How does Python handle situations where there are ambiguities with names when using multiple inheritance?

Python uses the Method Resolution Order (MRO) algorithm to handle ambiguities in multiple inheritance. MRO determines the order in which Python searches for methods and attributes in the class hierarchy.
The MRO algorithm is based on C3 linearization, which guarantees that each class appears exactly once in the search order and that the inheritance order is preserved.
Example:
class A:
def method(self):
print("A")
class B(A):
def method(self):
print("B")
class C(A):
def method(self):
print("C")
class D(B, C):
pass
obj = D()
obj.method() # Will print "B"
Here, when calling obj.method(), Python searches in class D, then in B, then in C, and finally in A, according to the MRO. This allows unambiguous determination of which method will be called, even with multiple inheritance.
