如何使用Python Regex在HTML脚本中检索javascript变量？

import re

def retrieve_javascript_variables(html_script):
    pattern = r'var\s+(\w+)\s*=\s*(.*?);'
    matches = re.findall(pattern, html_script)
    variables = {}
    for match in matches:
        variable_name = match[0]
        variable_value = match[1]
        variables[variable_name] = variable_value
    return variables

# 示例HTML脚本
html_script = '''
<script>
    var name = "John";
    var age = 25;
    var isStudent = true;
</script>
'''

# 调用函数检索JavaScript变量
javascript_variables = retrieve_javascript_variables(html_script)

# 输出检索到的JavaScript变量
for variable_name, variable_value in javascript_variables.items():
    print(f"{variable_name}: {variable_value}")

name: "John"
age: 25
isStudent: true
