Open Another Tkinter Program From A Main File

I have try this in my main program from tkinter import * import tkinter.filedialog import os root = Tk() def open(): PathPy = tkinter.filedialog.askopenfilename(title='Open a f

Solution 1:

Two additions to your code may give the expected result.

os.system expects a "command" for the operating system:

Execute the command (a string) in a subshell.

like python3 myscript.py.

However, since you are using a custom python programming environment, pass the path of the EduPython's python.exe to os.system:

from tkinter import *
import tkinter.filedialog
import os
import sys

root = Tk()
pyexec = sys.executable

defopen():
    PathPy = tkinter.filedialog.askopenfilename(title="Open a file",filetypes=[('PYTHON file','.py')])
    os.system('%s %s' % (pyexec, PathPy))

B = Button(root, text="Open a file", command=open).pack()
root.mainloop()

Second, add the last line root2.mainloop() to your second script to make the second Tk window appear.

Hope this helps.

Solution 2:

As you are trying to execute a python file, use execfile(file). But if all you want is a dialog, then use the Toplevel class.

To keep both windows running, use different threads. It's very easy to do in python.
