Zmienne w Pythonie<\/h4>\n\n\n\n

Zmienne to „pude\u0142ka” w kt\u00f3rych przechowujemy dane. W Pythonie nie musisz deklarowa\u0107 typu zmiennej – Python sam go rozpoznaje.<\/p>\n\n\n\n

Podstawowe typy danych:<\/h4>\n\n\n\n
    \n
  • str<\/strong> – tekst (string)<\/li>\n\n\n\n
  • int<\/strong> – liczby ca\u0142kowite<\/li>\n\n\n\n
  • float<\/strong> – liczby zmiennoprzecinkowe<\/li>\n\n\n\n
  • bool<\/strong> – warto\u015bci logiczne (True\/False)<\/li>\n<\/ul>\n\n\n\n

    Tworzenie zmiennych:<\/h4>\n\n\n\n

    W Pythonie tworzysz zmienn\u0105 po prostu przypisuj\u0105c jej warto\u015b\u0107:<\/p>\n\n\n\n
