This certainly wasn't obvious from what I could find on the internet.
Now I see an application for Lambda
I should point out you can use a def if you prefer:
def second():
main=Toplevel(root)
ofield=Text(main, height=15, width=15)
ofield.pack()
B3=Button(main, text='exit', command=main.destroy)
B3.pack()
def genFwrapper(widget = ofield): return genF(widget)
B4=Button(main, text='fill text', command=genFwrapper)
B4.pack()
The lambda just saves a line.
