複数の列を使用してExcel文書を書き込む

Question

こんにちは、ここでは奇妙なエラーが発生しています。残念ながら、私はそれを理解することができないほど多くの可能性があります。私は、データベースから戻ってくるいくつかのタイムストリングを持っています。ランダムに生成されたいくつかの値を使って、それらをスプレッドシートに入れたいと思います。任意のアイデアをいただければ幸いです:)

import xlsxwriter 

# Create a workbook and add a worksheet. 
workbook = xlsxwriter.Workbook('Expenses042.xlsx') 
worksheet = workbook.add_worksheet() 

# Add a bold format to use to highlight cells. 
bold = workbook.add_format({'bold': True}) 


# Write some data headers. 
worksheet.write('A1', 'Facility', bold) 
worksheet.write('B1', 'Type', bold) 

# Some data we want to write to the worksheet. 
expenses=[] 
for T in list1: 
    FM = random.randint(0,13) 
    RUL = random.randint(1,365) 
    SL = random.randint(0,4) 
    S = str(T['value']) 
    expenses= (['rent', S]) 
    print expenses 

# Start from the first cell below the headers. 
row = 1 
col = 0 

# Iterate over the data and write it out row by row. 
for item, cost in (expenses): 
    worksheet.write(row, col,  item) 
    worksheet.write(row, col + 1, cost, money) 
    row += 1 

workbook.close()

Answer 1

。だからあなたがリストを反復するとき、それは単なるリストであり、カップルのリストではないので動作しません。最初の反復は"date"となり、2つの変数にアンパックすることはできません。

最初にdatesリストを空として定義し、各繰り返しに対してリストを追加します。

expenses = [] # you're doing that all right 
# Some data we want to write to the worksheet. 
for T in list1: 
    ... 
    expenses.append(['date', 1234]) 

これで、カップルを反復して値をアンパックすることができます。
