I want to get the process name, given it's pid in python. Is there any direct method in python?

In this quick article, we've explored how to get the name and the command line of a given PID in the Linux command line. The ps -p <PID> command is pretty straightforward to get the process information of a PID. Alternatively, we can also access the special /proc/PID directory to retrieve process information.
With Linux, the info is in the /proc filesystem. To get the command line for process id 9999, read the file /proc/9999/cmdline . And to get the process name for process id 9999, read the file /proc/9999/comm .
wait() return output # This is the function you can use def isThisRunning( process_name ): output = findThisProcess( process_name ) if re.search('path/of/process'+process_name, output) is None: return False else: return True # Example of how to use if isThisRunning('some_process') == False: print("Not running") else: ...
The psutil package makes this very easy.
import psutil
process = psutil.Process(pid)
process_name = process.name()
