python start process and get pid

Download this code from https://codegive.com In Python, the subprocess module provides a way to spawn new processes, interact with their input/output/error pipes, and obtain their process ID (PID). This tutorial will guide you through the process of starting a new process and retrieving its PID using Python. First, import the subprocess module, which provides the necessary functions for working with external processes. Use the subprocess.Popen class to start a new process. The basic syntax is as follows: Replace "command", "arg1", "arg2", etc., with the actual command and its arguments you want to execute. Here's an example that starts the ls command to list files in the current directory: To obtain the PID of the newly created process, access the pid attribute of the Popen object: Putting it all together: Here's a complete example that prompts the user for a command, starts the process, and prints its PID: In this example, the split() method is used to convert the user-entered command string into a list of command and arguments. Remember to handle exceptions, such as subprocess.CalledProcessError that may occur if the command execution fails. That's it! You now have a basic understanding of starting a process and retrieving its PID using Python's subprocess module. Feel free to explore additional features of the subprocess module for more advanced process management tasks. ChatGPT
