I use both Carnets and Pyto, and love both of them.
But I am not an advanced user so they help me learn Jupiter Notebooks (Carnets)
And both can run Pandas, which is superb.
Pyto is updated regularly and runs 3.8 version of Python

I Am Using Pythonista On My iPad Pro And I Have No Issues At All, It Works Fine.

I love Pythonista, and learned a lot of Python on the go..
Apart from pythonista, i am enjoying Pyto (with Python3.8) and Carnets (Like Jupyter Notebooks), especially, as both of these work with Pandas.

Thank you @cvp for all your help and @Phuket2 for filtering code.
I have put up the fully working version below.
I use this to order a lot of books for our bookstore.
I have the csv data file with a few thousand records of book title and book author.

Thank You Very Much For The Prompt Reply @cvp !
I can figure it out now. :)

@foundjem
No, it does not.
So I use 'carnets' app which has support of most modules including pandas.
carnets is jupyter notebooks on iOS, it is great and free.. a little quirky, though :)

Hi Friends,
I am trying to use a filter which must update the data source continuously in my tableview.
I figured it out for ui.LitsDataSource but i have wasted a couple of days trying to do the same with
MyTableViewDataSource method.
This filter was shown by a kind friend @Phuket2 about 2 years ago.
It was must a very simple mistake i am making, tried using reload() method too.
Here is my program, forgive the sloppiness..
Thank you.

Love Pythonista And Love Reddit.
I think the biggest advantage in moving to Reddit would be getting a more intelligent search, searching in this forum is not good.
I am no expert but i see no downside to shifting to Reddit.

HI @sulcud,
Mindnotes app, looks interesting,
could you please put up the english version,
when you are free.
Thank you

@ccc
Beauty !

Glad To See The Forum Back..
Lot Of Catching Up To Do ! :)
Thank You @omz and @JonB

@Phuket2 ,
Thank you very much for the tip.
I would also like to thank you for your old post on the same topic at
https://forum.omz-software.com/topic/3401/share-using-draw_snapshot-method
which i saw after i posted this thread.
Sometimes searching is very difficult in this forum. :)
Take Care

@cvp ,
Thank You Very Much, Exactly What I Wanted.. :)

HI,
I am sure this is a basic question..
i want the simplest way to save the puzzle generated on the console to be saved as an image.
I tried reading through ImageContext, Image, ctx etc but failed to understand.
Please help..

For eg. let's say i want to save this display as an image..

# save display
import ui

w,h = ui.get_screen_size()
view = ui.View(name = 'Grid', bg_color=1)
view.add_subview(ui.View(name='left', frame=(0,0,w/3,h/5), bg_color='blue'))
view.add_subview(ui.View(name='right', frame=(w*2/3,0,w/3,h/5), bg_color='red'))
view.present('sheet')

Thank you very much @ccc for your constant support and prompt help.

Yes, I found some old file, i had named matplotlib.py ,
I have renamed it and now everything works fine.
Silly mistake on my part when i started with pythonista.

Hi,
I often get "cannot import name 'pyplot' error"
when i try to import matplotlib

As a work around, I go to Examples folder and run any plotting example, then it works,
after which i can import matplotlib normally.

The error states something about "frozen importlib._bootstrap"
How can i avoid this error, in pythonista 3

Thank you.

# Histogram
# Basic plot
import numpy as np
import matplotlib.pyplot as plt
height = [3, 12, 5, 18, 45]
bars = ('A', 'B', 'C', 'D', 'E')
y_pos = np.arange(len(bars))
plt.bar(y_pos, height, color=(0.2, 0.4, 0.6, 0.6))
 
# Custom Axis title
plt.xlabel('X Axis Title', fontweight='bold', color = 'red', fontsize='17', horizontalalignment='center')
plt.show()```

Hope this helps..

# sets date time picker
# you can get details of different parameters from strftime.org
import datetime, ui
date_picker = ui.DatePicker(bg_color=1)
date_picker.mode = ui.DATE_PICKER_MODE_DATE_AND_TIME
date_picker.date = datetime.datetime.strptime('01/03/1958-07:00:PM', '%d/%m/%Y-%I:%M:%p')
date_picker.present()

Hi,
I wrote a small utility for this.. hope you find it useful.

@cvp Totally Agree!!
