Anda dapat menggunakan sintaks dasar berikut untuk menetapkan nilai sel tertentu di pandas DataFrame:<\/span><\/p>\n

 #set value at row index 0 and column 'col_name' to be 99<\/span>\ndf. at<\/span> [0, ' col_name<\/span> '] = 99\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan sintaksis ini dalam praktiknya dengan pandas DataFrame berikut:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\n\n#createDataFrame\n<\/span>df = pd. DataFrame<\/span> ({' points<\/span> ': [25, 12, 15, 14, 19, 23, 25, 29],\n                   ' assists<\/span> ': [5, 7, 7, 9, 12, 9, 9, 4],\n                   ' rebounds<\/span> ': [11, 8, 10, 6, 6, 5, 9, 12]})\n\n#view DataFrame\n<\/span>df\n\n\tpoints assists rebounds\n0 25 5 11\n1 12 7 8\n2 15 7 10\n3 14 9 6\n4 19 12 6\n5 23 9 5\n6 25 9 9\n7 29 4 12<\/strong><\/pre>\n
 Contoh 1: Tetapkan nilai sel di Pandas<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara mengatur nilai posisi indeks ke-3 kolom “poin” menjadi 99:<\/span><\/p>\n
 #set value in 3rd index position and 'points' column to be 99<\/span>\ndf. at<\/span> [3, ' points<\/span> '] = 99\n\n#view updated DataFrame<\/span>\ndf\n\n        points assists rebounds\n0 25 5 11\n1 12 7 8\n2 15 7 10\n3 99 9 6\n4 19 12 6\n5 23 9 5\n6 25 9 9\n7 29 4 12\n<\/strong><\/pre>\n
 Perhatikan bahwa nilai pada posisi indeks ke-3 kolom “poin” telah diubah dan semua nilai lainnya di DataFrame tetap sama.<\/span><\/p>\n
 Contoh 2: Tetapkan nilai beberapa sel di Pandas<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara mengatur nilai beberapa sel dalam suatu rentang secara bersamaan:<\/span><\/p>\n
 #set values in index positions 0 to 3 in 'points' column to be 99<\/span> \ndf. at<\/span> [0:3, ' points<\/span> '] = 99\n\n#view updated DataFrame<\/span>\ndf\n\n<\/span>points assists rebounds\n0 99 5 11\n1 99 7 8\n2 99 7 10\n3 99 9 6\n4 19 12 6\n5 23 9 5\n6 25 9 9\n7 29 4 12\n<\/strong><\/pre>\n
 Contoh 3: Tetapkan Nilai Secara Bersyarat di Pandas<\/strong><\/h3>\n
 Kode berikut menunjukkan cara mengatur nilai pada kolom “rebound” menjadi 99 hanya jika<\/em> nilai pada kolom poin lebih besar dari 20:<\/span><\/p>\n
 #set values in 'rebounds' column to be 99 if value in points column is greater than 20\ndf. loc<\/span> [df[' points<\/span> ']>20, [' rebounds<\/span> ']] = 99<\/span>\n\n#view updated DataFrame\ndf<\/span>\n\npoints assists rebounds\n0 25 5 99\n1 12 7 8\n2 15 7 10\n3 14 9 6\n4 19 12 6\n5 23 9 99\n6 25 9 99\n7 29 4 99\n<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa setiap nilai pada kolom rebound diubah menjadi 99 jika nilai pada kolom poin lebih besar dari 20.<\/span><\/p>\n
 Semua nilai lainnya tetap sama.<\/span><\/p>\n
