你可以创建一个函数并替换参数。
例如：

def request_function(host, param, value, user, passwd):
    try:
        host = f'http://{host}?{param}={value},{user}{password}'
        response = requests.get(host)
        return [True, response.status_code, response.text]
    except:
        try:
            host = f'http://{host}?{param}={value}&{user}{password}'
            response = requests.get(host)
            return [True, response.status_code, response.text]
        except:
            try:
                host = f'http://{host}?{param}&{user}{password}'
                response = requests.get(host)
                return [True, response.status_code, response.text]
            except:
                return [False, 0, 'No works']

取决于哪一个工作，你可以删除其他的try块。

这需要一些修改，但现在我自己找到了一个解决方案，线索是认识到请求是可以准备的，并且所谓的PreparedRequest是完全可变的，正如手册www.example.com中所述https://requests.readthedocs.io/en/latest/api/#requests.PreparedRequest（后面是一个用法示例）：
类请求。已准备请求
完全可变的PreparedRequest对象，包含将发送到服务器的确切字节数。
因此，当他们声称它是完全可变的时，我应该能够根据需要调整PreparedRequest。
下面的代码显示了这一点，它向anel outlet发出了两个不同的请求。它首先生成一个Request对象，然后准备它，从而产生一个PreparatedRequest示例。在准备好的请求中，修改url，去掉一些占位符，只用于位置参数。然后，修改后的请求被发送到outlet。
额外的代码实际上需要7个LLOC，这在大多数情况下应该是合理的。剩下的只是测试代码和调试输出的代码。在本例中，给定的user和pass是出厂默认值，需要用实际的user和pass替换。

import requests
from requests import session, Request

BASE_URL = "http://192.168.0.245"

def request_hack(url: str = BASE_URL, params: dict = None) -> requests.PreparedRequest:
    DUMMY = "dummy"

    if isinstance(params, dict):
        # The requests lib would normally ignore params mapping to None,
        # but if we replace the None values using some DUMMY the resulting
        # url can be conditioned to strip the superfluous assignments in
        # the positional only parameters
        params = {k: v or DUMMY for k, v in params.items()}

    # The request cannot be sent directly as the URL syntax for the anel outlets is not supported by the requests lib
    # Therefore, we first set-up a PreparedRequest and then modify the url to our needs
    req = Request("GET", url, params=params).prepare()
    print(f"Unconditioned request {req.url}")
    # Remove the DUMMY values and the preceeding equal signs by replacing them with empty strings
    req.url = req.url.replace(f"={DUMMY}", "")
    print(f"Conditioned request {req.url}")

    return req

if __name__ == "__main__":
    the_session = session()

    """ Perform a Stat request to the anel outlet """
    req = request_hack(params={"Stat": None, "adminanel": None})
    res = the_session.send(req)
    print(res.text)

    """ Perform a Switch request to the anel outlet """
    req = request_hack(params={"Sw": "0x55", "adminanel": None})
    res = the_session.send(req)
    print(res.text)

示例代码将输出如下内容：
