You can call GetConsoleWindow [1] and then SetForegroundWindow [2].

    import os
    import sys

    try:
        import tkinter
        from tkinter import filedialog
    except ImportError:
        import Tkinter as tkinter
        import tkFileDialog as filedialog
        input = raw_input

    if sys.platform == 'win32':
        import ctypes

        kernel32 = ctypes.WinDLL('kernel32')
        user32 = ctypes.WinDLL('user32')

        def setfgwin():
            hcon = kernel32.GetConsoleWindow()
            if hcon and user32.SetForegroundWindow(hcon):
                return True
            return False

    def get_filename():
        filename = filedialog.askopenfilename()
        setfgwin()
        return os.path.normpath(filename)

    if __name__ == '__main__':
        root = tkinter.Tk()
        root.withdraw()
        filename = get_filename()
        print('filename: %s' % filename)
        input('press enter...')
