Method Resolution Order (MRO) is the order in which classes are searched for a method or attribute in Python.
MRO is determined by the C3 linearization algorithm in Python.
It follows a depth-first left-to-right traversal of the class hierarchy.
MRO is important in multiple inheritance scenarios to resolve method conflicts.
Example: class A: pass class B(A): pass class C(A): pass class D(B, C)

Class method can be called on both the class and instances of the class.
Static method is mainly used for util...
