How to add image(s) from iPad camera roll to Pythonista image library

[Karina]

@cvp and how to add sounds that I need? For example, short guitar chords?

[cvp]

@Karina Sorry, do you want to import sound files into Pythonista? And, if yes, where are they?

[Karina]

@cvp I want to get more musical sounds like those that are already embedded, but don't know from where to take it and where to save. It's for a program in which I have musical instruments on the screen, and when tap, they play. I also want to do multi touch
Did you ever used your sounds in pythonista?

[cvp]

@Karina you can search mp3 in Google, import them in Pythonista and play them.
Or even play them as url. Try to search mp3 in the Pythonista forum

[cvp]

@Karina just for the fun

import tempfile
import sound
import requests
import ui

def play(url):
	with tempfile.NamedTemporaryFile(suffix='.caf') as fp:
		r = requests.get(url)
		r.raise_for_status()
		fp.write(r.content)
		sound.play_effect(fp.name)

v = ui.View()
v.background_color = 'white'

b_piano = ui.ButtonItem()
b_piano.title = '🎹'
def b_piano_action(sender):
	play('https://ccrma.stanford.edu/~jos/mp3/pno-cs.mp3')
b_piano.action = b_piano_action

b_violon = ui.ButtonItem()
b_violon.title = '🎻'
def b_violon_action(sender):
	play('https://ccrma.stanford.edu/~jos/mp3/violin.mp3')
b_violon.action = b_violon_action

v.right_button_items = (b_piano,b_violon)
v.present('fullscreen')

@Karina Sorry, I didn't understand your request. What I show is how to play an entire mp3, not a sound like standard ones. Sincerely sorry, forget my post.

[cvp]

@Karina you can download a mp3 file and store it in your folders, like an image.
And then, play it like a standard Pythonista file.

[cvp]

@Karina run this little script once to download a mp3 as a Pythonista file

import requests
url = 'https://ccrma.stanford.edu/~jos/mp3/pno-cs.mp3'
with open('mypiano.mp3',mode='wb') as fil:
	r = requests.get(url)
	fil.write(r.content) 

then run your script with this little modif

piano_sounds = ['mypiano.mp3']#piano:A3', 'piano:C3', 'piano:C4#', 'piano:D4', 'piano:E4', 'piano:F4', 'piano:G3#'] 

[Karina]

@cvp thanks, I'll try

[PinhoBD]

@cvp Hi, I tried your approach: +, import, files, Browse, and pick an image file, say, abc.jpg. It imported the file into the current directory, say, /Examples/abc.jpg and the image of abc. But when I checked the + at the lower right corner of the script editor, then clicked open files. There is neither image of abc nor abc.jpg file. I would like to import an image file into + / images/files, so that I can easily enter the image using ui.Imag e.named().I did try many times and some how I did succeed once,but I couldn’t repeat. Please help. Thanks a lot.

[cvp]

@PinhoBD strange. In + / images / files, I see my thousands images, after some time, I agree

[PinhoBD]

Thank you. I finally saw the file I imported a few hours before. Now I believe I did the right things. If I can repeat it the second time, I should be able to repeat it again and again. I appreciate your help!!
