python - 获取可用模块

Question

使用 PHP 你有 phpinfo()其中列出了已安装的模块，然后从那里查找它们的作用。

有没有办法查看安装了哪些包/模块来导入？

Answer 1

在解释器中输入help()

然后

To get a list of available modules, keywords, or topics, type "modules",
"keywords", or "topics".  Each module also comes with a one-line summary
of what it does; to list the modules whose summaries contain a given word
such as "spam", type "modules spam".                                     

help> modules
