python - Python 空请求响应处理

Question

如何确保请求为空（由于 url 是一个不存在的网页，其余代码可以执行？什么是聪明的方法呢？

if __name__ == '__main__':
    request = get_request(url)
    status_code = get_status_code(request)
    content_length = get_content_length(request)
    date = get_date(request)

def get_request(url):
    response = ["empty"]
    try:
        response = requests.get(url)
        response.raise_for_status()
    except requests.exceptions.HTTPError as errh:
        print("Http Error:", errh)
        pass
    except requests.exceptions.ConnectionError as errc:
        print("Error Connecting:", errc)
        pass
    except requests.exceptions.Timeout as errt:
        print("Timeout Error:", errt)
        pass
    except requests.exceptions.RequestException as err:
        print("Oops: Something Else", err)
        pass
    return response
