Python Logical Operators

Use `and`, `or`, and `not` to build expressive conditions without confusing side effects.

Operator behavior

Operator	Behavior
and	Returns first falsy operand, otherwise the last operand
or	Returns first truthy operand
not	Inverts truthiness

Example:

user = cached_user or fetch_user()
if user and user.active:
    welcome(user)

Short-circuit

• and stops evaluating once a falsy value is found.
• or stops after the first truthy value.

This makes logical operators great for lazy evaluation but can hide bugs if you rely on side effects.

Tips

• Use parentheses for clarity in complex expressions.
• Don't chain too many conditions; extract them into helper variables.
