Anda dapat menggunakan sintaks berikut untuk mengurangi satu pandas DataFrame dari yang lain:<\/span><\/p>\n

 df1. subtract<\/span> (df2)\n<\/strong><\/pre>\n
 Jika Anda memiliki kolom karakter di setiap DataFrame, Anda mungkin perlu memindahkannya ke kolom indeks setiap DataFrame terlebih dahulu:<\/span><\/p>\n
 df1. set_index<\/span> (' char_column<\/span> '). subtract<\/span> ( df2.set_index<\/span> (' char_column<\/span> '))<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan setiap sintaksis dalam praktiknya.<\/span><\/p>\n
 Contoh 1: Kurangi dua Pandas DataFrames (hanya kolom numerik)<\/strong><\/span><\/h2>\n
 Katakanlah kita memiliki dua panda DataFrames berikut yang hanya memiliki kolom numerik:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\n\n#create first DataFrame\n<\/span>df1 = pd. DataFrame<\/span> ({' points<\/span> ': [5, 17, 7, 19, 12, 13, 9, 24],\n                    ' assists<\/span> ': [4, 7, 7, 6, 8, 7, 10, 11]})\n\nprint<\/span> (df1)\n\n   assist points\n0 5 4\n1 17 7\n2 7 7\n3 19 6\n4 12 8\n5 13 7\n6 9 10\n7 24 11\n\n#create second DataFrame\n<\/span>df2 = pd. DataFrame<\/span> ({' points<\/span> ': [4, 22, 10, 3, 7, 8, 12, 10],\n                    ' assists<\/span> ': [3, 5, 5, 4, 7, 14, 9, 5]})\n\nprint<\/span> (df2)\n\n   assist points\n0 4 3\n1 22 5\n2 10 5\n3 3 4\n4 7 7\n5 8 14\n6 12 9\n7 10 5\n<\/span><\/span><\/span><\/strong><\/pre>\n
 Kode berikut menunjukkan cara mengurangi nilai yang sesuai antara dua DataFrame:<\/span><\/p>\n
 #subtract corresponding values between the two DataFrames<\/span>\ndf1. subtract<\/span> (df2)\n\n\tassist points\n0 1 1\n1 -5 2\n2 -3 2\n3 16 2\n4 5 1\n5 5 -7\n6 -3 1\n7 14 6\n<\/strong><\/span><\/pre>\n
 Contoh 2: Kurangi dua Pandas DataFrames (campuran kolom karakter dan numerik)<\/strong><\/span><\/h2>\n
 Katakanlah kita memiliki dua panda DataFrames berikut yang masing-masing memiliki kolom karakter bernama team<\/strong> :<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\n\n#create first DataFrame\n<\/span>df1 = pd. DataFrame<\/span> ({' team<\/span> ': ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H'],\n                    ' points<\/span> ': [5, 17, 7, 19, 12, 13, 9, 24],\n                    ' assists<\/span> ': [4, 7, 7, 6, 8, 7, 10, 11]})\n\nprint<\/span> (df1)\n\n  team points assists\n0 to 5 4\n1 B 17 7\n2 C 7 7\n3 D 19 6\n4 E 12 8\n5 F 13 7\n6 G 9 10\n7:24 a.m. 11\n\n#create second DataFrame\n<\/span>df2 = pd. DataFrame<\/span> ({' team<\/span> ': ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H'],\n                    ' points<\/span> ': [4, 22, 10, 3, 7, 8, 12, 10],\n                    ' assists<\/span> ': [3, 5, 5, 4, 7, 14, 9, 3]})\n\nprint<\/span> (df2)\n\n  team points assists\n0 to 4 3\n1 B 22 5\n2 C 10 5\n3 D 3 4\n4 E 7 7\n5 F 8 14\n6 G 12 9\n7:10 a.m. 3<\/span><\/strong><\/pre>\n
 Kode berikut menunjukkan cara memindahkan kolom tim<\/strong> ke kolom indeks setiap DataFrame, lalu mengurangi nilai yang sesuai antara kedua DataFrame:<\/span><\/p>\n
 #move 'team' column to index of each DataFrame and subtract corresponding values\n<\/span>df1. set_index<\/span> (' team<\/span> '). subtract<\/span> ( df2.set_index<\/span> (' team<\/span> '))\n\n\tassist points\nteam\t\t\nAt 1 1\nB-52\nC -3 2\nD 16 2\nE 5 1\nF 5 -7\nG -3 1\nH 14 8\n<\/span><\/strong><\/pre>\n
