How decoupled are the Python frameworks?

Hi I'm getting back into Python after a long break. I've been developing large enterprise apps solely with Adobe Flex (ActionScript) for the past couple years. During that time I've used a number of 'MVC' frameworks to glue the bits together - among them Cairngorm, a modified implementation of C

test if an input string starts with a python expression

Hi, i'd like to test if an input string starts with a python expression and also where that expression ends. An example: a_func(3*7, '''abc''') +5 pls some more The first part until (inclusive) the 5 should be found as an expression and the length of that string should also be detected. Backg
