Python Conditionals and Loops Challenge Quiz

Test your understanding of Python's conditional statements and looping constructs with these challenging, concept-driven questions.

1. Nested If-Else Evaluation

   What is the output of the following code snippet?nx = 1ny = 2nif x u003E 0:n if y u003E 2:n print('A')n else:n print('B')nelse:n print('C')

   1. Break
   2. End
   3. None
   4. 4
   5. No output

    2. 2
    3. 5
    4. None
    5. 1

12. Truthiness in If Statements

    1. x = 0
    2. x = []
    3. x = ''
    4. x = None
    5. x = 'Python'
