Python Locating the file path

Question

How to tell python for example, I made a program, which opens a specific .scv

In example csv=open('c:\Users\Luka\Desktop\prvi.csv','r')

But when I make an .exe file, that is required to run on all PCs. How can I swap that "Luka" so it works for any PC that has a prvi.csv file on desktop.

Answer 1

import os 
os.path.expanduser(path)

• Sven Marnach: You should substitute "~/Desktop/prvi.csv" for the path to make this answer somewhat more complete.

Answer 2

import os 

1. to get username, use os.environ['username']

2. to construct the path to the file, in case file is on desktop on every machine, use

   csv=open(os.environ['homedrive'] + os.environ['homepath'] + '\\Desktop\\prvi.csv','r')

• Sven Marnach: @LukaMihaldinec: The solution by Uku Loskit is not only much simpler: os.path.expanduser("~/Desktop/prvi.csv"), it also works on Mac OS and on many Linux systems.
• Narraxus: I didn't know ("~/Desktop/prvi.csv") this part :P

Answer 3

check out http://docs.python.org/library/getpass.html

Should be

>>> import getpass
>>> getpass.getuser()

Store the username in a variable and substitute in your path name.
