Version control system. http://en.wikipedia.org/wiki/List_of...ntrol_software
Make your module a versioned repository.
Make your changes in different place, then commit them.
I use SVN and mercurial.

You simply run the module's unit tests that tell you if the new module's
behaviour differs from the expectations. If you don't have unit tests, I'd
say it's about time writing them.

Don't ;-)
If the changes are that extensive it might be considerable to write a new
module and switch the depending code to use that new module when you're
done and they're ready.
As mentioned in another posting revision control is a good thing as well.
Not just for that task.

From my point of view revision control is not a question but a fact.
Seriously, if you are not using any RCS already, it is about time you start
doing so. I even use it for my private toy projects.

If I'm understanding you correctly: you want to load the old module
when running code normally, but want to use a new module when
developing, but is has to have the same name?
Here's what you could do:
1. Rename "whatever.p y" to "oldwhatever.py ".
2. Copy "oldwhatever.py " to "newwhatever.py ", and make your extensive
changes there.
3. Create a new "whatever.p y" with code that imports all the symbols
from the old or new module depending on which module you want to use.
For instance, you could use an environment variable to choose which
one:
if os.environ.get( "USENEWMODU LE") == "yes":
from newwhatever import *
else:
from oldwhatever import *
Or, you could set a flag in some sort of configuration module and
check that:
import config
if config.use_new_ module:
from newwhatever import *
else
from oldwhatever import *

That doesn't seem like a good solution for the OP's particular
problem. To do it in a "different place", as you say, he'd have to
check out a new working copy, which might be a bit of overkill
depending on the size of the project. It could also be problematic to
have separate working copies; there could be programs outside the
project that are configured to use a certain location, for instance.
One thing you could do with some version control systems is to switch
the particular version for the module in question between different
branches depending on whether you're using the tools or changing the
model. (Subversion can do this, but I'm not sure if it's for
individual files or only directories.)

Do you mean you want to hot-patch a running program? The short answer
is: don't. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Sometimes I have a function which creates an object and returns it.
Some are sets, other vectors but that's not very important. In these
