问题描述

一个简单的例子,键入pip list不起作用,但是!pip list起作用.关于惊叹号和在ipython shell中使用模块有一些语法吗?

Just a quick example, typing pip list doesn't work but !pip list does. Is there some syntax regarding the exclamation point and using modules in the ipython shell?

推荐答案

这实际上并非特定于pip,而是iPython笔记本中的任何shell分配.您会注意到其他shell命令也有效(来自文档):

This is actually not specific to pip, but really any shell assignment from the iPython notebook. You'll notice other shell commands also work (from the docs):

In[1]: !pwd
/User/home/

更改目录:

In[1]: !cd /var/etc

这只是Jupyter的好人包括的简写形式.请参阅文档中的 Shell分配以了解更多的解释.

This is simply shorthand that the good folks at Jupyter have included. See Shell Assignment in the docs for more of an explanation.
