The Popen class handles the process creation and management. By using this module, developers can handle less common cases. The child program execution will be done in a new process. To execute a child program on Unix/Linux, the class will use the os.execvp() function. To execute a child program in Windows, the class will use the CreateProcess() function.
Now, let's see some useful arguments of subprocess.Popen():

Let's look at each argument:
- args: It can be a sequence of program arguments or a single string. If args is a sequence, the...
