-                Depending on your knowledge and experience with Python you may be questioning why we are not using the <c>match</c> statement in our Python examples. The answer is that this book currently runs its active code examples using Python 3.7, which does not support the <c>match</c> statement which was introduced in Python 3.10. Below is an example of the <c>match</c> statement similar to our grade method.
+                The <c>match - case</c> statement was introduced in Python 3.10, so doesn't run in earlier version of Python. Here is an example using Python's <c>match - case</c> structure.

-            The <c>switch</c> statement in Java provides a clean and efficient alternative to chaining multiple <c>if-else</c> conditions, especially when comparing a single variable against several constant values. It supports a variety of data types, including primitive types (<c>byte</c>, <c>short</c>, <c>char</c>, <c>int</c>), their wrapper classes, <c>enumerations</c>, and <c>String</c> (introduced in Java 7). Each <c>case</c> within a <c>switch</c> must be defined using a constant expression, and duplicate <c>case</c> values are not permitted. By default, control flow "<c>falls through</c>" from one <c>case</c> to the next unless a <c>break</c>, <c>return</c>, or <c>throw</c> statement is used to terminate execution.
