🚀 Python 3.12: New Features and Performance Boosts

Python 3.12 brings major improvements in terms of performance, syntax enhancements, and security. Let's explore what's new in this release!


🔥 Performance Improvements

1️⃣ Faster CPython Execution

Python 3.12 includes enhancements that improve the speed of CPython by optimizing internals, bytecode execution, and memory usage.

Benchmarks suggest a 5-10% speed improvement in real-world applications compared to Python 3.11.

2️⃣ Optimized Frame Stack Handling

A major refactor of frame objects has reduced memory overhead and improved function call performance.

import dis

def sample_function():
    return sum([i for i in range(10)])

print(dis.dis(sample_function))  # Improved bytecode execution

🎯 New Features in Python 3.12

1️⃣ Enhanced f-string Debugging

Python 3.12 makes debugging easier with enhanced f-strings.

x, y = 10, 20
print(f"{x + y = }")  # Output: x + y = 30

2️⃣ More Flexible Type Hints

Type annotations have improved, making static typing more powerful.

from typing import Self

class Example:
    def chain(self) -> Self:
        return self  # Uses Self instead of Example

3️⃣ New except* Syntax for Exception Groups

Introduces structured error handling for handling multiple exceptions.

try:
    raise ExceptionGroup("Errors", [ValueError("Invalid"), TypeError("Wrong Type")])
except* ValueError as e:
    print("Caught ValueError:", e)
except* TypeError as e:
    print("Caught TypeError:", e)

🛠️ Deprecated Features and Changes

  • Python 3.12 removes legacy Unicode C APIs for better Unicode handling.
  • distutils module is fully removed; use setuptools instead.
  • Some older syntax patterns now raise SyntaxWarnings.

📌 Conclusion

Python 3.12 is a faster, more efficient, and more developer-friendly update with notable syntax improvements and performance gains. Upgrade today and take advantage of these powerful new features!
