How can I do this with python ?

[Xiao Jianfeng]

Dear all,

In a shell script, I can run a command which need interactive input like
this,

#!/bin/sh

A_Command<<-EOF
a
b
c
EOF

But, how can I do this with python ?

Thanks in advance.

Re: How can I do this with python ?

Your question is insufficiently clear for me to answer.

Do you want to know how to read from standard-input in a Python
program?

Do you want to know how to start an external program from Python, and
then connect something to that programs standard input?

Do you want to know something else?

Please specify!

Cheers,

Thanks.

For example, I can call vim and do something like this in a shell script,

#!/bin/sh

vim a.file<<-EOF
:some_vim_comma nd
:some_vim_comma nd
:w
:q
EOF

I want to know how to call vim and to the same thing with python.

Regrads,

hi,

os.popen should do that.

Better go for the subprocess module. It is supposed to replace os.popen
and has a much nicer interface.
