stricty 0.1.1

strictpy runtime type enforcement for Python — no coercion, no surprises.

🚀 Stricty

Strict runtime type enforcement for Python — no coercion, no surprises.

Stricty makes Python behave more like C/C++ when it comes to type safety. It enforces exact type matching for function arguments and return values at runtime.

✨ Features

• ✅ Strict function argument validation
• ✅ Return type enforcement
• ❌ No implicit type conversion
• ⚡ Lightweight and fast
• 🧠 Clear, developer-friendly error messages

🔥 Why Stricty?

Python is dynamically typed:

def add(x: int, y: int):
    return x + y

add("1", 2)  # ❌ No error by default

Stricty enforces fail-fast behavior:

from strictpy import strict

@strict
def add(x: int, y: int) -> int:
    return x + y

add(1, 2)        # ✅ 3
add("1", 2)      # ❌ StrictTypeError

---

🧪 Return Type Enforcement

@strict
def get_number() -> int:
    return "10"   # ❌ Error

---

⚠️ Philosophy

Stricty follows a simple rule:

"Wrong type? Fail immediately."

No:

• silent conversions
• hidden bugs
• unexpected behavior
