Logical Operators and Grouping Conditions

Boolean values become much more useful when you combine them. This Block introduces Python's logical operators: and, or, and not. You will use them with boolean variables and comparisons to build practical rules for age ranges, permissions, account access, weekends, holidays, and similar everyday decisions.

You will also learn how parentheses group conditions, why grouping can change the result of an expression, and how Python evaluates not, and, and or when parentheses are not present.

What you will learn:

• Require multiple conditions with and
• Accept alternative conditions with or
• Reverse boolean values with not
• Combine logical operators with comparisons
• Group related conditions using parentheses
• Understand the evaluation order of not, and, and or
• Avoid common mistakes when checking ranges and multiple alternatives
• Break complicated conditions into clear, well-named boolean variables

By the end, you will be able to translate plain-English requirements into readable Python conditions without turning one line of code into a logic puzzle.
