【问题描述】：

我正在创建一个从 highcharts.com 下载其内容的 HTML 文件。默认 HTML 内容的头部如下所示

<head>
        <meta charset="utf-8" />
        <link href="https://www.highcharts.com/highslide/highslide.css" rel="stylesheet" />
        <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
        <script type="text/javascript" src="https://code.highcharts.com/6/highcharts.js"></script>
        <script type="text/javascript" src="https://code.highcharts.com/6/highcharts-more.js"></script>
        <script type="text/javascript" src="https://code.highcharts.com/6/modules/heatmap.js"></script>
        <script type="text/javascript" src="https://code.highcharts.com/6/modules/exporting.js"></script>
    </head>

我想将其替换为：

<head>
        <meta charset="utf-8" />
        <link href="https://www.highcharts.com/highslide/highslide.css" rel="stylesheet" />
        <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
        <script src="https://code.highcharts.com/highcharts.js"></script>
        <script src="https://code.highcharts.com/modules/series-label.js"></script>
        <script src="https://code.highcharts.com/modules/exporting.js"></script>
        <script src="https://code.highcharts.com/modules/export-data.js"></script>
        <script src="https://code.highcharts.com/modules/accessibility.js"></script>

        <figure class="highcharts-figure">
            <div id="container"></div>
            <p class="highcharts-description">
                Basic line chart showing trends in a dataset. This chart includes the
                <code>series-label</code> module, which adds a label to each line for
                enhanced readability.
            </p>
        </figure>

    </head>

我正在使用下面的代码来编写来自 highcharts.com (H) 的 HTML 中的默认内容

# write out the html
FileName1 = "Highcharts_Test.html"
with open(FileName1, "wt") as fh:
    fh.write(H.htmlcontent)

我怎样才能实现上述目标？

【问题讨论】：

如果你有它作为字符串，那么你可以使用标准的字符串函数，如text_html.replace("</head>", "some_text </head>")
它不起作用。线条太长。 text_html.replace 是 python 库的一部分或者我需要导入 Html？
它是标准函数 "Hello World".replace("Hello", "Goodbye") 并且您可以将变量与文本 "Hello World".replace(variable1, variable2) 一起使用，因此您可以使用三重 " - variable = """here text in many lines""" 分配多行文本，或者您可以从文件 @987654329 中读取此文本@

【解决方案1】：

您可以使用标准的replace() 将"</html>" 替换为"some text </html>"

html = '''<head>
        <meta charset="utf-8" />
        <link href="https://www.highcharts.com/highslide/highslide.css" rel="stylesheet" />
        <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
        <script type="text/javascript" src="https://code.highcharts.com/6/highcharts.js"></script>
        <script type="text/javascript" src="https://code.highcharts.com/6/highcharts-more.js"></script>
        <script type="text/javascript" src="https://code.highcharts.com/6/modules/heatmap.js"></script>
        <script type="text/javascript" src="https://code.highcharts.com/6/modules/exporting.js"></script>
</head>'''

new = '''
        <figure class="highcharts-figure">
            <div id="container"></div>
            <p class="highcharts-description">
                Basic line chart showing trends in a dataset. This chart includes the
                <code>series-label</code> module, which adds a label to each line for
                enhanced readability.
            </p>
        </figure>

</head>'''


html = html.replace('</head>', new)

print(html)
