Insert a terminal other than xterm in a Frame of a GUI built in Tkinter

I was able to insert an xterm terminal in a Frame of a Tkinter GUI with the following code:

Frame2 = Frame(master)
Frame2.pack(fill=BOTH, expand=YES)
wid = Frame2.winfo_id()
os.system('xterm -into %d -hold -geometry 300x10 -sb &' % wid)

The question is how can I include, for example, the terminal konsole (or the gnome-terminal). The following code, for example, opens a terminal konsole, but in a separate window:

wid = Frame2.winfo_id()
os.system('konsole -geometry 300x10 %d &' % wid)
