Python 2 的网络浏览器在 repl.it 中无法使用
Python 2's webbrowser is not working in repl.it
我正在使用 repl.it，以及使用 webbrowser.open(< 打开 link 的网络浏览器模块link打开>)
但是，我的 link 不起作用。你能帮我吗？
这是我的代码：
import webbrowser
webbrowser.open("https://www.daffodilday.com.au/get-involved/register-your-school/", 2)

你能帮帮我吗？我几乎了解 Python 中的所有内容，但有时仍然需要相当多的努力。
您可以这样简化答案：
import webbrowser
webbrowser.open(*website*)
当然把*website*换成site就不用写2了。
然后告诉我它是否有效。
顺便说一句，一些在线 python 处理器，如 pythonanywhere 不允许打开所有网站。
相反，他们只允许某些特定网站。
我正在使用 repl.it，以及使用 webbrowser.open(< 打开 link 的网络浏览器模块link打开>) 但是，我的 link 不起作用。你能帮我吗？ 这是我的代码：
import webbrowser
webbrowser.open("https://www.daffodilday.com.au/get-involved/register-your-school/", 2)

你能帮帮我吗？我几乎了解 Python 中的所有内容，但有时仍然需要相当多的努力。
您可以这样简化答案：
import webbrowser
webbrowser.open(*website*)
当然把*website*换成site就不用写2了。 然后告诉我它是否有效。
顺便说一句，一些在线 python 处理器，如 pythonanywhere 不允许打开所有网站。 相反，他们只允许某些特定网站。
