Anda dapat menggunakan sintaks berikut untuk menghitung jumlah kumulatif per grup di panda:<\/span><\/p>\n

 df[' cumsum_col<\/span> '] = df. groupby<\/span> ([' col1<\/span> '])[' col2<\/span> ']. cumsum<\/span> ()\n<\/strong><\/pre>\n
 Rumus khusus ini menghitung jumlah kumulatif col2<\/strong> , dikelompokkan berdasarkan col1<\/strong> , dan menampilkan hasilnya di kolom baru berjudul cumsum_col<\/strong> .<\/span><\/p>\n
 Contoh berikut menunjukkan cara menggunakan sintaksis ini dalam praktiknya.<\/span><\/p>\n
 Contoh: hitung jumlah kumulatif per grup di Pandas<\/strong><\/span><\/h3>\n
 Katakanlah kita memiliki pandas DataFrame berikut yang berisi informasi penjualan untuk berbagai toko:<\/span><\/p>\n
 import<\/span> pandas as<\/span> pd\n\n#createDataFrame<\/span>\ndf = pd. DataFrame<\/span> ({' store<\/span> ': ['A', 'A', 'A', 'A', 'A', 'B', 'B', 'B', 'B', 'B'],\n                   ' sales<\/span> ': [4, 7, 10, 5, 8, 9, 12, 15, 10, 8]})\n\n#view DataFrame\n<\/span>print<\/span> (df)\n\n  blind sales\n0 to 4\n1 to 7\n2 to 10\n3 to 5\n4 to 8\n5 B 9\n6 B 12\n7 B 15\n8 B 10\n9 B 8<\/strong><\/pre>\n
 Kita dapat menggunakan sintaks berikut untuk menghitung jumlah kumulatif penjualan untuk setiap toko:<\/span><\/p>\n
 #add column that shows cumulative sum of sales by store\ndf[' cumsum_sales<\/span> '] = df. groupby<\/span> ([' store<\/span> '])[' sales<\/span> ']. cumsum<\/span> ()\n<\/span>\n#view updated DataFrame\n<\/span>print<\/span> (df)\n\n  store sales cumsum_sales\n0 to 4 4\n1 to 7 11\n2 to 10 21\n3 to 5 26\n4 to 8 34\n5 B 9 9\n6 B 12 21\n7 B 15 36\n8 B 10 46\n9 B 8 54\n<\/span><\/span><\/strong><\/span><\/pre>\n
 Kolom cumsum_sales<\/strong> menampilkan penjualan kumulatif yang dikelompokkan berdasarkan masing-masing toko.<\/span><\/span><\/p>\n
