在Python2.7中将字典列表转换为HTML表，不需要任何库

def dict_list_to_html_table(dict_list):
    # 检查字典列表是否为空
    if len(dict_list) == 0:
        return ""

    # 获取所有键值对的键作为表头
    headers = dict_list[0].keys()

    # 创建HTML表格的表头
    table_html = "<table><tr>"
    for header in headers:
        table_html += "<th>{}</th>".format(header)
    table_html += "</tr>"

    # 添加字典列表中的每个字典作为表格的一行
    for item in dict_list:
        table_html += "<tr>"
        for header in headers:
            table_html += "<td>{}</td>".format(item[header])
        table_html += "</tr>"

    # 关闭HTML表格
    table_html += "</table>"

    return table_html

# 示例字典列表
data = [
    {"Name": "John", "Age": 25, "City": "New York"},
    {"Name": "Emily", "Age": 30, "City": "Los Angeles"},
    {"Name": "Michael", "Age": 35, "City": "Chicago"}
]

# 转换为HTML表格
html_table = dict_list_to_html_table(data)

# 打印HTML表格
print(html_table)

<table>
  <tr>
    <th>Name</th>
    <th>Age</th>
    <th>City</th>
  </tr>
  <tr>
    <td>John</td>
    <td>25</td>
    <td>New York</td>
  </tr>
  <tr>
    <td>Emily</td>
    <td>30</td>
    <td>Los Angeles</td>
  </tr>
  <tr>
    <td>Michael</td>
    <td>35</td>
    <td>Chicago</td>
  </tr>
