How to get path to file for python executable

Question

I'm trying to get path in python to open and write in text document by already exist path directory C:\ProgramData\myFolder\doc.txt, no need to create it, but make it work with python executable on user computer. For example if this way I got folder there:

   mypath = os.path.join(os.getenv('programdata'), 'myFolder')

and then if I want write:

  data = open (r'C:\ProgramData\myFolder\doc.txt', 'w')

or open it:

    with open(r'C:\ProgramData\myFolder\doc.txt') as my_file:

Not sure if it is correct:

   programPath = os.path.dirname(os.path.abspath(__file__))

   dataPath = os.path.join(programPath, r'C:\ProgramData\myFolder\doc.txt')

and to use it for example:

   with open(dataPath) as my_file:

i think you want `dataPath = os.path.join(programPath, r'myFolder\doc.txt')` ? `__file__` will will you path to your script py file — Skycc, Dec 07 '16 at 03:45
@Skycc hello, I tried but in this case it does not writes `data = open (dataPath, 'w')` if I use it this way for example — , Dec 07 '16 at 04:03
not clear on what you want, i guess its because the dir is not there, `dataPath = os.path.join(os.getenv('programdata'), 'myFolder');os.makedirs(dataPath);with open(os.path.join(dataPath, 'doc.txt'), 'w') as my_file: ` — Skycc, Dec 07 '16 at 04:09

I would start by figuring out a standard place to put the file. On Windows, the USERPROFILE environment variable is a good start, while on Linux/Mac machines, you can rely on HOME.

from sys import platform
import os
if platform.startswith('linux') or platform == 'darwin': 
    # linux or mac
    user_profile = os.environ['HOME']
elif platform == 'win32': 
    # windows
    user_profile = os.environ['USERPROFILE']
else:
    user_profile = os.path.abspath(os.path.dirname(__file__))
filename = os.path.join(user_profile, 'doc.txt')
with open(filename, 'w') as f:
    # opening with the 'w' (write) option will create
    # the file if it does not already exists
    f.write('whatever you need to change about this file')

For Python 3.x, we can

import shutil
shutil.which("python")

In fact, shutil.which can find any executable, rather than just python.
