Python 'and', 'or', 'not' operator examples for beginners

📚 Quick Study Guide: Python Logical Operators

• 💡 The and operator returns True if and only if both operands are True. If the first operand is False, it immediately returns False (short-circuiting).
• 🔗 The or operator returns True if at least one of the operands is True. If the first operand is True, it immediately returns True (short-circuiting).
• 🚫 The not operator is a unary operator that inverts the boolean value of its operand. not True is False, and not False is True.
• ⚖️ Operator Precedence: not has the highest precedence, followed by and, then or. Parentheses () can be used to explicitly control the order of evaluation.
• 🔍 Truthiness: In Python, many non-boolean values are considered "truthy" or "falsy". For example, 0, None, empty strings "", empty lists [], and empty dictionaries {} are falsy. Non-empty versions are truthy.
