Python

Switching up: diary.py - Why am I getting this comments on the console?

My question is when I start ./dairy.py it doesn't give me a clean console options that should b option 'a' and 'w'. It returns a long text explaining what the values are going to be like. Any idea? Is this a bug in my code? Here is what I've done:

    #!/usr/bin/env python3

    from collections import OrderedDict
    import datetime

    from peewee import *

    db = SqliteDatabase('diary.db')


    class Entry(Model):
        content = TextField()
        timestamp = DateTimeField(default=datetime.datetime.now)

        class Meta:
            database = db


    def initialize():
        db.connect()
        db.create_tables([Entry], safe="True")

    def menu_loop():
        """nothing yet"""
        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().strip()

            if choice in menu:
                 menu[choice]()

    def add_entry():
        """nothing yet """



    def view_entries():
        """nothing yet """


    def delete_entry(entry):
        """nothing yet """

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

    if __name__ == '__main__':
        initialize()
        menu_loop()

It would help to read your code if you wrapped your code example in a <code>```python<code> ... <code>```<code> as mentioned in the Markdown Cheatsheet. Thanks!

The issue is with your menu definition. The second value of the tuple is expected to be a function, not a string. That is, remove the single quotes wrapping the function names:

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

Trying to evaluate the code 'add_entry'.__doc__ results in a long output string instead of the doc string of the specific function:

In [116]: 'add_entry'.__doc__
Out[116]: "str(object='') -> string\n\nReturn a nice string representation of the object.\nIf the argument is a string, the return value is the same object."

Verses doing the same on the function, yeids the doc string:

In [117]: def add_entry():
   .....:         """nothing yet """
   .....:     

In [118]: add_entry.__doc__
Out[118]: 'nothing yet '

Thanks for the help. I couldn't see what the problem was.
