python __import__ from same folder fails
I have a directory structure like so:
|- project
|- commands.py
|- Modules
| |- __init__.py
| |- base.py
| \- build.py
\- etc....
I have the following code in __init__.py
commands = []
hooks = []
def load_modules():
""" dynamically loads commands from the /modules subdirectory """
path = "\\".join(os.path.abspath(__file__).split("\\")[:-1])
modules = [f for f in os.listdir(path) if f.endswith(".py") and f != "__init__.py"]
print modules
for file in modules:
try:
module 开发者_StackOverflow= __import__(file.split(".")[0])
print module
for obj_name in dir(module):
try:
potential_class = getattr(module, obj_name)
if isinstance(potential_class, Command):
#init command instance and place in list
commands.append(potential_class(serverprops))
if isinstance(potential_class, Hook):
hooks.append(potential_class(serverprops))
except:
pass
except ImportError as e:
print "!! Could not load %s: %s" % (file, e)
print commands
print hooks
I'm trying to get __init__.py
to load the appropriate commands and hooks into the lists given, however i always hit an ImportError at module = __import__(file.split(".")[0])
even though __init__.py
and base.py etc are all in the same folder. i have verified that nothing in any of the module files requires anything in __init__.py
, so i'm really at a loss of what to do.
All you're missing is having Modules on the system path. Add
import sys
sys.path.append(path)
after your path = ...
line and you should be set. Here's my test script:
import os, os.path, sys
print '\n'.join(sys.path) + '\n' * 3
commands = []
hooks = []
def load_modules():
""" dynamically loads commands from the /modules subdirectory """
path = os.path.dirname(os.path.abspath(__file__))
print "In path:", path in sys.path
sys.path.append(path)
modules = [f for f in os.listdir(path) if f.endswith(".py") and f != "__init__.py"]
print modules
for file in modules:
try:
modname = file.split(".")[0]
module = __import__(modname)
for obj_name in dir(module):
print '%s.%s' % (modname, obj_name )
except ImportError as e:
print "!! Could not load %s: %s" % (file, e)
print commands
load_modules()
