EOFerror file while using control D

I run into an EOFerror with tghis code. I caught it with two Try-Except blocks. That however creates an infinite loop. I have researched a bit further so control Z seems to be the proper solution instead of control D. But this also hardly satisfactory because it provides a strange transation to: if input("Save entry Y/n: ").lower() != 'n':

it actually gives you the control Z and you have to enter it to make the transition. Using control z seems an inferior solution.

db = SqliteDatabase('diary.db')

class Entry(Model): content = TextField() timestamp = DateTimeField(default=datetime.datetime.now) # not adding () after now ensures the function is called everytime an antry is made # as supposed to just when running the script

class Meta:
    database = db

def initialize(): '''create database and table if they don't exist''' db.connect() db.create_tables([Entry], safe=True)

def menu_loop(): '''show menu''' choice = None

while choice != 'q':
    print("Enter 'q' to quit")
    for key, value in menu.items():
        print("{}) {}".format(key, value.__doc__))
        choice = input("Action: ").lower()
    except EOFError:
    if choice in menu:

def add_entry(): """add entry in the diary""" print("Add your entry. Press ctrl+d when finished") data = sys.stdin.read().strip()

if data:
        if input("Save entry Y/n: ").lower() != 'n':
            print("Saved succesfully!")
    except EOFError:
        print("Save aborted")

def view_entries(): '''show the entries existing in the diary'''

def delete_entry(): '''Delete an existing entry in the diary'''

menu = OrderedDict([ ('a', add_entry), ('v', view_entries) ])

if name == 'main': initialize() menu_loop()
