Anda dapat menggunakan sintaks berikut untuk menambahkan angka nol di depan string di pandas DataFrame:<\/span><\/p>\n

 df[' ID<\/span> '] = df[' ID<\/span> ']. apply<\/span> (' {:0>7}<\/span> '. format<\/span> )\n<\/strong><\/pre>\n
 Rumus khusus ini menambahkan angka nol di depan sebanyak yang diperlukan ke string di kolom berlabel “ID” hingga setiap string memiliki panjang 7<\/strong> .<\/span><\/p>\n
 Jangan ragu untuk mengganti angka 7<\/strong> dengan nilai lain untuk menambahkan jumlah angka nol di depan yang berbeda.<\/span><\/p>\n
 Contoh berikut menunjukkan cara menggunakan sintaksis ini dalam praktiknya.<\/span><\/p>\n
 Contoh: Tambahkan Angka Nol di Depan ke String di Pandas<\/strong><\/span><\/h3>\n
 Katakanlah kita memiliki pandas DataFrame berikut yang berisi informasi tentang penjualan dan pengembalian dana dari berbagai toko:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\n\n#createDataFrame<\/span>\ndf = pd. DataFrame<\/span> ({' ID<\/span> ': ['A25', 'B300', 'C6', 'D447289', 'E416', 'F19'],\n                   ' sales<\/span> ': [18, 12, 27, 30, 45, 23],\n                   ' refunds<\/span> ': [1, 3, 3, 2, 5, 0]})\n\n#view DataFrame\n<\/span>print<\/span> (df)\n\n        ID sales refunds\n0 A25 18 1\n1 B300 12 3\n2 C6 27 3\n3 D447289 30 2\n4 E416 45 5\n5 F19 23 0\n<\/strong><\/pre>\n
 Perhatikan bahwa panjang string di kolom “ID” tidak semuanya sama.<\/span><\/p>\n
 Namun, kita dapat melihat bahwa string terpanjang adalah 7<\/strong> karakter.<\/span><\/p>\n
 Kita dapat menggunakan sintaks berikut untuk menambahkan angka nol di depan string pada kolom ‘ID’ sehingga setiap string memiliki panjang 7<\/strong> :<\/span><\/p>\n
 #add leading zeros to 'ID' column\n<\/span>df[' ID<\/span> '] = df[' ID<\/span> ']. apply<\/span> (' {:0>7}<\/span> '. format<\/span> )\n\n#view updated DataFrame\n<\/span>print<\/span> (df)\n\n        ID sales refunds\n0 0000A25 18 1\n1 000B300 12 3\n2 00000C6 27 3\n3 D447289 30 2\n4 000E416 45 5\n5 0000F19 23 0\n<\/strong><\/span><\/pre>\n
 Perhatikan bahwa angka nol di depan telah ditambahkan ke string di kolom “ID” sehingga setiap string sekarang memiliki panjang yang sama.<\/span><\/p>\n
