python - 在 jupyter notebook 的单元格中使用 sudo

Question

我正在尝试为 jupyter notebook 中的平台制作教程

有时我需要像这样在单元格中运行 linux 命令:

!sudo apt-get install blah

但不知道如何进入 sudo pass，我不想用 sudo 运行 jupyter notebook，知道怎么做吗？

Answer 1

更新:我检查了所有方法，所有方法都有效。

1:

Request password使用 getpass module它实质上隐藏了用户的输入，然后运行 ​​sudo command in python .

 import getpass
 import os

 password = getpass.getpass()
 command = "sudo -S apt-get update" #can be any command but don't forget -S as it enables input from stdin
 os.system('echo %s | %s' % (password, command))

2:

 import getpass
 import os

 password = getpass.getpass()
 command = "sudo -S apt-get update" # can be any command but don't forget -S as it enables input from stdin
 os.popen(command, 'w').write(password+'\n') # newline char is important otherwise prompt will wait for you to manually perform newline

上述方法的注意事项:

The field where you enter the password may not appear in the ipython notebook. It appears in the terminal window on a mac, and I imagine it will appear in a command shell on a PC. Even the result details would appear in the terminal.

3:

您可以将密码存储在mypasswordfile 中文件并在单元格中输入:

!sudo -S apt-get install blah < /pathto/mypasswordfile # again -S is important here

如果我想在 jupyter notebook 本身中查看命令的输出，我会更喜欢这种方法。
