在Ex中保存数据的问题

Question

我只想在Excel中保存数据，我找到了这段代码，它工作得很好：

import xlsxwriter

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

date = "17/08/2015"
bill = 001
item = "something"
customer = "Luis"
price = 100

# Start from the first cell. Rows and columns are zero indexed.
row = 0
col = 0

# Iterate over the data and write it out row by row.

worksheet.write(row, col, date )
worksheet.write(row, col + 1, bill)
worksheet.write(row, col + 2, item )
worksheet.write(row, col + 3, customer )
worksheet.write(row, col + 4,price)

workbook.close()

我遇到的问题是，当我试图用空格保存信息时，如果：

^{pr2}$

错误：

{cd1>试图转换字符串}。 我找到的唯一解决方案是将空格“”替换为“\

你知道我怎样在Excel中用空格保存数据吗？在

这是我所有的代码，我从文件夹中获取所有文件，稍后我转换成文本，提取一些数据后，我尝试创建一个excel文件。在

我试着编码utf-8，但没用

嗨， 我在所有导入后添加此代码。。。。现在我可以节省不间断的空间。在

import sys
reload(sys)  
sys.setdefaultencoding('Cp1252')

Answer 1

您可以尝试将脚本的编码设置为utf-8，方法是包括

# coding=utf-8

作为第一行。然后，您可以通过在其前面添加一个小写字母u将字符串编码设置为utf-8：

^{pr2}$

然后甚至可以在文本中使用非ascii字母，比如。在

或者-如前所述-在文本中使用普通空格而不是非中断空格（0xa0）。在

Answer 2

sys.setdefaultencoding('Cp1252')-这是一个令人讨厌的修复所有黑客。它掩盖了其他问题，并使代码变得脆弱和特定于平台。在

"JOSE LUIS FEBRERO LOPEZ"包含Windows-1252编码的非中断空格（0xA0）。在

xlsxwriter要求在使用非ASCII字符时传递Unicode对象。实际上，对所有字符串使用Unicode对象是一个很好的实践。在

通过在字符串前面添加u来创建Unicode对象：

u"JOSE LUIS FEBRERO LOPEZ"

由于Python源代码编码为Windows-1252，因此需要在源文件的顶部添加以下内容：

^{pr2}$

这将告诉Python如何将源文件中的字符串解码为Unicode对象。在
