def __init__(self, date_time=None):
self.date_time = data_time
def import_jira(self):
pass

def lazy_task():
def decorator(func):

In the file import_.py, RECIPIENTS is a static variable of the class Importer. This means, the variable RECIPIENTS needs to be accessed by <class-name>.<var-name>, which is this case is Importer.RECIPIENTS.
I would suggest you import Importer from import_.py and print Importer.RECIPIENTS instead of self.RECIPIENTS.
Add this line to the file decorators.py
from import_ import Importer
and change the print statement from print self.RECIPIENTS to
print Importer.RECIPIENTS
I wrote a simple example to make this work.
foo.py
class Foo:
VALUE = 'value'
def __init__():
pass
bar.py
from functools import wraps
from foo import Foo # importing class Foo from foo.py
def bar():
def decorator(func):
@wraps(func)
def inner():
print Foo.VALUE
return inner
return decorator
bar()(lambda: None)()
On running the file bar.py we get this output.
$ python bar.py
value
If you don't want to add an extra line of import statement at the top of every file that needs to use the RECIPIENTS value, you can directly import and print like this
print __import__('import_').Importer.RECIPIENTS
However, there is no other way of accessing a value from another file without importing it.

Thank you for your answer. But we used the same decorator for multiple tasks.py, So can you please tell us how to get them, RECIPIENTS.

Please check your facts. Python has nothing like "static variables", and class attributes CAN be accessed thru instances (which is how you can call methods on instances FWIW).
– bruno desthuilliers

Please check this question. Static variables can obviously be accessed by instances, but it's not necessary to create instances in order to access them. Please check your facts.

In your import_ function, the Importer instance is a local variable - not a function's argument -, so it can NOT be accessed by the decorator. Period.
