Operators like == (equal to), != (not equal to), < (less than), and > (greater than) compare values and always produce a boolean result: True or False. Logical operators combine these boolean outcomes, allowing for more complex conditional expressions.Often, you need to check more than one condition at a time. For instance, you might want to know if a user is both logged in and has administrator privileges, or if it's either Saturday or Sunday. This is where logical operators come into play. They allow you to combine boolean values (True or False) to create more complex conditions. Python provides three logical operators: and, or, and not.The and OperatorThe and operator evaluates two boolean expressions. It returns True only if both expressions are True. If either expression (or both) is False, the result is False.Think of it like needing two forms of identification to enter a secure area. You need ID card A and ID card B. Having only one isn't enough.Let's look at an example:age = 25 has_ticket = True # Is the person old enough AND has a ticket? can_enter = (age >= 18) and (has_ticket == True) print(f"Age is 25, has ticket: {can_enter}") # Output: True age = 16 # Now the first condition (age >= 18) is False can_enter = (age >= 18) and (has_ticket == True) print(f"Age is 16, has ticket: {can_enter}") # Output: False age = 30 has_ticket = False # Now the second condition (has_ticket == True) is False can_enter = (age >= 18) and (has_ticket == True) print(f"Age is 30, no ticket: {can_enter}") # Output: FalseThe parentheses () around the comparisons (age >= 18) are not strictly required here because and has lower precedence than comparison operators, but they often make the code easier to read by clearly grouping the conditions.Here's a summary of how and works:Condition 1Condition 2Condition 1 and Condition 2TrueTrueTrueTrueFalseFalseFalseTrueFalseFalseFalseFalseThe or OperatorThe or operator also evaluates two boolean expressions. It returns True if at least one of the expressions is True. It only returns False if both expressions are False.Imagine getting a discount if you are either a student or a senior citizen. Meeting just one of the conditions is sufficient.Consider this example:is_weekend = False is_holiday = True # Is it the weekend OR a holiday? day_off = is_weekend or is_holiday print(f"Weekend: False, Holiday: True -> Day off: {day_off}") # Output: True is_weekend = True is_holiday = False # The first condition is True day_off = is_weekend or is_holiday print(f"Weekend: True, Holiday: False -> Day off: {day_off}") # Output: True is_weekend = False is_holiday = False # Both conditions are False day_off = is_weekend or is_holiday print(f"Weekend: False, Holiday: False -> Day off: {day_off}") # Output: FalseHere's the summary for or:Condition 1Condition 2Condition 1 or Condition 2TrueTrueTrueTrueFalseTrueFalseTrueTrueFalseFalseFalseThe not OperatorThe not operator is simpler. It works on a single boolean expression and reverses its value. If the expression is True, not makes it False. If the expression is False, not makes it True.Think of a light switch. not on means off, and not off means on.is_logged_in = False print(f"Is logged in: {is_logged_in}") # Output: False # Check if the user is NOT logged in needs_login = not is_logged_in print(f"Needs login: {needs_login}") # Output: True is_raining = True print(f"Is raining: {is_raining}") # Output: True # Check if it is NOT raining can_go_outside = not is_raining print(f"Can go outside: {can_go_outside}") # Output: FalseSummary for not:Conditionnot ConditionTrueFalseFalseTrueCombining Logical OperatorsYou can combine multiple logical operators in a single expression. Python evaluates not first, then and, then or. However, just like in arithmetic, you can use parentheses () to control the order of evaluation or simply to make your intentions clearer.age = 22 is_student = True has_coupon = False # Eligible if (age < 25 AND is a student) OR has a coupon is_eligible_discount = (age < 25 and is_student) or has_coupon # Evaluates as: (True and True) or False # -> True or False # -> True print(f"Eligible for discount: {is_eligible_discount}") # Output: True # Change coupon status has_coupon = True age = 30 is_student = False is_eligible_discount = (age < 25 and is_student) or has_coupon # Evaluates as: (False and False) or True # -> False or True # -> True print(f"Eligible for discount (different criteria): {is_eligible_discount}") # Output: True Logical operators are fundamental tools for building programs that can make decisions based on multiple criteria. You will see them used extensively when we discuss control flow structures like if statements in the next chapter, allowing your programs to react differently based on whether complex conditions evaluate to True or False.
