This is a simple cheat sheet, only containing stuff I've used before. See https://psutil.readthedocs.io/en/latest/ for full docs
{{{c
import psutil

print(psutil.pids()) # get list of pids

# this is the preferred method for iterating over pids
# (i.e. don't iterate over the list returned by psutil.pids() )
for proc in psutil.process_iter():
  # proc is a psutil.Process
  # (note pid is an attribute, not a method)
  proc.pid
  proc.name()
  proc.cmdline()
