What is the output? How does it work mechanism? For Your Information:

Question

A =["a", "b", True, "c", False]
print("a" in arr) # return True
print(("a" in arr) in arr # return true
print((Bool(None) in arr) in arr
# return True

# since it works based on the presence of () which give a priority to the sequence of arithmetic operation to conduct.

Answer 1

Let's start Oliver Pasaribu . with there is either no A array or no arr array so let's correct this as

arr =["a", "b", True, "c", False]
print("a" in arr) # return True
print(("a" in arr) in arr ) # return True
print((bool(None) in arr) in arr )
# return True

Is 'a' in the array yes ( True )
Is 'a' in the array yes True and is True in the arr -> the answer is yes ( True )

bool(None) expression evaluates to False and yes False is in the array so True and is True in the array yes so the answer is True

In conclusion all 3 statements are True
