A C++ style vector implementation for Python.

Installation

pip install cppvector-jediz

v = Vector([1, 2, 3, 4, 5]) print("1. SVO test:", v) for x in [999, 111, 222, 333]: v.push_back(x) print(" After overflow:", v)

print("2. After swap():", a, b)
print("   Equality check:", a == Vector([100, 200, 300]))

print("   NumPy view:", arr)

# 5. Speed test
print("\n5. 10 million push_back speed test...")

# 6. Shrink back to SVO
while len(v) > 5:
