It would be nice if the Black formatter could be added natively to Pythonista.
For those who don't know about Black: this is a code formatter that makes your code PEP8 compatible and very consistent: highly recommended. See https://black.readthedocs.io/en/stable/ for details.

Any plans to support Pandas?

And PyTo is open source, so even if the developer is not anymore supporting the product (like seems the case with Pythonista) others can continue the product (at least in theory).

Thanks for this great idea.
I have renamed your decorator to getter_setter, to make the purpose of it more clear.

Thus we define a decorator function:

def getter_setter(func):
    return property(func, func)

and then we can redo the example as:

class Example:

@getter_setter
def my_property(self, *value):
    if value:
        self._my_property = value[0]
    else:
        return self._my_property

or EAFP style:

class Example:

    @getter_setter
    def my_property(self, *value):
        try:
            self._my_property = value[0]
        except IndexError:
            return self._my_property

Optionally, we could define two more decorators for getter only and setter only properties:

def getter(func):
    def raise_attribute_error(*args):
        raise AttributeError("can't set attribute")
    return property(func, raise_attribute_error)
    

def setter(func):
    def raise_attribute_error(*args):
        raise AttributeError("can't get attribute")
    return property(raise_attribute_error, func)

Here is an example of a Circle class demonstrating the three decorators.
radius can be used to get the radius and set the radius (thus updating the _area attribute)
area can be used to get the area only. Setting will raise an error.
diameter can only be used to set the radius. You can’t get it.

Here is an implementation with getter_setter only:

import math


class Circle:
    def __init__(self, radius):
        self.radius = radius
        
    @getter_setter
    def radius(self, *value):
        if value:
            self._radius = value[0]
            self._area = math.pi * self._radius ** 2
        else:
            return self._radius
            
    @getter_setter
    def area(self, *value):
        if value:
            raise AttributeError("can't set attribute")
        else:
            return self._area
            
    @getter_setter
    def diameter(self, *value):
        if value:
            self.radius = value[0] / 2
        else:
            raise AttributeError("can't get attribute")

And if we use getter and setter as well:

import math


class Circle:
    def __init__(self, radius):
        self.radius = radius
        
    @getter_setter
    def radius(self, *value):
        if value:
            self._radius = value[0]
            self._area = math.pi * self._radius ** 2
        else:
            return self._radius
            
    @getter
    def area(self):
        return self._area
            
    @setter
    def diameter(self, value):
        self.radius = value / 2

I just found out that if change the file format from PNG to BMP speeds up the animation significantly: from 4 to > 16 fps.

Dataclasses

Super. That works!

I have noticed that stash install a package in site-packages-3, but I would like it to be installed in site-packages.
How can I force stash pip install to install in site-packages.
BTW. I am running stash v0.7.2

Is there a possibility to set the background colour of the console?
For the foreground (text), there's console.set_color, but I can't seem to find a function to set the background.

With the new Pythonista 3.3 (thanks Ole!), I ran into a problem with the Synchronator script, that I use regularly.
The scripts hard codes the colour to be written text with as (0,0,0). As a solution I have just disabled the colour setting at all, so I can at least see what's going.
But it would be nice if I could check the dark/light mode setting from Python.
Or, maybe better yet, get the current theme colours.

Would it be possible to force the console output to another theme?

I just noticed that under Pythonista, it is not required to say
import os,
import sys or
import shutil.
That seems fine ... until you run the same script on another platform.

So, be careful to import these modules explicitily in order to avoid problems when porting to another platform.

@cvp
This absolutely briliant!

One of the mainstream UI packages (tkinter, PyQt, wxPython) please. Please!

@brumm
Thanks.That's very useful.

As much as I like Pythonista, we have to face the fact that there's no more development. Fortunately there's a very active, open source, Python environment for iOS/iPadOS called PyTo. And they have just released Python 3.8.
Unfortunately I can't find a forum, like this one for that app. Is anyone aware of a user group or similar for PyTo?

And PyTo is open source, so even if the developer is not anymore supporting the product (like seems the case with Pythonista) others can continue the product (at least in theory).
