Quick example here to show the usage of try, raise, except, finally in Python:

def divide(a, b):
    try:
        if b == 0:
            raise ValueError("Cannot divide by zero!")  # Raising an exception for zero division
        result = a / b
    except ValueError as e:
        print(f"Error: {e}")
        result = None
    finally:
        print("Execution finished.")  # This runs no matter what
    return result

# Example usage
print(divide(10, 2))  # Normal case
print(divide(10, 0))  # Raising an exception

for the record:

Here are minimalist examples of try/except (or catch) and throw (or raise) in 10 popular programming languages:

1. Python

try:
    1 / 0
except ZeroDivisionError:
    print("Error: Division by zero")
    raise ValueError("Custom error")

2. Java

try {
    int result = 1 / 0;
} catch (ArithmeticException e) {
    System.out.println("Error: Division by zero");
    throw new RuntimeException("Custom error");
}

3. C++

#include <iostream>
using namespace std;

int main() {
    try {
        throw runtime_error("Custom error");
    } catch (const runtime_error &e) {
        cout << "Caught: " << e.what() << endl;
        throw;
    }
}

4. JavaScript

try {
    throw new Error("Custom error");
} catch (error) {
    console.error("Caught:", error.message);
    throw error;
}

5. C#

try {
    throw new Exception("Custom error");
} catch (Exception e) {
    Console.WriteLine("Caught: " + e.Message);
    throw;
}

6. Go

package main
import "fmt"

func risky() error {
    return fmt.Errorf("custom error")
}

func main() {
    if err := risky(); err != nil {
        fmt.Println("Caught:", err)
        panic(err)
    }
}

7. Ruby

begin
  raise "Custom error"
rescue => e
  puts "Caught: #{e.message}"
  raise
end

8. Swift

enum MyError: Error {
    case customError
}

do {
    throw MyError.customError
} catch {
    print("Caught:", error)
    throw error
}

9. Kotlin

fun main() {
    try {
        throw Exception("Custom error")
    } catch (e: Exception) {
        println("Caught: ${e.message}")
        throw e
    }
}

10. Rust

fn risky() -> Result<(), &'static str> {
    Err("Custom error")
}

fn main() {
    match risky() {
        Ok(_) => println!("Success"),
        Err(e) => {
            println!("Caught: {}", e);
            panic!("Throwing error")
        }
    }
}

These examples illustrate basic error handling (try/catch or try/except) and throwing exceptions (throw or raise) across different languages. Let me know if you need any further explanations!
