Conditional operators
1. Equality:
  ==: Equal to
  !=: Not equal to

2. Comparison:
  <: Less than
  >: Greater than
  <=: Less than or equal to
  >=: Greater than or equal to

3. Membership:
  in: Checks if a value exists in a sequence (e.g., list, tuple, string)
  not in: Checks if a value does not exist in a sequence

4. Identity:
  is: Checks if two variables refer to the same object
  is not: Checks if two variables do not refer to the same object
