python

Question

'tuomastik' 在此站点上为我提供了一些很棒的代码，并对其进行了一些微调以使其适合我。然而，我花了几个小时试图编辑它，以便它打印成一个 PDF 而不是多个（一个 PDF，但每个报告都从新页面开始），但我的 HTML 并不像我想要的那样好是，我被困住了。

密码是：

HTML

<html>


<head>
    <style type="text/css">
        html, body {
            width: 500px;
            font-size: 12px;
            background: #fff;
            padding: 0px;
        }
        #my-custom-table {
            width: 500px;
            border: 0;
            margin-top: 20px;
        }
        #my-custom-table td {
            padding: 5px 0px 1px 5px;
            text-align: left;
        }
    </style>
</head>
<body>


<table cellspacing="0" border="0" style="width:500px; border:0; font-size: 14px;">
    <tr>
        <td style="text-align:left;">
            <b><span>Title of the PDF report - Row {{ row_ix + 1 }}</span></b>
        </td>
        <td style="text-align:right;">
            <b><span>{{ date }}</span></b>
        </td>
    </tr>
</table>


<table cellspacing="0" border="0.1" id="my-custom-table">
    {% for variable_name, variable_value in df.iteritems() %}
    {% if loop.index0 == 0 %}
    <tr style="border-top: 1px solid black;
               border-bottom: 1px solid black;
               font-weight: bold;">
        <td>Variable name</td>
        <td>Variable value</td>
    </tr>
    {% else %}
    <tr>
        <td>{{ variable_name }}</td>
        <td>{{ variable_value }}</td>
    </tr>
    {% endif %}
    {% endfor %}
</table>


</body>
</html>

Python

from datetime import date

import jinja2
import pandas as pd
from xhtml2pdf import pisa

df = pd.read_csv('data.csv', encoding='cp1252')

for row_ix, row in df.iterrows():

    html = jinja2.Environment(  # Pandas DataFrame to HTML
        loader=jinja2.FileSystemLoader(searchpath='')).get_template(
        'report_template.html').render(date=date.today().strftime('%d, %b %Y'),
                                       row_ix=row_ix, df=row)

    # Convert HTML to PDF
    with open('report_row_%s.pdf' % (row_ix+1), "w+b") as out_pdf_file_handle:
        pisa.CreatePDF(
            src=html,  # HTML to convert
            dest=out_pdf_file_handle)  # File handle to receive result

有人能帮忙吗？我知道我应该从 python 文件中删除 for 循环，但不确定如何处理 html 文件。

我讨厌问，但我已经尝试了一次很好的尝试，但是当我弄乱 html.

中的循环时，我无法达到运行

非常感谢
