創建動態表變量

我有以下數據列表：創建動態表變量

month = [ "Jan", "Feb", "Mar", "Apr" ]

每個月的數據存儲在JSON，如：

[{"Master" : [ 
     { 
      "month" : "Jan", 
      "Expense" : "50", 
      "Income" : "100", 
      "Emp" : "1" 
     }, 
     { 
      "month" : "Jan", 
      "Expense" : "500", 
      "Income" : "1000", 
      "Emp" : "2" 
     }, 
     { 
      "month" : "Feb", 
      "Expense" : "50", 
      "Income" : "100", 
      "Emp" : "1" 
     }, 
     { 
      "month" : "Feb", 
      "Expense" : "500", 
      "Income" : "1000", 
      "Emp" : "2" 
     }, 
     { 
      "month" : "Mar", 
      "Expense" : "50", 
      "Income" : "100", 
      "Emp" : "2" 
     }, 
     { 
      "month" : "Apr", 
      "Expense" : "50", 
      "Income" : "100", 
      "Emp" : "1" 
     } 
    ] 
}]

取決於month的價值，我需要寫所有使用for loop來分隔名稱爲「Jan」，「Feb」，「Mar」，「Apr」等的工作表的每月數據內容，如下所示：

for i in range(len(month)): 
    worksheet[i] = workbook.add_worksheet(month[i])

列表month中的內容可能會更改，因此需要動態變量分配。

這可能嗎？

是的，這應該是可能的。爲什麼不嘗試，在問之前？ –

我在'workbook.close（）'上遇到'SyntaxError：invalid Syntax'錯誤。 – Jagath

然後你應該在問題中添加你使用的代碼，你得到的錯誤。 –

以下應該做你正在尋找的東西。你可以配置哪些列和月是必需的：

import xlsxwriter 
import itertools 

data = [{"Master" : [ 
     { 
      "month" : "Jan", 
      "Expense" : "50", 
      "Income" : "100", 
      "Emp" : "1" 
     }, 
     { 
      "month" : "Jan", 
      "Expense" : "500", 
      "Income" : "1000", 
      "Emp" : "2" 
     }, 
     { 
      "month" : "Feb", 
      "Expense" : "50", 
      "Income" : "100", 
      "Emp" : "1" 
     }, 
     { 
      "month" : "Feb", 
      "Expense" : "500", 
      "Income" : "1000", 
      "Emp" : "2" 
     }, 
     { 
      "month" : "Mar", 
      "Expense" : "50", 
      "Income" : "100", 
      "Emp" : "2" 
     }, 
     { 
      "month" : "Apr", 
      "Expense" : "50", 
      "Income" : "100", 
      "Emp" : "1" 
     } 
    ] 
}] 


workbook = xlsxwriter.Workbook('output.xlsx') 

# List of required months 
months = [ "Jan", "Feb", "Apr" ]  

# List of required columns and required order 
columns = ['month', 'Expense', 'Income', 'Emp'] 

for workbook_month in months: 
    for data_month, g in itertools.groupby(data[0]['Master'], key=lambda x: x['month']): 
     if workbook_month == data_month: 
      worksheet = workbook.add_worksheet(workbook_month) 
      worksheet.write_row(0, 0, columns) 

      for row, entry in enumerate(g, start=1): 
       worksheet.write_row(row, 0, [entry[col] for col in columns]) 

workbook.close()

給你下面的輸出，在這裏，我已經錯過了Mar數據：

謝謝馬丁。這有幫助。 – Jagath
