Hi
In addition to what has already been said.
Make use of command line search tools. Hoe to search through all the python
files using BASH is a good example.
eg: In one of my projects i have to find all the places where a particular
class is called or instantiated: 'LocationAirfieldLookup'
find . -name '*.py' -exec grep -E -H -n 'import LocationAirfieldLookup'
'{}' \; -print
will return every python file where that is instantiated:
/users/views.py:94: from Aeroclub.common.LocationsUtils import
LocationAirfieldLookup
Very useful.
Firstly, get an idea of what each 'app' eg: polls app in the tutorial is
supposed to do. Where its functionality starts/ends, what common resources
it uses.
Then i look at the various urls.py files with a conventional analoge
notepad nearby to map out some of the important stuff.
I also look at models.py for important parts of the software.(afterall this
is how it uses the DB). Here you may want to use a tool like grep to just
get the class names.
models often have a lot of custom functionality in them. Eg: cusomised
'save' methods etc.
This all really boils down to good documentation practices. If there's good
docs then its easier, otherwise expect to spend a day or two learning to
understand the program.
cheers
