PCEP-30-02 Exam - Question 1

I tested the code: list = [False, True, "2", 3, 4, 5] b = 0 in list print(b) The answer is "C":

A is correct. 0 is not in the list, hence its True

Correct Answer is C True boolean value is 0, so it can be considered as 0 is in the list. Please try in the python lab to check it if you are confused.

c is the correct answer because in Python, False is equivalent to 0, and True is equivalent to 1. When checking if 0 is in a list using the in operator, Python will return True if False is present in the list because 0 == False.

Let's evaluate each option: Option A will result in b = 0 not in list which checks if 0 is not in the list. Since 0 is not in the list, this will result in True. Option B will result in b = list[0] which assigns False to b. Option C will result in b = 0 in list which checks if 0 is in the list. Since 0 is not in the list, this will result in False. Option D will directly assign False to b. Since we want the output to be True, option A is the correct one

A is correct In Python, the comparison 0 in list evaluates to True because False is treated as equivalent to 0. Here’s an explanation: False is equivalent to 0 in Python (and True is equivalent to 1). When checking 0 in list, Python finds False in the list, which is equivalent to 0. Thus, the condition 0 in list returns True.

It is C. 0 denotes false in python. So b in list is false, which returns true

c is the correct answer

I second yan45

option A

The answer is "C": if 0 in list #return True, so b=True and print b return True

The correct answer is C

False is seen by Python as 0, therefore the correct answer is C.

0=False in python and false is there hence it is C

0 equal False so choose C

cuz 0 = False

B is the right answer after strategical analysis.

The element False in list could be interpreted as 0 (False = 0), so the evaluation of 0 in list will give True as result

False == 0 # True True == 1 # True

0 considered as False. And False option is present in list. Hence, Option C is the correct one.
