將數據導出到 Excel 時出現 Pandas 錯誤

Question

獲取熊貓錯誤為：ValueError：操作數無法與形狀一起廣播 (4,) (2,2)

嘗試在 excel 中導出詳細信息，我嘗試使用以下代碼：

預期輸出：選定的客戶名稱：名稱 1、名稱 2 用於設計：CUST 選定的客戶名稱：值名稱 3、名稱 4 用於設計：ORDER

已嘗試以下代碼：

import pandas as pd
import xlsxwriter

workbook   = xlsxwriter.Workbook('file.xlsx')
worksheet1 = workbook.add_worksheet()

def CUST1(): 
    df = pd.DataFrame([
    ['CUST', 'name1', 'PIZZA', 'A'],
    ['CUST', 'name2', 'DONUT', 'A'],
    ['ORDER', 'name3', 'CAKE','B'],
    ['ORDER', 'name4', 'COOKIES', 'C']
    ],
    columns=("DESIG", "NAMES", "CITIES", "CLASS"))
    ORD = pd.concat((df['DESIG'],df.groupby('DESIG') 
    ['NAMES'].transform(lambda x: ", ".join(x))), 
    axis=1).drop_duplicates()
    print(ORD)
    for x, name in enumerate(ORD):
     worksheet1.write(x, 0, "selected customer names" 
     + df['DESIG'] + "for" +df.groupby('DESIG') 
     ['NAMES'])
CUST1()
workbook.close()

Answer 1

根據提供的預期輸出，這應該是您想要的。 我只是使用了 dataFrame ORD，因為它包含所有必要的信息，而無需進行更多的數據轉換。

import pandas as pd
import xlsxwriter

workbook   = xlsxwriter.Workbook('file.xlsx')
worksheet1 = workbook.add_worksheet()

def CUST1(): 
    df = pd.DataFrame([
    ['CUST', 'name1', 'PIZZA', 'A'],
    ['CUST', 'name2', 'DONUT', 'A'],
    ['ORDER', 'name3', 'CAKE','B'],
    ['ORDER', 'name4', 'COOKIES', 'C']
    ],
    columns=("DESIG", "NAMES", "CITIES", "CLASS"))
    ORD = pd.concat((df['DESIG'],df.groupby('DESIG') 
    ['NAMES'].transform(lambda x: ", ".join(x))), 
    axis=1).drop_duplicates()

    for x in range(len(ORD)):
        worksheet1.write_string(x, 0, "selected customer names: " 
         + ORD['NAMES'].iloc[x] + " for the desig: " +  ORD['DESIG'].iloc[x])
CUST1()
workbook.close()
