如何向 Popen() 传递多个输入参数？

Question

我正在编写一个为用户安装命令行界面的脚本。proc = Popen("sudo -S apt-get install vim".split(), stdin=PIPE, stdout=PIPE, stderr=PIPE, shell=True)# Popen only accepts byte-arrays so you must encode the stringoutput = proc.communicate(password.encode())stdoutput = (output)[0].decode('utf-8')输出：Installing Vim...|Reading package lists...Building dependency tree...Reading state information...The following additional packages will be installed:  vim-runtimeSuggested packages:  ctags vim-doc vim-scriptsThe following NEW packages will be installed:  vim vim-runtime0 upgraded, 2 newly installed, 0 to remove and 5 not upgraded.Need to get 7,111 kB of archives.After this operation, 34.6 MB of additional disk space will be used.Do you want to continue? [Y/n] Abort.如您所见，软件包的安装停止Do you want to continue?，并且由于某种原因，安装被中止。我如何y在这个阶段使用传递 a Popen()？我已经使用传递密码communicate()，但没有进行多次输入。

-y只需作为选项传递apt-get即可避免与它（进一步）交互的需要。

proc = Popen(["sudo", "-S", "apt-get", "-y", "install", "vim"], stdin=PIPE, stdout=PIPE, stderr=PIPE)

output, error = proc.communicate(password.encode())

stdoutput = output.decode('utf-8')
