Question

我想将xls文件中的数据显示到HTML表中。我使用openpyxl从xls文件中读取数据。我使用HTML代码使用HTML标签创建表，但我无法使用变量将数据放入表中。我能够打印sheet['A2']并查看xls文件中的值。我已将此值分配给变量a2。如何在HTML中打印此变量的值。更具体地说，如何将变量的值放在此标记中：<tr><td class="cell">{%sheet['A2']%}</td> <td class="cell">Cell 1.2</td></tr>

   import smtplib
   import openpyxl
   from email.mime.multipart import MIMEMultipart
   from email.mime.text import MIMEText
   from email.mime.base import MIMEBase
   from email import encoders

   def py_mail(SUBJECT, BODY, TO, FROM):
    """With this function we send out our html email"""


   book = 
   openpyxl.load_workbook('D:\download\DAILY_PROJECT_REPORT20180420.xlsx')
   sheet = book.active

   a2 = sheet['A2']



     # Record the MIME type text/html.
      HTML_BODY = MIMEText(BODY, 'html')

     if __name__ == "__main__":
 """Executes if the script is run as main script (for testing purposes)"""

     email_content = """
     <head>
     <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
      <title>html title</title>
      <style type="text/css" media="screen">
      table {
      border-collapse: collapse;
       }

      table, td, th {
      border: 1px solid black;
       border-collapse: collapse;
       border-spacing: 5px;
      }
     </style>
     </head>
     <body>

    <table style="width:70%">
       <tr>
    <th> PREPAC </th>
    <th> TEAM_STATUS </th>
    <th> TOTAL </th>
    </tr>
    <tr><td class="cell">{%sheet['A2']}%</td><td class="cell">Cell 1.2</td> 
     </tr>
     <tr><td class="cell">Cell 2.1</td><td class="cell"></td></tr>

    </table>

    </body>
    """

     py_mail("Test email subject", email_content, TO, FROM)

一种方法是使用string formatting：

>>> html = """<td>{}</td>"""
>>> s1A2 = 10
>>> print(html.format(s1A2))
<td>10</td>

或使用f-strings：

>>> print(f"""<td>{s1A2}</td>""")
<td>10</td>
>>>

或者在格式字符串中使用带有字典的命名替换字段

>>> data = {'s1A2':10}
>>> html = """<td>{s1A2:}</td>"""
>>> print(html.format(**data))
<td>10</td>
>>>

你的字符串：

s = """<tr><td class="cell">{%sheet['A2']}%</td><td class="cell">Cell 1.2</td>"""

如果使用Python版本3.6+使用f-string：

print(f"""<tr><td class="cell">{sheet['A2']}%</td><td class="cell">Cell 1.2</td>"""

或使用传统格式;

print("""<tr><td class="cell">{}%</td><td class="cell">Cell 1.2</td>""".format(sheet['A2']))

使用python lib中的数据创建HTML表
