Question

Let me start by saying that I’ve never coded in Python.

I need to make an API call to upload a bunch of files from my local machine to a server. On the server, I want to take the file name of the files and assign the string sans the extension to a variable called ‘identifier.’

import requests
import os
url = 'http://someplace'
folder = 'path/to/folder/'
for card in os.listdir(folder):
    data = {'identifier': PyFile_Name(PyObject *p), 'type': 'Inventory Card'}
    files = {'card': open(os.path.join(folder, card), 'rb')}
    requests.post(url, data=data, files=files, auth=('username', 'pass'))

Am I doing this right?

Answer 1

You should be using

import requests
import os
url = 'http://someplace'
folder = 'path/to/folder/'
for card in os.listdir(folder):
    data = {'identifier': '.'.join(card.split('.')[:-1]), 'type': 'Inventory Card'}
    files = {'card': open(os.path.join(folder, card), 'rb')}
    requests.post(url, data=data, files=files, auth=('username', 'pass'))

'.'.join(card.split('.')[:-1]) takes the filename (in card), splits it into components that were separated by a period in the file name, rejects the last element of the list [:-1] and rejoins the filename minus the extension.

Using this syntax will handle filenames with multiple periods such as foo.20120613.txt

EDIT:

An example that lists files in my ~/tmp directory…

[mpenning@Bucksnort tmp]$ ls
howto  regex_trial.xml  soln.py
[mpenning@Bucksnort tmp]$
[mpenning@Bucksnort tmp]$ python

>>> import os
>>> for card in os.listdir('./'):
...     print "card:", card
...     print " base_name:", '.'.join(card.split('.')[:-1])
...
card: howto
 base_name:
card: regex_trial.xml
 base_name: regex_trial
card: soln.py
 base_name: soln
>>>

Note that howto is a directory… you need to put logic in your script to skip a directory if there is one in this path.
