Exam PCAP topic 1 question 102 discussion

There is a typo in answer C. "var" should be capitalized "Var": class Class: Var = data = 1 def __init__(self,value): self.prop = value Object = Class(2) print(len(Class.__dict__) == 1) # False print("data" in Class.__dict__) # True print("Var" in Class.__dict__) # True print("data" in Object.__dict__) # False print(Class.__dict__) print("*************") print(Object.__dict__)

print(isinstance(obj_b,A)) # ans A, The isinstance() function returns True # if the specified object is of the specified type # return false print(A.VarA ==1) # ans B, A.VarA = 1, so A.VarA ==1. Then,it return true print(obj_a is obj_aa) # ans C, return false print(B.VarA == 1) # ans D, B.VarA = 2, so B.VarA not == 1. Then, it return false The correct answer should be B,C

The correct answer should be B and C

Correct Answer should be BC

Correct Answer should be BC

only correct answer is: B. 'data' in Class.__dict__ If it was 'Var' instead, also: C. 'var' in Class.__dict__

Tested. BC

>>> Object.__dict__ {'prop': 2} >>> Class.__dict__ mappingproxy({'__module__': '__main__', 'Var': 1, 'data': 1, '__init__': <function Class.__init__ at 0x100efd040>, '__dict__': <attribute '__dict__' of 'Class' objects>, '__weakref__': <attribute '__weakref__' of 'Class' objects>, '__doc__': None}) >>>

B (also C if 'Var')

for me BC is correct

BC is correct
