User defined method as variable or argument

[AeranicusCascadia]

I'll try to communicate this as clearly as possible. I am still fairly new. Thanks in advance!

Here is my issue, in a nutshell:

I have created a custom class with methods and instantiated it successfully.
I have created a list containing these instances.

When I call the method explicitly by referencing objects in my list by index, everything works fine.

When I store the method in a variable and try to apply it the same way I get an error ("name 'describe' is not defined").

Ultimately, I am trying to pass this user created method as an argument of a function, but the result is the same error as above.

Below is the pseudocode, which I think is the best way to communicate my problem.
All help is appreciated. I will clarify as best as I can. Thanks for your patience, I am trying to digest quite a few concepts here.


# Create custom class

class MyClass:

def constructor():
statement
statement

def my_method():
statment
statement

# Create some instances of custom class

item1 = MyClass()
item2 = MyClass()
item3 = MyClass()

# Create a list containing the instances

my_list = [item1, item2, item2]


[# This works perfectly:

result = my_list[index].my_method()


# This does not work:
# (Error = name 'my_method' is not defined)

m = my_method()
result = my_list[index].m

# This throws the same error:

my_function(my_list, my_method)

# However, the following works exactly as desired (obviously I adjust the parameters in the function definition according to which approach I am trying):

my_function(my_list).my_method()
