Answer : A

==========

Step 1: The function receives the original price and the discount_percent.

Step 2: Convert the discount percentage into a decimal by dividing by 100.

Step 3: Subtract the discount from 1 to find the remaining price percentage.

Step 4: Multiply the original price by the remaining percentage.

Correct code:

def calculate_discount(price, discount_percent):

return price * (1 - discount_percent / 100)

Example:

print(calculate_discount(75, 20))

Output:

60.0

Answer : A

==========

Step 1: The expression number % 2 == 0 checks whether the number is even.

Step 2: The original code writes True and False, but it does not return them.

Step 3: A function must use the return statement to send a value back to the caller.

Correct code:

def is_even(number):

if number % 2 == 0:

return True

else:

return False

Simplified correct code:

def is_even(number):

return number % 2 == 0

Example:

print(is_even(4))

print(is_even(7))

Output:

True

False

Answer : B

The value 3.14 is afloatbecause it contains a decimal point.

Example:

type(3.14)

This returns:

<class 'float'>

Python's built-in numeric types include integers and floating-point numbers. A value with a decimal part, such as 3.14, is treated as a floating-point number.

Therefore, the correct answer isB. Float.

Answer : A

==========

Step 1: The function receives one string parameter named text.

Step 2: Python slicing can be used to reverse a string.

Step 3: The slice [::-1] means start at the end of the string and move backward by one character at a time.

Step 4: Return text[::-1].

Correct code:

def reverse_string(text):

return text[::-1]

Example:

print(reverse_string('hello'))

Output:

olleh

Answer : B

The .find() method returns the lowest index where the searched substring is found.

Example:

'learning python programming'.find('python')

Output:

9

Indexing starts at 0 in Python. In the string 'learning python programming', the word 'python' begins at index 9. Python's built-in types documentation describes str.find() as returning the lowest index where the substring is found.

Therefore, the correct answer isB. 9.
