What are the limitations of pattern matching in Python?

Pattern matching in Python, introduced in version 3.10, has some limitations. For instance, it doesn't support matching against all data types, and complex patterns can lead to performance issues.

Can you give examples of data types that can't be matched?

Sure! For example, you cannot use pattern matching with certain types like sets or dictionaries directly. You can only match against sequences, mappings, and certain classes.

What about performance issues? Can you elaborate?

Certainly! While pattern matching is generally efficient, using deeply nested patterns or matching against large data structures can slow down performance due to the complexity of the matching process.

Are there any workarounds for these limitations?

Yes, one workaround is to use traditional conditional statements like if and elif for complex cases. You can also break down patterns into simpler components to improve readability and performance.
