If you want to open whatever path the user chose in their preferred editor (or the system’s default for text files), avoid hardcoding gedit and use a cross-platform launcher. This works with any runtime path stored in a variable:

import os, sys, subprocess

def open_in_editor(path):
    if not os.path.exists(path):
        raise FileNotFoundError(path)
    if sys.platform.startswith("win"):
        os.startfile(path)  # uses the associated editor
    elif sys.platform == "darwin":
        subprocess.Popen(["open", path])  # macOS
    else:
        editor = os.environ.get("EDITOR") or os.environ.get("VISUAL")
        if editor:
            subprocess.Popen([editor, path])
        else:
            subprocess.Popen(["xdg-open", path])  # desktop default on Linux

well, there is os.system,
so you can do os.system("gedit file.txt") ,
and you can also make it detect windows, and so it will do os.system("notepad file.txt") , but another way is to make a GUI text editor in pygtk and open that, but that takes more work.

A good solution is

import webbrowser
webbrowser.open("file.txt")

On my system, it opens the file with gedit.

Thanks for the solution ..
actually ... the output of my application is stored in a file which is given by the user during runtime
so the path of the file is stored in a variable.
now i want to open the file using the variable which stores the complete path of the file ..

According to the above mentioned solutions .. that is possible if the file name is known to us before ...

So,how can i do it now ?

It's very simple

myVariable = "file.txt"
webbrowser.open(myVariable)
Member Avatar for vskumar19

In windows that webbrowser command openned file I put in argument in my Notepad2, configured text editor.

Thanks, I was suffering for same missing as I wanted to have program to generate answers in fast speed and then open them in text editor. That is better solution than letting the results to scroll too fast to read.

Of course it is easy to open simple tk window with ScrolledText widget, but anyway..

Thanks, Griboulis!

It may depend on your version of python. For python 2.6 on my gnome desktop, the webbrowser module opens text files with gedit. Otherwise, you can use

import subprocess as sp
myVariable = "file.txt"
sp.Popen(["gedit", myVariable])

Or perhaps you could do this:

import os
var = 'test.txt'
os.system('gedit '+var)
