You do it wrong. You shouldn't turn your code in quotes. Watch here how it should be

It should be like:

STATICFILES_DIRS = (
    os.path.join(os.path.dirname(__file__), "static")
)

Also it belongs to your MEDIA_ROOT and STATIC_ROOT settings.

All your db_table options end with a comma, which turns them into tuples. Remove those commas.

        db_table = 'renterinfo_addresses'

Note you will need to delete and recreate that migration.

You're passing a tuple instead of a string:

>>> sig = 'sig'
>>> 'oauth/token?blahblah&' + 'sig=%s', sig
('oauth/token?blahblah&sig=%s', 'sig')
>>> 'oauth/token?blahblah&' + 'sig=%s' % sig
'oauth/token?blahblah&sig=sig'

Replace the following line:

token_url = "oauth/token?" + urlencode(ksort(params)) + "&sig=%s",sig
                                                                 ^

with

token_url = "oauth/token?" + urlencode(ksort(params)) + "&sig=%s"%sig

MEDIA_ROOTshould be string, you are creating a tupple.

You are adding a ', 'comma, remove it to solve the issue. It is creating a tupple, we need a String.

in settings.py

MEDIA_ROOT = '%s/media' %PROJECT_PATH, change this to MEDIA_ROOT = '%s/media' %PROJECT_PATH it will solve the issue.

You return four variables s1,s2,s3,s4 and receive them using a single variable obj. This is what is called a tuple, obj is associated with 4 values, the values of s1,s2,s3,s4. So, use index as you use in a list to get the value you want, in order.

Copyobj=list_benefits()
print obj[0] + " is a benefit of functions!"
print obj[1] + " is a benefit of functions!"
print obj[2] + " is a benefit of functions!"
print obj[3] + " is a benefit of functions!"

have created a list in my code..

No you haven't you've create a tuple. Use a list instead:

lst = [x,y]

lst.append('red')
