Thank You @ccc .
You're always there :)
And I'm sure, you can reduce this code by half ! -

Hi Friends,
After a long time, I was writing code in pythonista, to help learn, playing piano notes.
I am sure this may not be the optimal solutiion. But it works, and I am always ready to
learn from the experts here. Thank You!# to learn playing piano keys from phone display # not scaled for ipad import ui import sound import time from random import choice from scripter import script, start_scripter td=1 # default time delay 1 sec # piano keys from A3 to G4# are Available with following names (21 keys) piano_klist = [ "piano:C3", "piano:C3#", "piano:D3", "piano:D3#", "piano:E3", "piano:F3", "piano:F3#", "piano:G3", "piano:G3#", "piano:A3", "piano:A3#", "piano:B3", "piano:C4", "piano:C4#", "piano:D4", "piano:D4#", "piano:E4", "piano:F4", "piano:F4#", "piano:G4", "piano:G4#" ] # to load sound effects for minimum latency for key_name in piano_klist: sound.load_effect(key_name) def slider_action(sender): global td # to set slider value reversed, so that # bpm can go up sliding towards right td = round(((1-sender.value)*1.75)+0.2, 2) bpm=int (60/td) lb.text= str(bpm) + ' BPM' # I put this here hoping it will avoid keyboard popping up # and covering the display area ui.end_editing() # very important to update label with name of music note @script def rnd_note(sender): # set to practice for 12 notes at a time repeat = 12 for note in range(repeat): key_name = choice(piano_klist) time.sleep(td) lb1.text = key_name[6:] sound.play_effect(key_name) yield time.sleep(td) lb1.text = '♫' lb.text = 'Tempo Slider' w,h = ui.get_screen_size() # if in landscape mode if w>h: w,h=h,w gap = 10 v = ui.View(name='Piano Practice', bg_color = 'lightyellow') v.frame = (gap,gap,w,h) start_scripter(v) lb = ui.Label(name = 'mylabel') lb.frame=(gap*2, 10, w-4*gap, 30) lb.background_color='gray' lb.text_color = 'yellow' lb.font = ('Helvetica', 18) lb.text = 'Set Tempo BPM' lb.alignment =1 lb.flex = 'W' slider = ui.Slider() slider.value=0.5 slider.frame=(gap*2,gap+32,w-4*gap,50) slider.background_color='gray' slider.flex = 'W' slider.action = slider_action lb1 = ui.Label(name = 'note') lb1.frame= (gap*2, gap+100, w-4*gap, h-475) lb1.font = ('Helvetica', 150 ) lb1.text_color = 'yellow' lb1.alignment =1 lb1.background_color = 'gray' lb1.text = '♫' lb1.flex = 'W' button = ui.Button(name='start') button.frame = (gap*2, 300, w-4*gap, 40) button.bg_color='yellow' button.border_width=1 button.title='Start' button.font = ('Helvetica', 18) button.flex = 'W' button.action=rnd_note v.add_subview(slider) v.add_subview(lb) v.add_subview(lb1) v.add_subview(button) v.present('sheet')

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.

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.# filtering data with two items per record # example with tableview cells with subtitles # And TableView Delegate method import ui items = [ ['Pretty Woman', 'Julia Roberts'], ['Seven Year Itch', 'Marilyn Monroe'],['Casablanca' , 'Ingrid Bergman'], ['Roman Holiday','Audrey Hepburn'], ['Sound Of Music','Julie Andrews'], ['Love Story','Ali McGraw'], ['You Got Mail','Meg Ryan'], ['Clueless','Alicia Silverstone'], ['Great Gatsby','Mia Farrow'], ['Mask','Cameron Diaz'] ] w,h = ui.get_screen_size() h=h-64 gap = 5 fontsize = 15 if w<750 else int((w / 75) + 16) def reload_data(): tbl.data_source.reload() class MyTableViewDataSource (object): def tableview_cell_for_row(self, tableview, section, row): row_title, row_description = items[row] # 'subtitle'-style cells come with a built-in secondary label cell = ui.TableViewCell('subtitle') cell.text_label.text = row_title cell.text_label.text_color = 'blue' cell.detail_text_label.text = row_description cell.detail_text_label.text_color = 'slateblue' #'#555' return cell def tableview_number_of_rows(self, tableview, section): return len(items) class MyTableViewDelegate (object): def tableview_did_select(self, tableview, section, row): print(f'{items[row][0]}, {items[row][1]}') class MyTextFieldDelegate (object): items = items or [] def textfield_did_change(self, textfield): self.filter_data(textfield.text) def filter_data(self, filter_text=''): ft = filter_text.lower() if not len(ft): tbl.data_source.items = self.items else: for s in self.items: if ft in (s[0].lower()) or ft in (s[1].lower()): tbl.data_source.items = s ## Need this to be updated ## in the tableview view = ui.View(name='Filter Items', frame =(0,0,w,h), bg_color='slateblue') tf = ui.TextField(frame=(gap,gap,w-gap*2,32), flex='w', placeholder='Search', clear_button_mode='always') tf.delegate = MyTextFieldDelegate() view.add_subview(tf) tbl = ui.TableView(frame=(gap,42,w-gap*2,h-42), corner_radius=3, flex='wh') tbl.row_height=fontsize*2.5 tbl.name = 'Item Table' tbl.separator_color = 'grey' tbl.data_source = MyTableViewDataSource() tbl.delegate = MyTableViewDelegate() view.add_subview(tbl) view.present('sheet', title_bar_color= 'slateblue')

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.
