title: Using Python subprocess to keep track of files created by the executable
body: <p>I am new to python and to Redhat linux. I am using the subprocess module to execute another C program that creates a file. I am able to capture the exit code from the C program. But is there any way I can also make python track and display the name of the file created by the C program?</p>
  
  <p>Note: I cannot modify the C program. The C program creates output files with timestamps and many instances of it could be running in parallel. I only want to capture the files created by the instance run by python.
  Is there any other way to do this if not the subprocess module?</p>
