    <p>Hi I am trying to be able to start a thread from a dictionary entry using this code below. The rest of the code in the script is known good and fully functional. I cam gonna have to be able to choose from a bunch of different subroutines so I want to remove as much boilerplate as possible from the code. Thanks guys and gals!!!!</p> <pre><code>class worker_manager: i = test_imports() template('one': i.import_1, 'two': i.import_2); def __init__(self): self.children = {} def generate(self, control_Queue, threadName, runNum): p = multiprocessing.Process(target=self.template[threadName], args=(control_Queue, runNum)) self.children[threadName] = p p.start() def terminate(self, threadName): self.children[threadName].join </code></pre> <p>When I run this code I get this error:</p> <pre><code> File "dynamicTest1.py", line 53 template('one': i.import_1, 'two': i.import_2); ^ SyntaxError: invalid syntax </code></pre> <p>Anyone have any advice? </p> <p>EDIT: Here is how a normal thread works:</p> <pre><code>def generate(self, control_Queue, threadName, runNum): i = test_imports() if threadName == 'one': print ("Starting import_1 number %d") % runNum p = multiprocessing.Process(target=i.import_1, args=(control_Queue, runNum)) self.children[threadName] = p p.start() </code></pre> <p>I wanna replace target in <code>p = multiprocessing.Process(target=i.import_1, args=(control_Queue, runNum))</code> with a dictionary to remove the need for what was a MASSIVE amount of if/elif/else statements.</p>

    1. COWell, it's not Python syntax, that's why ;-) I don't know what you **intend** that line to do, but it's not legal syntax for anything. If you're trying to pass a dict as an argument to the template function, then you need `template({'one': i.import_1, 'two': i.import_2})`

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.
