What are some examples of using Numba in Python?

Numba is a just-in-time compiler for Python that can speed up your code. For example, you can use it to accelerate numerical functions.

Can you show me a simple example?

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

This function will be compiled by Numba for faster execution.

How much speedup can I expect?

The speedup can vary, but many users report improvements of 2x to 100x, depending on the complexity of the function and the size of the data.

Are there any limitations to using Numba?

Yes, Numba works best with numerical functions and may not support all Python features. It's ideal for array-oriented computations.
