I have something roughly like the following. Basically I need to access the class of an instance method from a decorator used upon the instance method in its definition.
def decorator(view):
# do something that requires view"s class
print view.im_class
return view
class ModelA(object):
@decorator
def a_method(self):
# do some stuff
pass
The code as-is gives:
AttributeError: "function" object has no attribute "im_class"
I found similar question/answers - Python decorator makes function forget that it belongs to a class and Get class in Python decorator - but these rely upon a workaround that grabs the instance at run-time by snatching the first parameter. In my case, I will be calling the method based upon the information gleaned from its class, so I can"t wait for a call to come in.

How can I make a time delay in Python?
5 answers
I would like to know how to put a time delay in a Python script.
Answer #1
import time
time.sleep(5) # Delays for 5 seconds. You can also use a float value.
Here is another example where something is run approximately once a minute:
import time
while True:
print("This prints once a minute.")
time.sleep(60) # Delay for 1 minute (60 seconds).
Answer #2
You can use the sleep()
function in the time
module. It can take a float argument for sub-second resolution.
from time import sleep
sleep(0.1) # Time in seconds

Simply put and clear. Thank you for sharing. Can a decorator of an instance method access the class? and other issues with io Python module was always my weak point 😁. I am just not quite sure it is the best method
