[Tutor] read cell phone's directory?

[= Clayton - Tang =]

Hi all,

I am on WIndows and have an Android cell phone running Android 4.4.4.

When I connect the phone to my PC using a micro-USB cable, the phone appears
next to the local hard drive under "This PC" window, then I can browse the
phone's directory like a regular disk. My goal is to find all the photos on the
phone then do something with the files. So I copied the path from the File
Explore navigation bar, which is 'This PC\Nexus 5\Internal storage\DCIM\Camera',
but the follow code doesn't work.

I get an error "W indowsError: [Error 3] The system cannot find the path
specified: 'This PC\\Nexus 5\\Internal storage\\DCIM\\Camera/*.*". Does anyone
know who to make it work?


import os;

## Example pulls filenames from a dir, prints their relative and absolute paths
def printdir(dir):
  filenames = os.listdir(dir)
  for filename in filenames:
print filename ## foo.txt
print os.path.join(dir, filename) ## dir/foo.txt (relative to current dir)
print os.path.abspath(os.path.join(dir, filename)) ## /home/nick/dir/foo.txt
print

if __name__ == '__main__':
  printdir('This PC\Nexus 5\Internal storage\DCIM\Camera')

This was recently discussed on the main list (python-list aka
comp.lang.python). Long story short, modern Android phones are using the
MTP protocol and do not behave like usual USB drives. You must use a module
that implements MTP if you want to access your phone.

No need for a semicolon here.

Hmmm... there are a few things you may need to resolve.

1.  Backslashes have a meaning in Python string literals.  They mark
the beginning of an escape character sequence, to let programmers
represent strings that contain characters that are hard to otherwise
type.

See:

http://learnpythonthehardway.org/book/ex10.html

2.  "This PC" may be simply a convenient name that Windows 8.1 is
using in its user interface.  It may be mapped to a different location
on your hard drive than a directory called "This PC".  Unfortunately,
I have no experience with Windows 8.1, so hopefully someone else might
be able to investigate.

Don't use regular expressions for HTML. Use lxml instead.

Also, why would you need that exact thing? It's useless. Also, this code is
very ugly, with too many s and — worse — s which should not be
used at all.

Chris, thanks for the reply. I don't have newsgroup access, can you point me to

You don't need it. Use the official mailing list that is mirrored to Usenet.

Main page with subscribe link:

The thread does not have any ready answer just yet, it's currently busy
arguing about the protocol. You can Google the term “python MTP”, you may
find some answers there.

Why lxml and not bs? I read that bs deals better with malformed html. You said 
the above html is messy, which is not necessarily the same as malformed, but.. 
Anyway, this reference also seems to favor lxml:

Hi Sarma,


Following up on this one.  I'm pretty sure that:

print re.search("https://docs.python.org/2/howto/regex.html#greedy-versus-non-greedy

Re: [Tutor] re module

[Danny Yoo]

Hi Sunil,

Don't use regular expressions for this task.  Use something that knows
about HTML structure.  As others have noted, the Beautiful Soup or
lxml libraries are probably a much better choice here.

There are good reasons to avoid regexp for the task you're trying to
do.  For example, your regular expression:

 ">> import re
>>> m = re.match("'(.*)'", "'quoted' text, but note how it's greedy!")
>>> m.group(1)
"quoted' text, but note how it"
##

and note how the match doesn't limited itself to "quoted", but goes as
far as it can.

This shows at least one of the problems that you're going to run into.
Fixing this so it doesn't grab so much is doable, of course.  But
there are other issues, all of which are little headaches upon
headaches.  (e.g. Attribute vlaues may be single or double quoted, may
use HTML entity references, etc.)

So don't try to parse HTML by hand.  Let a library do it for you.  For
example with Beautiful Soup:

http://www.crummy.com/software/BeautifulSoup/bs4/doc/

the code should be as straightforward as:

###
from bs4 import BeautifulSoup
soup = BeautifulSoup(stmt)
for span in soup.find_all('span'):
print span.get('style')
###

where you deal with the _structure_ of your document, rather than at
the low-level individual characters of that document.
