``Programmer``. Klasa ``Programmer`` ma przyjąć w konstruktorze podstawowe informacje (imię i nazwisko) oraz obiekt rekturera. Ponadto stwórz  atrybut ``recruiter``, który będzie przechowywać ``id`` rekrutera.
+
+**ćwiczenie 3 (zadanie domowe) **
+Stwórz klasę ``Point``, która będzie reprezentować punkt w przestrzeni wielowymiarowej:
+ * Konstruktor ma przyjąc tylko 1 parametr: listę współrzednych. Wykorzystaj funkcję z pierwszego zadania, żeby sprawdzić, czy lista zawiera wyłącznie liczby.
+ * Napisz metodę add, która dida dwa punkty po współrzędnych i zwróci obiekt typu ``Punkt``. Zaimplementuj własny wyjątek ``DimensionError``, który zostaje wyrzucony, jeżeli dodawany punkt ma inny wymiar.
+ * Napisz metodę ``to\_string``, która zwróci łancuch znakowy, który w czytelny sposób przedstawi punkt.
+ * Napisz metodę __len__, która zwróci liczbę współrzędnych punktu. Zobacz, czy możesz teraz wywołać funkcję len na obiekcie typy punkt.
+ * Napisz metodę __str__, która bedzie działać dokładnie tak samo jak metoda ``to_string``. Wyświetl obiekt typy Point korzystając z funkcji print.
