Logical operators<\/strong> are used to combine conditions<\/strong>.<\/p>\n They help Python decide:<\/p>\n Yes or No<\/p>\n<\/li>\n True or False<\/p>\n<\/li>\n<\/ul>\n Python has three logical operators<\/strong>:<\/p>\n print<\/span>(age >= 18<\/span> and<\/span> has_id) Output:<\/p>\n if<\/span> marks >= 40<\/span> and<\/span> attendance >= 75<\/span>: print<\/span>(is_weekend or<\/span> is_holiday) Output:<\/p>\n if<\/span> day == \"Saturday\"<\/span> or<\/span> day == \"Sunday\"<\/span>: Output:<\/p>\n if<\/span> not<\/span> is_logged_in: Logical operators are often used with comparison operators.<\/p>\n print<\/span>(age > 18<\/span> and<\/span> age < 30<\/span>) user = input<\/span>(\"Enter username: \"<\/span>) if<\/span> user == username and<\/span> pwd == password: True and True \u2192 True<\/p>\n<\/li>\n True and False \u2192 False<\/p>\n<\/li>\n<\/ul>\n False or True \u2192 True<\/p>\n<\/li>\n False or False \u2192 False<\/p>\n<\/li>\n<\/ul>\n not True \u2192 False<\/p>\n<\/li>\n not False \u2192 True<\/p>\n<\/li>\n<\/ul>\n \u2714 Correct:<\/p>\n \u2714 Correct:<\/p>\n print<\/span>(age >= 18<\/span> and<\/span> age <= 60<\/span>) print<\/span>(is_child or<\/span> is_senior) print<\/span>(not<\/span> logged_in) \u2714 Used to combine conditions This chapter is ideal for:<\/p>\n Python beginner books<\/p>\n<\/li>\n School & college students<\/p>\n<\/li>\n Self-learners<\/p>\n<\/li>\n<\/ul>\n If you want next, I can write:<\/p>\n\n

and<\/code>)<\/h2>\nand<\/code> means both conditions must be True<\/strong>.<\/p>\nExample<\/h3>\n
age = 20<\/span>
\nhas_id = True<\/span><\/p>\n
\n<\/code><\/div>\n<\/div>\nTrue
\n<\/code><\/div>\n<\/div>\nReal-Life Example<\/h3>\n

\n print<\/span>(\"You are allowed to sit in exam\"<\/span>)
\n<\/code><\/div>\n<\/div>\n3. Logical OR (
or<\/code>)<\/h2>\nor<\/code> means at least one condition must be True<\/strong>.<\/p>\nExample<\/h3>\n
is_weekend = False<\/span>
\nis_holiday = True<\/span><\/p>\n
\n<\/code><\/div>\n<\/div>\nTrue

day = \"Sunday\"<\/span><\/p>\n
\n print<\/span>(\"Today is a holiday\"<\/span>)
\n<\/code><\/div>\n<\/div>\n4. Logical NOT (
not<\/code>)<\/h2>\nnot<\/code> means reverse the result<\/strong>.<\/p>\nExample<\/h3>\n
is_raining = False<\/span>
\nprint<\/span>(not<\/span> is_raining)
\n<\/code><\/div>\n<\/div>\nTrue

username = \"admin\"<\/span>
\npassword = \"1234\"<\/span><\/p>\n
\npwd = input<\/span>(\"Enter password: \"<\/span>)<\/p>\n
