Python evaluates them left to right, and all comparisons must be true for the entire expression to be true: Chained comparisons are especially useful in data validation, where you frequently need to confirm values fall within acceptable ranges: Practical Range Checking Chained comparisons are perfect for validating that values fall within expected ranges: Chaining Comparisons You can also chain equality operators, which is useful for checking if multiple values are equal: Chained comparisons are especially easy to get wrong when combining inequality operators. The safest approach is to read the chain aloud as a mathematical expression: "Is value at least 0 and at most 100?" maps directly to "0 <= value <= 100". When
