Why aren't these strings equal? (Python)
<pre><code>def getValue(d, key):
    for k, v in d.iteritems():
        print "{0} == {1}".format(k, key)
        if k == key:
            return v
        elif isinstance(v, dict):
            getValue(v, key)
    logging.error("Cannot find key in dictionary")
    return ""

#d = getting the dictionary

getValue(d, "error_frames")
</code></pre>

<p>From the print statement I inserted in the function, I clearly see "error_frames == error_frames" appear in the console, but the if statement is not getting executed. Why? The dictionary is constructed by parsing xml with the module xmltodict.</p>
