POMulti-line dictionaries: Replace the key as per a word in value
text
Body
copied!<p>I have a dictionary in which I have to replace all the keys depending on a word in the value set. So my dictionary is: <br></p> <pre><code> { 23: {'score': -8.639, 'char': False, 'word': 'positive'} } { 56: {'score': -5.6, 'char': False, 'word': 'neutral'} } { 89: {'score': -8.9, 'char': False, 'word': 'positive'} } { 34: {'score': -2.3, 'char': Tru, 'word': 'negative'} } </code></pre> <p>If the values part of dictionary i.e. the key word is positive then it should replace the key 23 with +1, for neutral's, the key 56 with 0 and for negative, the key 34 with -1. The output will look like:<br></p> <pre><code> { +1: {'score': -8.639, 'char': False, 'word': 'positive'} } { 0: {'score': -5.6, 'char': False, 'word': 'neutral'} } { +1: {'score': -8.9, 'char': False, 'word': 'positive'} } { -1: {'score': -2.3, 'char': Tru, 'word': 'negative'} } </code></pre> <p>Here is my code:</p> <pre><code>for n, line in enumerate(sys.stdin,1): d = ast.literal_eval(line) items = d.values()[0].items() if re.match("positive",d.get('sentimentoftweet')): n = str.replace(str(n),"+1") else: n = str.replace(str(n),"0") </code></pre> <p>Its not working and giving me this error:</p> <pre><code>Traceback (most recent call last): File "./linear.py", line 33, in <module> for thing in d: File "./linear.py", line 22, in gen_with_appropriate_name if re.match("positive",d.get('sentimentoftweet')): File "/usr/lib/python2.7/re.py", line 137, in match return _compile(pattern, flags).match(string) TypeError: expected string or buffer </code></pre>
