Asetstores only unique elements. If duplicate values are added, Python keeps only one copy.
Example:
numbers = {1, 2, 2, 3}
print(numbers)
Output:
{1, 2, 3}
Python's data structures documentation describes sets as collections with no duplicate elements.
Therefore, the correct answer isD. Set.

See the Step by Step Solution below in Explanation.
Explanation:
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

See the Step by Step Solution below in Explanation.
Explanation:
Step 1: First, check the password length using len(password).
Step 2: If the password has fewer than 8 characters, return " Weak " immediately.
Step 3: Create two Boolean variables: has_letter and has_number.
Step 4: Loop through each character in the password.
Step 5: Use .isalpha() to check for letters and .isdigit() to check for numbers.
Step 6: If the password contains both at least one letter and at least one number, return " Strong " .
Step 7: Otherwise, return " Weak " .
Correct code:
def password_strength(password):
if len(password) < 8:
return " Weak "
has_letter = False
has_number = False
for char in password:
if char.isalpha():
has_letter = True
elif char.isdigit():
has_number = True
if has_letter and has_number:
return " Strong "
else:
return " Weak "
Example:
print(password_strength( " abc123def " ))
print(password_strength( " abcdefgh " ))
print(password_strength( " 12345678 " ))
Output:
Strong
Weak
Weak

The correct Python for loop syntax uses the keyword in.
Correct code:
for name in [ ' Alice ' , ' Bob ' , ' Carol ' ]:
print(name)
This loop processes each name in the list one at a time. Python's documentation explains that a for statement iterates over the items of a sequence or iterable.
Therefore, the correct answer isA. for name in [ ' Alice ' , ' Bob ' , ' Carol ' ]:.
