The expression 

choice == 'Entry' or 'entry'

is evaluated by Python as

(choice == 'Entry') or 'entry'

All strings but "" are True in a boolean context, so this has the same 
effect as

(choice == 'Entry') or True

and is always True. Possible fixes:

if choice == "Entry" or choice == "entry":
if choice in ("Entry", "entry"):
if choice.casefold() == "entry".casefold(): # will accept ENTRY, eNtRy etc.
