# Define two variables
a = 20
b = 10

# Example 1: Using a comparison operator
result = (a > b)
print(f"Is {a} greater than {b} ? {result}")

# Explanation:
# The expression `a > b` compares the value of `a` (10) with the value of `b` (5).
# Since 10 is indeed greater than 5, the expression evaluates to `True`.

# Example 2: Using a logical operator (AND)
c = True
d = False
result_1 = (c and d)
print(f"Is {c} AND {d} true? {result_1}")

# Explanation:
# The expression `c and d` uses the logical AND operator.
# The `and` operator returns `True` only if *both* operands are `True`.
# Since `d` is `False`, the entire expression evaluates to `False`.

# Example 3: Using the bool() function to evaluate "truthiness"
empty_string = ""
non_empty_string = "Hello"
result_2 = bool(empty_string)
result_3 = bool(non_empty_string)
print(f"Is an empty string considered True? {result_2}")
print(f"Is a non-empty string considered True? {result_3}")

# Explanation:
# The `bool()` function returns the boolean value of an object based on its "truthiness".
# An empty string is considered "falsy" in Python, so `bool(empty_string)` returns `False`.
# A non-empty string is considered "truthy", so `bool(non_empty_string)` returns `True`.
