Proper use of objects in Python

Question

# --- PYCode ----------------------

1 : class myClass:
2 : def works_with (self):
3 : print("Hello!")
4 :
5 : def works_without():
6 : print ("Hello!")
7 :
8 : # --- creating object ---
9 : mC = myClass()
10 : mC.works_with()

# --- PYCode ----------------------
Case 1:
I know that the proper way declaring objects in python is "mC = myClass()" and the above works.
And if I leave everything as it is and replace the 10-th line to "mC.works_without()" it won't work.

However:
Case 2:
If I change 9-th line to "mC = myClass" and 10-th line to "mC.works_without()" it will work.
But if I change 5-th line to "def works_without(self):" and 9-th line to "mC = myClass" and 10-th line to "mC.works_without()" it won't work.

So, how the objects in Python should be used and what are the differences between 2 cases above?

Answer 1

class myClass:

def works_without():
print ("Hello! blank")

def works_with (self):
print("Hello! self")

# x = myClass() creates an instance
# x = myClass creates a reference to the class name

# Instance syntax options for any 'self' defined method
inst = myClass()
inst.works_with() # option 1
myClass.works_with(inst) # option 2

# Using className options for properties with no self reference
myClass.works_without() # option 3
a_reference = myClass

# compare
a_reference.works_with(inst) # option2 equivilent
a_reference.works_without() # option3 equivilent
