Python 2 died 998 days ago on 1/1/2020 so please stick with Python 3.

In Examples/User Interface/Calculator.py the button_tapped() function gets the values of label1 and label2.

For your code, you will need to use int(sender.superview['label1']) to get an integer.

+1 @JonB Ideally, actions should be super simple and run quickly. Move complexity to other parts of your code.

state is a weak name because it does not make clear what it is the state of.

is_playing would be a more self-documenting name.

Cool! A nice opportunity for itertools.cycle()...

from itertools import cycle

import ui

button_image = cycle(ui.Image.named(name) for name in ('iob:pause_32','iob:play_32'))


def button_action(sender):
    sender.image = next(button_image)


ui.Button(action=button_action, bg_color='lightgray', image=next(button_image)).present()

sender.image # No space and lowercase i

What does this have to do with https://omz-software.com/pythonista ?

Agreed. If a URL starts with http:// or https:// then it will open in your browser. If a URL starts with pythonista3:// it should open in Pythonista.

Pyto bundles colorama...

• https://github.com/tartley/colorama#colored-output

try:
    xyz
except:
    pass

is a dangerous construction in Python… https://realpython.com/the-most-diabolical-python-antipattern

try:
    xyz
except Exception as e:
    print(repr(e))

might be safer and more enlightening.

return [ key for key in pkg_data['releases'].keys() if pkg_data['releases'][key] ]
# -->
return [key for key, value in pkg_data['releases'].items() if value]

https://pyto.app is the best upgrade path that I know of for Pythonista users.
