Introduction to psutils.get_process_list()

The psutils.get_process_list() function is a powerful tool for any programmer working with Python. It is a function from the psutils module that allows you to access information about the running processes on your system.

With psutils.get_process_list(), you can get a list of all the running processes on your machine. This function returns a list of psutil.Process objects, each of which contains information about an individual process.

To use psutils.get_process_list(), you first need to import the psutil module:

import psutil

Once you've imported the psutil module, you can call psutils.get_process_list() to get a list of all the running processes on your machine. Here's an example:

import psutil

processes = psutil.get_process_list()

for process in processes:
    print(process.name())

In this example, we get a list of all the running processes on the machine and then print the name of each process.

Some of the information you can get with psutils.get_process_list()

Using psutils.get_process_list(), you can access a wide variety of information about the running processes on your system. Here are just a few examples:

• Process ID (pid)
• Parent process ID (ppid)
• Name of the process (name)
• Path to the executable file of the process (exe)
• The command-line arguments passed to the process (cmdline)
• The username of the user running the process (username)
• The CPU percentage used by the process (cpu_percent)
• The memory usage of the process (memory_info)

For example, if you wanted to get the process ID and memory usage of each running process on your system, you could do the following:

import psutil

processes = psutil.get_process_list()

for process in processes:
    pid = process.pid
    mem_info = process.memory_info()
    print("Process ID: {}, Memory Usage: {}".format(pid, mem_info.rss))

In this example, we get the pid and memory_info of each process and print them out.

Conclusion

The psutils.get_process_list() function is a powerful tool for any programmer working with Python. It allows you to access a wide variety of information about the running processes on your system. With this information, you can write programs and scripts that monitor and manage the processes on your machine.
