I have a program that interacts with the user (acts like a shell), and I want to run it using the Python subprocess module interactively.
That means, I want the possibility to write to standard input and immediately get the output from standard output. I tried many solutions offered here, but none of them seems to work for my needs.
Is there a way to programmatically force a Python script to drop into a REPL at an arbitrary point in its execution, even if the script was launched from the command line?
Scenario: An interactive CLI Python program, that is in need for a password. That means also, there’s no GUI solution possible.
I want to write a program (in Python 3.x on Windows 7) that executes multiple commands on a remote shell via ssh. After looking at paramikos’ exec_command() function, I realized it’s not suitable for my use case (because the channel gets closed after the command is executed), as the commands depend on environment variables (set by prior commands) and can’t be concatenated into one exec_command() call as they are to be executed at different times in the program.
I need to determine whether the shell which invoked my Python script was in interactive mode or not. If it was in interactive mode, the program should pipe output to less(1) for easy reading. If not, it should simply print its output to stdout, to allow it to be piped away to a printer, file, or a different pager.
In a Python script, is there any way to tell if the interpreter is in interactive mode? This would be useful so that, for instance, when you run an interactive Python session and import a module, slightly different code is executed (for example, logging is turned off).
I am executing a long-running python script via ssh on a remote machine using paramiko. Works like a charm, no problems so far.
