Supercharge your code with Python's 'match' statement
summary
Explains that Python’s match is structural pattern matching, not a fancy switch, and shows concrete rewrites: replace nested ifs and tuple unpacking with cases that capture values like ("ok", id) vs ("error", code) so the code becomes three concise cases; applies to dicts (GraphQL responses: errors vs data→hero→friends), lists, dataclasses and normal classes via the match protocol, and lets functions return different structures easily. Notes a bytecode speedup, a gotcha where bare names capture like variables, and the enum fix.
