for iter in range(0, max_iter):
    print("in loop")
    print(w[0:iter])
    print(X[0:iter])

I am currently attempting to access an increasing portion of a numpy array, the problem seems to be the first loop when accessing w[0:0], how else can I query this?

Currently, it outputs [] instead of the first value I was hoping for.

So, use `w[:iter + 1]`? – Unmitigated Apr 21 '23 at 05:05
`for iter in range(1, max_iter+1):`? – mozway Apr 21 '23 at 05:05
Remember that in Python, the end of a range is always exclusive. Thus, `x[0:0]` is always an empty list. To see the first element, you need `x[0:1]`. – Tim Roberts Apr 21 '23 at 05:05
