如何在Tkinter中执行Python程序

Question

I have a simple Tkinter GUI, with one button and when the button is pushed I want it to run another program that I have written in Python.

 def openProgram ():
     #open up MyProgram.py

 MGui = Tk()
 MGui.geometry('450x450')

 mbutton = Button(text = "Go", command = openProgram).pack()

Seems easy enough, maybe I am not searching the correct terms.

Answer 1

You can call functions defined in another file by import ing that file.

reticulator.py:

def main():
    print "reticulating splines..."
    #do stuff here
    print "splines reticulated"

gui.py:

from Tkinter import *
import reticulator

def openProgram():
    #call the `main` function defined in the other file
    reticulator.main()

MGui = Tk()
MGui.geometry('450x450')

mbutton = Button(text = "Go", command = openProgram).pack()
MGui.mainloop()

Answer 2

尝试使用os.system：

import os os.system("MyProgram.py")
