How to ask a good question

zrzka

@Matteo update to 3.2 & use 3.6 as default interpreter (the error is about f strings).

dgelessus

@zrzka If I remember correctly, @Matteo said in another thread that he isn't able to update, because of the Python 2 matplotlib crashes in 3.2.

If the f-strings are the only issue, you can probably translate them to format calls by hand, which work on any Python version since 2.6 or so. For example, f"{url} does not point to the Pythonista forum" would become "{} does not point to the Pythonista forum".format(url).

@zrzka Hi, ok it is a problem related to version of Pythonista, but @dgelessus is right: for now I'm happy with 3.1 version so no need to upgrade.
I understand that there is a solution for my problem without upgrade. Can you (@zrzka , @dgelessus or someone else) kindly show me how can I modify the rest of the script in order to not obtain errors related to f-string? In other words can you provide a modified version of the script working with python 2.7.12?

Thank you for help
Regards

@Matteo An approach to enable fstrings in 3.1:

In stash:
pip install tokenize_rt

Then, Download future_fstrings.py, and install into site-packages-3.

Create usercustomize.py in site-packages-3, which includes

import future_fstrings
future_fstrings.register()

(Iirc, pythonista_startup doesnt get executed by the extension, but usercustomize.py does)

Finally, add

# -*- coding: future_fstrings -*-

to the top of any file where you want fstrings enabled, such as zrzka's script.

Hi @JonB, thank you for suggestion! I will try your procedure.

@enceladus thank you for showing me an other way to do what I ask: when I will be able to use @zrzka script with python 2.7.12 by trying to copy the code here (as you suggest) in clipboard, I will try also the @omz script!

Regards

Matteo

Hi @JonB , your procedure works very well! @zrzka script works very well in Pythonista version I use, Thank you guys!

Guys, below in the snippet is a func 'pythonista_info'. I am pretty sure @JonB wrote this function a long time ago. It still seems to work ok. My wapper to copy it to the clipboard is not so nice(user friendly). But a refined version of what is below could be used as a wrench item to get details about the env when you are posting to the forum. I didn't attempt to make a nice version of it. I think others would do a better job than me.

This is quite old, so maybe it does need updating...

import clipboard, console
import os, platform, plistlib, scene, sys


def pythonista_info():
    plist = plistlib.readPlist(os.path.abspath(os.path.join
                              (sys.executable, '..', 'Info.plist')))

    ios_ver, _, machine_model = platform.mac_ver()

    return dict(pythonista_ver_str=plist['CFBundleShortVersionString'],
                pythonista_ver_num=plist['CFBundleVersion'],
                ios_ver_str=ios_ver,
                screen_resoultion=scene.get_screen_size(),
                screen_scale=scene.get_screen_scale(),
                machine_architecture=platform.architecture()[0],
                machine_model=machine_model,
                )

if __name__ == '__main__':
    info = pythonista_info()
    str_info = "\n".join(str((k, v)) for k, v in info.items())
    clipboard.set(str_info)
    print(str_info)
    console.hud_alert('Pythonista Env copied to clipboard')

@Phuket2 Immediately integrated in my apps/tools

Regarding the pythonista_info function I posted above. I have since had a few freezes with using it (Pythonista becomes unresponsive) and a hard restart is required.
Ok, I found the original post, its over 2 years old. @ccc , @JonB and @dgelessus all helped out on this post. It would be nice if anyone could see why it would be intermittently freezing now. I can imagine quite a few things have changed in 2 years :). Anyway, it would nice to have it stable or an equivalent for easily getting your devices info, to be able to paste into posts if needed. I realise the dict keys could be better if they are to be used as part of the output.
@cpv, have you had a freeze using it?

cvp

@Phuket2 No freeze but not used a lot...

Phuket2

@cvp , ok thanks. There is something wrong though, if I use it multiple times I can get it to freeze. Hopefully someone will spot the problem

@Phuket2 I've corrected a serious error 😂
