Anda dapat menggunakan sintaks dasar berikut untuk mendapatkan baris pertama setiap grup dalam pandas DataFrame:<\/span><\/p>\n

 df. groupby<\/span> (' column_name<\/span> '). nth<\/span> ( 0<\/span> )\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan sintaksis ini dalam praktiknya.<\/span><\/p>\n
 Contoh: Dapatkan baris pertama setiap grup di Pandas<\/strong><\/span><\/h3>\n
 Misalkan kita memiliki panda DataFrame berikut:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\n\n#createDataFrame\n<\/span>df = pd. DataFrame<\/span> ({' team<\/span> ': ['A', 'A', 'B', 'B', 'B', 'C', 'C', 'C'],\n                   ' points<\/span> ': [18, 22, 19, 14, 14, 11, 20, 29],\n                   ' assists<\/span> ': [5, 19, 14, 8, 9, 12, 13, 8]})\n\n#view DataFrame\n<\/span>df\n\n\tteam points assists\n0 to 18 5\n1 To 22 19\n2 B 19 14\n3 B 14 8\n4 B 14 9\n5 C 11 12\n6 C 20 13\n7 C 29 8\n<\/strong><\/span><\/pre>\n
 Kita dapat menggunakan kode berikut untuk mendapatkan baris pertama untuk setiap tim:<\/span><\/p>\n
 #get first row for each team\n<\/span>df. groupby<\/span> (' team<\/span> '). nth<\/span> ( 0<\/span> )\n\n\tassist points\nteam\t\t\nAt 18 5\nB 19 14\nC 11 12<\/span><\/span><\/strong><\/pre>\n
 Kita juga dapat menentukan as_index=False<\/strong> untuk mempertahankan nilai indeks asli:<\/span><\/p>\n
 #get first row for each team, keep original index values<\/span>\ndf. groupby<\/span> (' team<\/span> ', as_index= False<\/span> ). nth<\/span> ( 0<\/span> )\n<\/span>\n        team points assists\n0 to 18 5\n2 B 19 14\n5 C 11 12<\/span><\/span><\/strong><\/pre>\n
 Perhatikan juga bahwa Anda dapat meneruskan daftar nilai ke fungsi nth()<\/strong> jika Anda ingin mendapatkan n baris pertama dari setiap grup.<\/span><\/p>\n
 Misalnya, kode berikut menunjukkan cara mendapatkan dua baris pertama dari setiap grup:<\/span><\/p>\n
 #get first two rows for each team, keep original index values\n<\/span>df. groupby<\/span> (' team<\/span> ', as_index= False<\/span> ). nth<\/span> (( 0,1<\/span> )<\/span> )\n<\/span>\nteam points assists\n0 to 18 5\n1 To 22 19\n2 B 19 14\n3 B 14 8\n5 C 11 12\n6 C 20 13<\/span><\/span><\/strong><\/pre>\n
