Question

What will be the output of the following Python code? class A: def test1(self): print(" test of A called ") class B(A): def test(self): print(" test of B called ") class C(A): def test(self): print(" test of C called ") class D(B,C): def test2(self): print(" test of D called ") obj=D() obj.test()

Answer 1

"test of B called"

Step-by-step explanation:

• The object is created for the D class, but there are two test methods in class B and C.
• The D class does not hold any test method. So when the object called the test method. Then the B method is called.
• It is because the B class is declared first in the inheritance of D class like in the statement "class D(B, C)".
• If the statement will be "class D(C, B)", then the C method will be called.
• if the D class holds the method test, then only the D method will be called.
• Hence the output is "test of B called".
