Assuming you re on a Unix-like platform  so that ps -A exists     gt  gt  gt  import subprocess  signal  gt  gt  gt  import os  gt  gt  gt  p   subprocess Popen   ps    -A    stdout subprocess PIPE   gt  gt  gt  out  err   p communicate     gives you ps -A s output in the out variable  a string    You can break it down into lines and loop on them       gt  gt  gt  for line in out splitlines          if  iChat  in line          pid   int line split None  1  0           os kill pid  signal SIGKILL          you could avoid importing signal  and use 9 instead of signal SIGKILL  but I just don t particularly like that style  so I d rather used the named constant this way    Of course you could do much more sophisticated processing on these lines  but this mimics what you re doing in shell   If what you re after is avoiding ps  that s hard to do across different Unix-like systems  ps is their common API to get a process list  in a sense    But if you have a specific Unix-like system in mind  only  not requiring any cross-platform portability   it may be possible  in particular  on Linux  the  proc pseudo-filesystem is very helpful   But you ll need to clarify your exact requirements before we can help on this latter part

If you have killall   os system  killall -9 iChat      Or   os system  ps -C iChat -o pid  xargs kill -9

this worked for me in windows 7  import subprocess subprocess call  taskkill  IM geckodriver exe

User · Answer

you can use WMI module to do this on windows  though it s a lot clunkier than you unix folks are used to  import WMI takes a long time and there s intermediate pain to get at the process

The below code will kill all iChat oriented programs   p   subprocess Popen   pgrep    -l     iChat    stdout subprocess PIPE  out  err   p communicate    for line in out splitlines                line   bytes decode line      pid   int line split None  1  0       os kill pid  signal SIGKILL

You can use pkill  lt process name gt  in a unix system to kill process by name   Then the python code will be    gt  gt  gt  import os  gt  gt  gt  process name iChat  gt  gt  gt  os system  pkill   process name

In the same style as Giampaolo Rodol    answer but as one liner  case insensitive and without having to match the whole process name  in windows you would have to include the  exe suffix   x kill   for x in psutil process iter   if  ichat  in x name   lower

The Alex Martelli answer won t work in Python 3 because out will be a bytes object and thus result in a TypeError  a bytes-like object is required  not  str  when testing if  iChat  in line     Quoting from subprocess documentation      communicate   returns a tuple  stdout data  stderr data   The data will be strings if streams were opened in text mode  otherwise  bytes    For Python 3  this is solved by adding the text True     Python 3 7  or universal newlines True argument to the Popen constructor  out will then be returned as a string object   import subprocess  signal import os  p   subprocess Popen   ps    -A    stdout subprocess PIPE  text True  out  err   p communicate    for line in out splitlines        if  iChat  in line          pid   int line split None  1  0               os kill pid  signal SIGKILL    Alternatively  you can create a string using the decode   method of bytes   import subprocess  signal import os  p   subprocess Popen   ps    -A    stdout subprocess PIPE  out  err   p communicate    for line in out splitlines        if  iChat  in line decode  utf-8            pid   int line split None  1  0               os kill pid  signal SIGKILL

psutil can find process by name and kill it   import psutil  PROCNAME    python exe   for proc in psutil process iter          check whether the process name matches     if proc name      PROCNAME          proc kill

You can try this  but before you need to install psutil using sudo pip install psutil  import psutil for proc in psutil process iter attrs   pid    name         if  ichat  in proc info  name            proc kill
