    <p>In Python, I have a list of dicts as follows: </p> <pre><code>orig_list = [ {'first_name': u'Jake', 'last_name': u'Sarson', 'team': u'TeamOne', 'display_name': u'AVG', 'value': 7.0}, {'first_name': u'Mike', 'last_name': u'Walsh', 'team': u'TeamTwo', 'display_name': u'AVG', 'value': 12.0}, {'first_name': u'Jake', 'last_name': u'Sarson', 'team': u'TeamOne', 'display_name': u'AVG', 'value': 7.0}, {'first_name': u'Mike', 'last_name': u'Walsh', 'team': u'TeamTwo', 'display_name': u'AVG', 'value': 12.0}, {'first_name': u'Steve', 'last_name': u'Mottola', 'team': u'TeamTwo', 'display_name': u'AVG', 'value': 18.0}, {'first_name': u'Steve', 'last_name': u'Mottola', 'team': u'TeamTwo', 'display_name': u'AVG', 'value': 18.0}, {'first_name': u'Craig', 'last_name': u'Schubert', 'team': u'TeamOne', 'display_name': u'AVG', 'value': 23.5}, {'first_name': u'Steve', 'last_name': u'Mottola', 'team': u'TeamTwo', 'display_name': u'REC', 'value': 2.0}, {'first_name': u'Mike', 'last_name': u'Walsh', 'team': u'TeamTwo', 'display_name': u'REC', 'value': 1.0}, {'first_name': u'Jake', 'last_name': u'Sarson', 'team': u'TeamOne', 'display_name': u'REC', 'value': 1.0}, {'first_name': u'Craig', 'last_name': u'Schubert', 'team': u'TeamOne', 'display_name': u'REC', 'value': 2.0}, {'first_name': u'Craig', 'last_name': u'Schubert', 'team': u'TeamOne', 'display_name': u'TD', 'value': 1.0}, {'first_name': u'Steve', 'last_name': u'Mottola', 'team': u'TeamTwo', 'display_name': u'YDS', 'value': 36.0}, {'first_name': u'Jake', 'last_name': u'Sarson', 'team': u'TeamOne', 'display_name': u'YDS', 'value': 7.0}, {'first_name': u'Mike', 'last_name': u'Walsh', 'team': u'TeamTwo', 'display_name': u'YDS', 'value': 12.0}, {'first_name': u'Craig', 'last_name': u'Schubert', 'team': u'TeamOne', 'display_name': u'YDS', 'value': 47.0}] </code></pre> <p>I need to create a new list of dicts from the first list to find the unique names and for each name find all the display_name's and the values. In essence the result should be:</p> <pre><code>[{'first_name': u'Jake', 'last_name': u'Sarson', 'team': u'TeamOne', 'AVG': 7.0, 'REC': 1.0, 'YDS': 7.0}, {'first_name': u'Mike', 'last_name': u'Walsh', 'team': u'TeamTwo', 'AVG': 12.0, 'REC': 1.0, 'YDS': 12.0}, {'first_name': u'Steve', 'last_name': u'Mottola', 'team': u'TeamTwo', 'AVG': 18.0, 'REC': 2.0, 'YDS': 36.0}, {'first_name': u'Craig', 'last_name': u'Schubert', 'team': u'TeamOne', 'AVG': 23.5, 'REC': 2.0, 'TD': 1.0, 'YDS': 47.0}] </code></pre> <p>I tried with nested for loops but kept getting an error that the "dict is unhashable." What is the best solution for this data structure?</p>

    1. CODid you read about the dictionary `update` method yet? If not, please read that and revise your question.

    2. COThank you. I will read up on the update method. The python docs sometimes don't help me all the time and only if I see an example do I understand.

    3. CO"only if I see an example do I understand" Perhaps you should find a way to get past this. Python documentation is an excellent resource, and you'd able to solve problems more quickly if you could find a way to read them.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
