a neater way of importin multiple modules

[s...@weacceptyou.com]

Hi there,

i have a 'run' script which is importing all of the relevant modules to make my program run. The script is quite long with roughly 12 modules that are imported and run one after the other. Along with each import statement there is also the 'reload()' thing to make it reload the code. eg:

----------------------------------------------------------

import samDev.rigging.TOPOCOAT.config as config
reload(config)
import samDev.rigging.TOPOCOAT.utility_functions.subdivide_curves as subdivide_curves
reload(subdivide_curves)
import samDev.rigging.TOPOCOAT.utility_functions.general as general
reload(general)
import samDev.rigging.TOPOCOAT.utility_functions.circle_config as circle_config
reload(circle_config)
import samDev.rigging.TOPOCOAT.build_body_parts as body
reload(body)

etc (up to 12 modules or so)
------------------------------------------------------------

But i want to keep my 'run' script looking clean, is there a neater/tighter way to write all this?

thanks alot,
Sam

If you think it would be cleaner and more readable you could look at using a list of strings, and the __import__ function

k thanks Justin.

Also say theres a bunch of different modules in one folder. Do i need to import each module individually.

Or is there a way to just import the folder and access the modules individually in the script when theyre needed?

thanks,
Sam

You should look into expressing that via your packages __init__.py

https://docs.python.org/2.7/tutorial/modules.html#packages

The package can import all the modules it wants. Then your higher level package can do a "from subpackage import *"

there's probably a variety of ways to do it.

import os

def moduleList(folder=None):

modules = []

folder = os.path.dirname(__file__) if folder is None else folder
for (dirpath, dirnames, filenames) in os.walk(folder):

modules += [f[:-3] for f in filenames if f.endswith(".py") and f != "__init__.py"]
modules += [d for d in dirnames if os.path.exists(os.path.join(folder, d, "__init__.py"))]
break

return sorted(modules)


for moduleName in moduleList():
__import__(moduleName, globals(), locals(), ["*"], -1)

I might have done it this way.

from samDev.rigging.TOPOCOLAT import (
    config,
    subdivide_curves,
    general,
    circle_config,
    build_body_parts as body
)

And reloaded maybe this way.

for module in (config,
               subdivide_curves,
               general,
               circle_config,
               body):
    reload(module)
