Trouble with place_forget() - python-3.x

Question

I have been trying to get .place_forget() to work in my test application but I am having some difficulty.
I am trying to get the widgets in "def select_1:" to show when R1 "Yes" checkbox is checked and then have the widgets not show when the check is removed.
The widgets show when I check the box but will not forget(hide) when it is then unchecked.
Any assistance would be greatly appreciated.

When you want to make a widget disappear and then appear again, you don't actually have to define it and all it's options again.
#=========================== CHECK BUTTON SELECTION ============================
pass_entry = Entry(root, width = 20, textvariable = pass_1, bg='#000000', fg='#B3CDE0')
selection = Label(root, text='Enter OS Password:', bg='#000000', fg='#B3CDE0')
def select_1():
if var1.get()==1:
pass_entry.place(x=250,y=275)
pass_entry.focus_set()
selection.place(x=140,y=275)
elif var1.get()==0:
pass_entry.place_forget()
selection.place_forget()
else:
return
Notice how pass_entry and selection are defined outside of the function and only placed inside the function.
What's a bit confusing though is why you're using two separate buttons for "yes" and "no" if checking them doesn't automatically uncheck the other one (i assume that's the purpose of the two buttons).
If that's what you want to do, you should use the Radiobutton widget instead. Notice how both of them affect the same variable and each of them have one value.
#=============================== RADIO BUTTONS =================================
R1 = Radiobutton(root, text="Yes", variable = var1, value = 1, height=1, width = 15, activebackground = '#000000', bg='#000000', fg='#B3CDE0', command=select_1)
R1.place(x=350,y=250)
R2 = Radiobutton(root, text="No", variable = var1, value = 0, height=1, width = 15, activebackground = '#000000', bg='#000000', fg='#B3CDE0', command=select_1)
R2.place(x=350,y=275)
I also tidied up the other options a bit too, you had some random spacing in there.
