How do I get the path and name of the file that is currently executing

Question

I have scripts calling other script files but I need to get the filepath of the file that is currently running within the process    For example  let s say I have three files  Using execfile    script 1 py calls script 2 py   In turn  script 2 py calls script 3 py     How can I get the file name and path of script 3 py  from code within script 3 py  without having to pass that information as arguments from script 2 py    Executing os getcwd   returns the original starting script s filepath not the current file s

Since Python 3 is fairly mainstream  I wanted to include a pathlib answer  as I believe that it is probably now a better tool for accessing file and path information   from pathlib import Path  current file  Path   Path   file    resolve     If you are seeking the directory of the current file  it is as easy as adding  parent to the Path   statement   current path  Path   Path   file    parent resolve

Most of these answers were written in Python version 2 x or earlier  In Python 3 x the syntax for the print function has changed to require parentheses  i e  print     So  this earlier high score answer from user13993 in Python 2 x   import inspect  os print inspect getfile inspect currentframe      script filename  usually with path  print os path dirname os path abspath inspect getfile inspect currentframe        script directory   Becomes in Python 3 x   import inspect  os print inspect getfile inspect currentframe       script filename  usually with path  print os path dirname os path abspath inspect getfile inspect currentframe          script directory

I think this is cleaner   import inspect print inspect stack   0  1    and gets the same information as   print inspect getfile inspect currentframe      Where  0  is the current frame in the stack  top of stack  and  1  is for the file name  increase to go backwards in the stack i e   print inspect stack   1  1    would be the file name of the script that called the current frame  Also  using  -1  will get you to the bottom of the stack  the original calling script

The suggestions marked as best are all true if your script consists of only one file    If you want to find out the name of the executable  i e  the root file passed to the python interpreter for the current program  from a file that may be imported as a module  you need to do this  let s assume this is in a file named foo py    import inspect  print inspect stack   -1  1   Because the last thing   -1   on the stack is the first thing that went into it  stacks are LIFO FILO data structures    Then in file bar py if you import foo it ll print bar py  rather than foo py  which would be the value of all of these      file   inspect getfile inspect currentframe    inspect stack   0  1

I used the approach with   file   os path abspath   file    but there is a little trick  it returns the  py file  when the code is run the first time   next runs give the name of   pyc file so I stayed with  inspect getfile inspect currentframe    or sys  getframe   f code co filename

The   file   attribute works for both the file containing the main execution code as well as imported modules   See https   web archive org web 20090918095828 http   pyref infogami com   file

User · Answer

It s not entirely clear what you mean by  the filepath of the file that is currently running within the process   sys argv 0  usually contains the location of the script that was invoked by the Python interpreter  Check the sys documentation for more details   As  Tim and  Pat Notz have pointed out  the   file   attribute provides access to     the file from which the module was   loaded  if it was loaded from a file

import os os path dirname os path abspath   file       No need for inspect or any other library   This worked for me when I had to import a script  from a different directory then the executed script   that used a configuration file residing in the same folder as the imported script
