[PySimpleGUI] Tutorial - Name, Address, Phone GUI

[jfong]

A change to how dictionaries work.

You no longer need to specify when creating the form that it should return a dictionary. If ANY element in the form that has a key specified will cause all of the elements to return a dictionary entry.

If one element has a key and others do not, then the other fields are simply numbered starting at 0. That number is used as the key for the field.

For example:

import PySimpleGUI as sg

layout = [
          [sg.Text('Please enter your Name, Address, Phone')],
          [sg.Text('Name', size=(15, 1)), sg.InputText('1')],
          [sg.Text('Address', size=(15, 1)), sg.InputText('2', key='address')],
          [sg.Text('Phone', size=(15, 1)), sg.InputText('3', key='phone')],
          [sg.Submit(), sg.Cancel()]
         ]

button, values = form.LayoutAndRead(layout)

sg.MsgBox(button, values, values[0], values['address'], values['phone'])

Two of the Input fields have keys but the first one doesn't. That means that the first field will be returned with a dictionary key of 0.

Inspired by your new change, allow me to push it one step further.

If none of the elements has a key, then all fields are simply numbered starting at 0.

This means that values is always returned as a dictionary, get rid of the confusion between list and dictionary. With this change, for those already written scripts which treat values as a list, the only required modification is where items were accessed through unpack, such as:

name, address, phone = values

modified to

name, address, phone = values.values()

If item was accessed by index, then no change at all.

name = values[0]

it's valid on both list and dictionary.
