    试了下应该是 error 的类型错了

    #!/usr/bin/python
    import urllib.request
    import urllib.error

    try:
    respOnse= urllib.request.urlopen('https://www.baidu.com',timeout=2)
    html = response.read().decode('utf-8')
    print(html)
    except:
    print('error')

    打印的结果如下:
    <html>
    <head>
    <script>
    location.replace(location.href.replace("https://","http://"));
    </script>
    </head>
    <body>
    <noscript><meta http-equiv="refresh" cOntent="0;url=http://www.baidu.com/"></noscript>
    </body>
    </html>

    ```
    import urllib.request
    import urllib.error

    try:
    respOnse= urllib.request.urlopen('https://www.baidu.com',timeout=2)
    html = response.read().decode('utf-8')
    print(html)
    except urllib.error.HTTPError as e:
    print('error')
    ```
    是没问题的。
    输出的 html 也正常

    @wellsc 这个不合规。python3 的可执行文件不能叫 python,只能叫 python3
