Check if a particular Python script is already running

Question

How can I check, from a Python script, if another specific Python script is running?

def running():
    for q in psutil.process_iter():
        print q
        if q.name() == 'server_class.py':
            return True
    return False

I have tried that but the program is called "python" and not the name of the script.

The python script file will be part of the command line. You can try something along these lines:

def running():

    for q in psutil.process_iter():
        if q.name() == 'python':
            print q.cmdline()
            if len(q.cmdline())>1 and 'server_class.py' in q.cmdline()[1]:
                return True

    return False

I am using in just for the example. You might want to match the full path.
