I am interested in use a list of directories created in a bash script under the name list_of_dirs_in_bash and pass it to a list in my Python general program.
So, after doing in my Python script:
subprocess.call("my_bash_script.sh") do something like:
list_of_dirs_in_python = list_of_dirs_in_bash and then I can work with that list in Python. Sure it is not difficult but everything I have found is the other way around (from Python to bash). Thanks.
[Python 3.Docs]: subprocess.check_output(args, *, stdin=None, stderr=None, shell=False, cwd=None, encoding=None, errors=None, universal_newlines=None, timeout=None, text=None) is what you need (simplest variant) for this task, as it will return the process' stdout.
From there, decode and split the return value (string) to get individual lines.
Example (did everything from command line):
[cfati@cfati-ubtu16x64-0:~/Work/Dev/StackOverflow]> ls a.py q049058700 q049654022 q051914879 q052090348 q053230645 q053781370 q054269984 q055357490 q056055568 q038171543 q049499683 q051073129 q052051111 q052720961 q053626481 q054243176 q054306561 q055537728 sizes_mingwi686.exe [cfati@cfati-ubtu16x64-0:~/Work/Dev/StackOverflow]> [cfati@cfati-ubtu16x64-0:~/Work/Dev/StackOverflow]> python3 -c "import subprocess;list_of_dirs_in_bash = subprocess.check_output(['ls']).decode().split('\n');print(list_of_dirs_in_bash)" ['a.py', 'q038171543', 'q049058700', 'q049499683', 'q049654022', 'q051073129', 'q051914879', 'q052051111', 'q052090348', 'q052720961', 'q053230645', 'q053626481', 'q053781370', 'q054243176', 'q054269984', 'q054306561', 'q055357490', 'q055537728', 'q056055568', 'sizes_mingwi686.exe', '']
subprocess.call, trysubprocess.runas documented here. Passstdout=subprocess.PIPEas an arg, then use the returned CompletedProcess to access the output of your bash script.
