用多列写excel文档
嗨，大家好我在这里得到一个奇怪的错误，不知道是什么问题。 不幸的是有太多的可能性，我无法弄清楚。我有一些时间string，我从数据库中返回。 我想把它们放进一个带有一些随机生成值的Excel电子表格中。 任何想法将不胜感激:)
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() OUTPUT

每次都会在循环中覆盖dates 。 所以当你在列表上迭代时，它不起作用，因为它仅仅是一个列表，而不是一对夫妇的列表。 第一次迭代产生"date" ，不能被解压缩成2个variables。
首先定义dates列表为空，然后为每个迭代追加列表。
expenses = [] # you're doing that all right # Some data we want to write to the worksheet. for T in list1: ... expenses.append(['date', 1234])
现在你可以迭代夫妻并解开价值。
