What is Numba and how can I use it in Python?

Numba is a just-in-time compiler for Python that translates a subset of Python and NumPy code into fast machine code. You can use it to speed up your numerical computations.

Can you show me a simple example of using Numba?

Sure! Here's a simple example:

from numba import jit

@jit
def sum_array(arr):
    total = 0
    for i in arr:
        total += i
    return total

print(sum_array([1, 2, 3, 4, 5]))

What are the benefits of using Numba over regular Python?

The main benefits of using Numba include significant speed improvements for numerical computations, easy integration with existing Python code, and support for NumPy arrays.

Are there any limitations I should be aware of?

Yes, Numba works best with numerical functions and has limitations with certain Python features like dynamic typing and some built-in functions.
