I have a class
Person and a static method in that class called
class Person: def call_person(): print "hello person"
In the python console I import the class Person and call
Person.call_person(). But it is giving me error that says
'module' object has no attribute 'call_person'. Can anyone please let me know why I am getting this error?
You need to do something like:
class Person: @staticmethod def call_person(): print("hello person") # Calling static methods works on classes as well as instances of that class Person.call_person() # calling on class p = Person() p.call_person() # calling on instance of class
Depending on what you want to do, a classmethod might be more appropriate:
class Person: @classmethod def call_person(cls): print("hello person", cls) p = Person().call_person() # using classmethod on instance Person.call_person() # using classmethod on class
The difference here is that in the second example, the class itself is passed as the first argument to the method (as opposed to a regular method where the instance is the first argument, or a staticmethod which doesn’t receive any additional arguments).
Now to answer your actual question. I’m betting that you aren’t finding your method because you have put the class
Person into a module
import Person # Person class is available as Person.Person Person.Person.call_person() # this should work Person.Person().call_person() # this should work as well
Alternatively, you might want to import the class Person from the module Person:
from Person import Person Person.call_person()
This all gets a little confusing as to what is a module and what is a class. Typically, I try to avoid giving classes the same name as the module that they live in. However, this is apparently not looked down on too much as the
datetime module in the standard library contains a
Finally, it is worth pointing out that you don’t need a class for this simple example:
# Person.py def call_person(): print("Hello person")
Now in another file, import it:
import Person Person.call_person() # 'Hello person'
