Anda dapat menggunakan sintaks berikut untuk mengganti string kosong dengan nilai NaN di panda:<\/span><\/p>\n

 df = df. replace<\/span> ( r'^\\s*$'<\/span> , np. nan<\/span> , regex= True<\/span> )<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan sintaksis ini dalam praktiknya.<\/span><\/p>\n

 Misalkan kita memiliki pandas DataFrame berikut yang berisi informasi tentang berbagai pemain bola basket:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\n\n#createDataFrame\n<\/span>df = pd. DataFrame<\/span> ({' team<\/span> ': ['A', 'B', ' ', 'D', 'E', ' ', 'G', 'H'],\n                   ' position<\/span> ': [' ', 'G', 'G', 'F', 'F', ' ', 'C', 'C'],\n                   ' points<\/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\tteam position points rebounds\n0 to 5 11\n1 B G 7 8\n2 G 7 10\n3 D F 9 6\n4 E F 12 6\n5 9 5\n6 G C 9 9\n7 H C 4 12<\/strong><\/pre>\n
 Perhatikan bahwa ada beberapa string kosong di kolom tim<\/strong> dan posisi<\/strong> .<\/span><\/p>\n
 Kita dapat menggunakan sintaks berikut untuk mengganti string kosong ini dengan nilai NaN:<\/span><\/p>\n
 import<\/span> numpy as<\/span> np<\/span>\n\n#replace empty values with NaN\n<\/span>df = df. replace<\/span> ( r'^\\s*$'<\/span> , np. nan<\/span> , regex= True<\/span> )\n<\/span>\n#view updated DataFrame\ndf\n<\/span>\nteam position<\/span> points rebounds\n0 A NaN<\/span> 5 11\n1 B G<\/span> 7 8\n2 NaN G<\/span> 7 10\n3 D F<\/span> 9 6\n4 E F<\/span> 12 6\n5 NaN NaN<\/span> 9 5\n6 G C<\/span> 9 9\n7 H C<\/span> 4 127<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa setiap string kosong telah diganti dengan NaN.<\/span><\/span><\/p>\n
