💡 Replacing if-else with Match-Case

Starting with Python 3.10, we have a powerful tool: Structural Pattern Matching (match-case). This is not just an analog of switch-case from other languages; it's much more flexible. 🚀

Imagine you're writing a command handler for a bot. 🤖

How NOT to do it:

def handle_command(command):
if command == "start":
return "Hello! I'm a bot."
elif command == "help":
return "Here's a list of available commands..."
elif command == "stop":
return "Goodbye!"
else:
return "Unknown command."

How to do it properly:

def handle_command(command):
match command:
case "start":
return "Hello! I'm a bot."
case "help":
return "Here's a list of available commands..."
case "stop":
return "Goodbye!"
case _: # The underscore symbol catches everything else (default)
return "Unknown command."

The code looks like a clear table, and your eye doesn't get caught up in a bunch of elif statements. 🧐
You can pass data structures in the case statements and check their structure and content on the fly. 🔍
It's easy to combine cases. 🧩

Python has a built-in topological dependency sorter!🚀

If you're working with tasks that have dependencies — for example, in build systems, CI/CD pipelines, or workflow orchestration — the order of execution often has to be determined manually.

Usually through graphs, DFS,, or custom execution order logic.

But Python's standard library already has graphlib.TopologicalSorter.

ts = TopologicalSorter()
ts.add("deploy", "test")
ts.add("test", "build")

After preparation, the sorter returns the correct execution order.

tuple(ts.static_order())

Result:

("build", "test", "deploy")

Especially useful for workflow management systems, dependency resolution, orchestration systems, and any tasks with a dependency graph.

🔥 TopologicalSorter allows you to solve dependency problems using Python's built-in tools without having to implement graph algorithms manually.
