I've got a module that I use regularly. I want to make some extensive

the module to keep working while I'm making my changes. What's the
best way to accomplish this?
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.py" to "oldwhatever.py".
2. Copy "oldwhatever.py" to "newwhatever.py", and make your extensive
changes there.
3. Create a new "whatever.py" 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("USENEWMODULE") == "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 *
