This attachment is a screenshot of a more readable result.

Description of problem:

The Python code section at
http://docs.fedoraproject.org/en-US/Fedora_Draft_Documentation/0.1/html/RPM_Guide/ch16s03s05.html
has an error in the following code: 

    # Dependencies
    print "Provides:"
    print h.dsFromHeader('providename')

    print "Requires:"
    print h.dsFromHeader('requirename')

    if h.dsFromHeader('obsoletename'):
        print "Obsoletes:"
        print h.dsFromHeader('obsoletename')

    if h.dsFromHeader('conflictname'):
        print "Conflicts:"
        print h.dsFromHeader('conflictname')

print h.dsFromHeader('conflictname') outputs <rpm.ds object at 0xb77584b8>. 

h.dsFromHeader('conflictname'), without the "print" word, outputs it right. 


Version-Release number of selected component (if applicable):
0.1

How reproducible:


Steps to Reproduce:
1. Copy the python code from the page to a file called rpminfo.py on a computer
that has the older version of Python, Python 2.
2. Run the Python code, by running the "cd" command until you get to the folder
that contains rpminfo.py.  
3. Run rpminfo.py by entering the command python rpminfo.py. 

Actual results:

Provides:
<rpm.ds object at 0xb77584b8>
Requires:
<rpm.ds object at 0xb77584b8>

Expected results:

Provides:
P config(httpd) = 2.2.15-39.el6.centos
Requires:
R libapr-1.so.0

Additional info:

The members of the object returned by dsFromHeader have integer indexes, since
the following code produces a more readable result: 

     # Dependencies
    print "Provides:"
    print h.dsFromHeader('providename')[0]

    print "Requires:"
    print h.dsFromHeader('requirename')[0]
