 Metoda 1: Po\u0142\u0105cz poszczeg\u00f3lne tabele<\/strong><\/span><\/h3>\n
 Poni\u017cszy kod pokazuje, jak utworzy\u0107 tablic\u0119 tablic, po prostu \u0142\u0105cz\u0105c poszczeg\u00f3lne tablice:<\/span><\/p>\n

 Metoda 2: bezpo\u015brednio utw\u00f3rz tablic\u0119 tabel<\/strong><\/span><\/h3>\n
 Poni\u017cszy kod pokazuje, jak bezpo\u015brednio utworzy\u0107 tablic\u0119 tablic:<\/span><\/p>\n
 import<\/span> numpy as<\/span> np<\/span>\n\n#create array of arrays\n<\/span>all_arrays = np. array<\/span> ([[10, 20, 30, 40, 50],\n                       [60, 70, 80, 90, 100],\n                       [110, 120, 130, 140, 150]])\n\n#view array of arrays<\/span>\nprint<\/span> (all_arrays)\n\n[[ 10 20 30 40 50]\n [60 70 80 90 100]\n [110 120 130 140 150]]\n<\/span><\/span><\/strong><\/pre>\n
 Nale\u017cy zauwa\u017cy\u0107, \u017ce ta tablica tablic odpowiada tablicy utworzonej przy u\u017cyciu poprzedniej metody.<\/span><\/p>\n
 Jak uzyska\u0107 dost\u0119p do element\u00f3w tablicy tablic<\/strong><\/span><\/h3>\n
 Mo\u017cesz u\u017cy\u0107 funkcji kszta\u0142tu<\/strong> , aby pobra\u0107 wymiary tablicy tablic:<\/span><\/p>\n
 print<\/span> ( all_arrays.shape<\/span> )<\/span>\n\n(3, 5)\n<\/span><\/span><\/strong><\/pre>\n
 To m\u00f3wi nam, \u017ce w tabeli tabel znajduj\u0105 si\u0119 trzy wiersze i pi\u0119\u0107 kolumn.<\/span><\/p>\n
 Mo\u017cesz u\u017cy\u0107 funkcji size<\/strong> , aby zobaczy\u0107, ile ca\u0142kowitych warto\u015bci znajduje si\u0119 w tablicy tablic:<\/span><\/p>\n
 print<\/span> ( all_arrays.size<\/span> )<\/span>\n\n15<\/span><\/span><\/strong><\/pre>\n
 To m\u00f3wi nam, \u017ce w tablicy tablicowej znajduje si\u0119 \u0142\u0105cznie 15 warto\u015bci.<\/span><\/p>\n
 Za pomoc\u0105 nawias\u00f3w<\/strong> mo\u017cna uzyska\u0107 dost\u0119p do element\u00f3w znajduj\u0105cych si\u0119 w okre\u015blonych pozycjach tablicy tabel.<\/span><\/p>\n
 Na przyk\u0142ad mo\u017cesz u\u017cy\u0107 nast\u0119puj\u0105cej sk\u0142adni, aby pobra\u0107 warto\u015b\u0107 pierwszej tablicy znajduj\u0105cej si\u0119 na pozycji indeksu 3:<\/span><\/p>\n
 print<\/span> (all_arrays[0, 3])<\/span>\n\n40<\/span><\/span><\/strong><\/pre>\n
