Python Coding Challenge - Question with Answer (ID 091026)

 

Explanation:

🟢 Step 1: Create a List

x = [True, 1, False, 0]

- A list named x is created with four elements.

- True and False are Boolean values.

- 1 and 0 are integers.

🟢 Step 2: Understand Boolean Equality

True == 1False == 0

- In Python, True == 1 evaluates to True.

- Similarly, False == 0 evaluates to True.

- This happens because Boolean values behave like integers in numeric comparisons.

🟢 Step 3: Understand the count() Method

x.count(True)

- The count() method counts how many elements in a list are equal to a specified value.

- Here, Python checks which elements in x compare equal to True.

🟢 Step 4: Check Each Element

Element Comparison Result

True True == True True

1 1 == True True

False False == True False

0 0 == True False

Therefore, two elements (True and 1) compare equal to True.

🟢 Step 5: Display the Result

print(x.count(True))

- x.count(True) returns 2.

- print() displays that value on the screen.

✅ Final Output

2
