退出python程序后调用bash脚本

Question

I'm new to Python and have been able to find answers to most of my questions here so I thought you guys could help me with this one:

I'm developing somewhat of a hybrid application using bash scripts to show menus and to call python applications (I'm doing it this way to simplify things).

My problem is that when I end the python application, it simply terminates the process and to go back to the menus, I have to start the whole program again. I tried using "subprocess.call('xxx')" but it opens the bash scrips inside of the application I am running and shows text (echo) only, no other functions.

Is there a way to end the python application first and then call the shell script?

You can wrap your code in a while-true loop

while :; do
    # Assuming you want to show the menu before you start a program:
    bash showMenu.py
    python myScript.py
    # When the above scripts exits the process will start all over again
    # You might want to consider checking the exit code and only continue if the program exits with status code 0
    # [ $? gt 0 ] && break
done
