I have to run a C program by my Python script. I have already compiled the C program and I need to call it from Python to execute it.

I've used the subprocess.Popen class to do so, but I'm getting the following issue: 'No such file or directory': /path/to/my/bin/./mybin. Does anyone know what I'am doing wrong? Thank you in advance

   import subprocess
   subprocess.Popen("/path/to/my/bin/./mybin")

Which path is it, `/path/to/my/bin/./mybin` or `/path/to/my/bin/.mybin` ? – khelwood Oct 30 '19 at 09:27
@khelwood ./mybin – Napoleone Capasso Oct 30 '19 at 09:28

Why do you have the single dot there? Seems completely pointless. Change it to this instead: `/path/to/my/bin/mybin` – klutt Oct 30 '19 at 09:29

The only reason I can think of is that the file simply does not exist. – klutt Oct 30 '19 at 09:32

`subprocess.Popen("/path/to/my/bin/mybin")` or `subprocess.Popen("./mybin")`. You could also just use `subprocess.run` with the same argument, you don't need Popen here. – Boris Oct 30 '19 at 09:32
