Question

我有一个Python脚本，该脚本使用pyodbc连接到SQL，并从今天起的30天内从日历返回一组值。我通过使用print（''）函数为要创建的文件生成HTML原型，然后使用Notepad ++将其复制并粘贴到HTML文件中，我知道HTML很好，并且会很好地达到其目的。但是，当涉及到生成文件时，我正在搁浅，将SQL结果包含在传递给文件编写器的变量中。

我尝试了{variable}和％v方法，它们似乎都错了；

unsupported format character ';' (0x3b) at index 1744

在％的情况下，或者在{inset}的情况下，

仅包含单词而不是var。下面是我在JN中拥有的代码；

from os import getenv
import pyodbc

cnxn = pyodbc.connect('DRIVER={ODBC Driver 13 for SQL Server};SERVER=MYSERVER\SQLEXPRESS;DATABASE=MyTable;UID=test;PWD=t')

f = open('tes.html','w')

cursor = cnxn.cursor()
cursor.execute('DECLARE @today as date SET @today = GetDate() SELECT style112, day, month, year, dayofweek, showroom_name, isbusy from ShowroomCal where Date Between @today and dateadd(month,1,@today) ')
row = cursor.fetchone()

while row is not None:
    inset = ('<div class="',row.isbusy,'"><a href="#" target="_self" title="',row.style112,'" onclick="updateValue(this.title, event);">',row.day,'</a></div>')
    row = cursor.fetchone()

任何人都可以指出一个更好的方法来包含变量吗？我需要将该插图作为此模型的数组吗？

在Windows 10上为Py3.6。

您是否尝试过将html_str保存在模板.html文件中，将插入行写成长字符串，然后将文件读入字符串，进行替换，然后重新编写文件？

 with open('C:\\template.html') as file:
      wholefile = file.readlines()

使用它来生成结果字符串。

 inset = inset + '<div class="'+ str(row.isbusy) + '"><a href="#" target="_self" title="' + str(row.style112) + '" onclick="updateValue(this.title, event);">' + str(row.day) + '</a></div>' + '\n'

然后进行替换，因此您将完整的文件放在一个字符串中，然后将其写回。

wholefile.replace('{inset}',inset)

Python：将SQL生成的变量写入HTML文件
