In python is os.sytem( ... ) blocking or not??

Question

In python, when you do os.system( 'subprocess')
is the python calling fork blocked while the subprocesses fork is run, or do they run concurrently???

Answer 1

os.system() calls the C function system(). It spawns a separate process, the implementation is different in each operating system.
It is advised to use subprocess.call() instead.
Check the official docs
https://docs.python.org/3.8/library/os.html#os.system
