How to execute a program in python script directory

[scaldo]

I am just starting out on Python and trying to make a simple interface as practice. Right now I can execute a program through the os.popen command. However, I have to specify the directory where the program is located. For example, say:

os.popen("c:\pr ogram^files\pro gramb.py")

Is there any way I can tell Python to assume the default directory is wherever the interface script is ran from? So say I have a folder and inside are all my python files. So when I click on a button to open programb, the script knows to only search in that folder. I am trying to make everything self-contained so the folder may be in different places in the directory (could be C:\, desktop, c:\program files, etc.). By the way, Python is an AWESOME language, I can't believe I didn't get into this earlier in my life.

to open a file for reading:

 
file = open("c:\path\to\file.txt", 'r')  # Windows
file = open("/home/user/file.txt", 'r')  # for Linux
for line in file:
    print line,
file.close()
 
 

This will print out each line of "file".

Thanks again. Is there any way I can open the file using another program, but it's called by the Python script? For example, if I want to use my Python script to open a text file using gedit or a pdf file using document viewer. Because ultimately I want to leave the terminal and have as much "GUI" as possible. Is there a generic way to open a file that may be handled by another program (such as, again, gedit for text or document viewer for pdf). Nevertheless, I really do appreciate the help, it's been a tremendous boost to what I would otherwise be in a big headache.

Sorry, I haven't crossed that bridge yet. Try asking on the python tutor mailing list.

I'm not sure I completely understand your question, but would it work to use an operating system specific command through the os.system function?

import os
os.system("'C:/myprogram' 'C:/myfile.txt'")
