Anda dapat menggunakan metode berikut untuk mengurutkan baris array NumPy berdasarkan nilai kolom:<\/span><\/p>\n

Metode 1: Urutkan berdasarkan nilai kolom dalam urutan menaik<\/strong><\/span><\/p>\n

 x_sorted_asc = x[x[:, 1]. argsort<\/span> ()]\n<\/strong><\/pre>\n
 Metode 2: Urutkan berdasarkan nilai kolom menurun<\/strong><\/span><\/p>\n
 x_sorted_desc = x[x[:, 1]. argsort<\/span> ()[::-1]]<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan masing-masing metode dalam praktik.<\/span><\/p>\n
 Contoh 1: Urutkan array Numpy berdasarkan nilai kolom dalam urutan menaik<\/strong><\/span><\/h3>\n
 Misalkan kita memiliki array NumPy berikut:<\/span><\/p>\n
 import<\/span> numpy as<\/span> np\n\n#create array\n<\/span>x = np. array<\/span> ([14, 12, 8, 10, 5, 7, 11, 9, 2]). reshape<\/span> (3,3)\n\n#view array\n<\/span>print<\/span> (x)\n\n[[14 12 8]\n [10 5 7]\n [11 9 2]]\n<\/span><\/span><\/strong><\/pre>\n
 Kita dapat menggunakan kode berikut untuk mengurutkan baris tabel NumPy dalam urutan menaik berdasarkan nilai pada kolom kedua:<\/span><\/p>\n
 #define new matrix with rows sorted in ascending order by values in second column\n<\/span>x_sorted_asc = x[x[:, 1]. argsort<\/span> ()]\n\n#view sorted matrix\n<\/span>print<\/span> (x_sorted_asc)\n\n[[10 5 7]\n [11 9 2]\n [14 12 8]]<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa baris sekarang diurutkan dalam urutan menaik (terkecil hingga terbesar) berdasarkan nilai di kolom kedua.<\/span><\/p>\n
 Contoh 2:<\/strong><\/span> Urutkan array Numpy berdasarkan nilai kolom menurun<\/strong><\/span><\/h3>\n
 Misalkan kita memiliki array NumPy berikut:<\/span><\/p>\n
 import<\/span> numpy as<\/span> np\n\n#create array\n<\/span>x = np. array<\/span> ([14, 12, 8, 10, 5, 7, 11, 9, 2]). reshape<\/span> (3,3)\n\n#view array\n<\/span>print<\/span> (x)\n\n[[14 12 8]\n [10 5 7]\n [11 9 2]]\n<\/span><\/span><\/strong><\/pre>\n
 Kita dapat menggunakan kode berikut untuk mengurutkan baris tabel NumPy dalam urutan menurun berdasarkan nilai pada kolom kedua:<\/span><\/p>\n
 #define new matrix with rows sorted in descending order by values in second column\n<\/span>x_sorted_desc = x[x[:, 1]. argsort<\/span> ()[::-1]]\n\n#view sorted matrix\n<\/span>print<\/span> (x_sorted_desc)\n\n[[14 12 8]\n [11 9 2]\n [10 5 7]]<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa baris-baris tersebut sekarang diurutkan dalam urutan menurun (dari terbesar ke terkecil) berdasarkan nilai pada kolom kedua.<\/span><\/p>\n
