error when browsing files

[Scolpy]

Hello,
I have the following code:

import os
import appuifw
import e32
import dir_iter
import appuifw
from audio import*
import sys


def browse():
    appuifw.app.browse_files(__init__)
	
def exit():
    exit = appuifw.query(u"You want to exit?", "query")
    if exit:
        sys.exit(0)
    else:
        pass
		
		
global song
def play():
    global song
    s = appuifw.query(broswe)
    song = Sound.open(s)
    song.play()

def pause():
    global song
    song.stop()

def stop():
    global song
    Sound.close(song)

    def __init__(self):

        self.dir_stack = []

        if not self.current_dir.at_root:
            entries.insert(0, (u"..", u""))
        self.lb = appuifw.Listbox(entries, self.lbox_observe)
        self.lb.bind(EKeyLeftArrow, lambda: self.lbox_observe(0))
        old_title = appuifw.app.title
        self.refresh()
        self.script_lock.wait()
        appuifw.app.title = old_title
        appuifw.app.body = None

        else:
            index = self.lb.current()
        focused_item = 0

        if self.current_dir.at_root:
            self.dir_stack.append(index)
            self.current_dir.add(index)
        elif index == 0:                              
            focused_item = self.dir_stack.pop()
            self.current_dir.pop()
        elif os.path.isdir(self.current_dir.entry(index-1)):
            self.dir_stack.append(index)

            else:
                i = appuifw.popup_menu([u"Open", u"Delete"])
            if i == 0:
                if os.path.splitext(item)[1].lower() == u'.mp3':
                    execfile(item, globals())
                    self.refresh()
                   
                else:
                    try:
                        appuifw.Content_handler().open(item)
                    except:
                        import sys
                        type, value = sys.exc_info() [:2]
                        appuifw.note(unicode(str(type)+'\n'+str(value)), "info")
                return
            elif i == 1:
                os.remove(item)
                focused_item = index - 1

        entries = self.current_dir.list_repr()
        if not self.current_dir.at_root:
            entries.insert(0, (u"..", u""))
        self.lb.set_list(entries, focused_item)

if __name__ == '__main__':

    appuifw.app.menu = [(u"Browse", browse), (u"Play", play), (u"Pause", pause), (u"Stop", stop), (u"Exit", exit)]
    appuifw.app.exit_key_handler = exit
    appuifw.app.title = u"Vnixe Player"
    app_lock = e32.Ao_lock()
    app_lock.wait()
    Filebrowser().run()

It should serve me to build multimedia app.
When I try to activate the option to study - I get the following error:

Python:
System error(-50)

And where exactly does it say that appuifw.app has a browse_files method?

My wrong :S
Any idea what can be put in place?

Well, what do you want it to do?
If you want to search for files, this thread has examples for various kinds of searches. If you want to display files, take out the search part from those examples and leave the part that displays the files.

I did not mean for search data, but i mean to browse in files.

What I want to make this media player.
So who could run the files in the MP3, WMA, etc.
I want to make the option to browse in files on drives in the device

[bogdan.galiceanu]

Then like I said, try to modify the examples in that thread to display the files in the device's drives. There is a wiki article that gives examples for using basic functions like displaying all the files in a folder and all the files that have a certain extension. Maybe that will help you

Thank you for bringing me information.
But already created code. I just need to correct the error that appears when you browse in files.
And he will join with the correct codes of the music player wrote.

Hi,
can you please tell us what errors exactly you are getting?

You were getting that for reasons explained by Python. Python tells you what kind of error it is and even the line of code that causes it. All you have to do is read the error description carefully and I'm sure you'll be able to solve it.

The error is not specified on line (50).
And I did not know where the registered type of error.

[bogdan.galiceanu]

OK, so the first error is in "Browse", for that appuifw.app.browse_files() thing: AttributeError: browse_files. This means that appuifw.app has no attribute named browse_files.

Once you replace that with working code or delete it, move on to "Play": NameError: global name 'broswe' is not defined. This means that you haven't declared anything (variable, function, class, whatever) with the name browse.

So the idea is that in the PyS60 script shell, in that little green text, you get an error report that specifies the file where the error occured, the line, the function, it shows you the line and it gives you an explanation.

I know that there are no such attribute.
But you have no idea what a attributey I can put in place?

[bogdan.galiceanu]

You don't need to put an attribute there. You need to put the code to browse the files.

So it would be like:

def browse():
    #Code for browsing files goes here

Hi yonatan,

You can list the files from a directory by using os module:

import os

def list_musics():
    files = []
    PATH = "E:\\Musics\\"  # Your folder with music files
    musics = os.listdir(PATH) # Lists the files in the folder
    
    for f in musics:
        if os.path.splitext(f)[1] == '.mp3':
            files.append(unicode(f))
    return files

Hope it helps,

Rafael.
