What is the difference if I don't use stdout=subprocess.PIPE in subprocess.Popen()?

Question

I recently noted in Python the subprocess.Popen() has an argument:

stdout=None(default)

I also saw people using stdout=subproc

Answer 1

• stdout=None means that subprocess prints to whatever place your script prints
• stdout=PIPE means that subprocess' stdout is redirected to a pipe that you should read e.g., using process.communicate() to read all at once or using process.stdout object to read via a file/iterator interfaces
