numpy.ndarray' object is not callable

[natareid]

Hi,

I'm new to python and I'm trying to call a function and use it to calculate the median of a dataset but when I run it I get the following error:

if n % 2 == 0:
    a_median = a(n / 2) + a((n / 2) -1) / 2
else:
    a_median = a[n//2]

Error:
TypeError: 'numpy.ndarray' object is not callable

I have tried to look about online to resolve this and I can see that it's something relating to calling an array as a function, but I don't know what that means or how to fix it.

To call an object in python you use (), a ndarray is not a callable object, use [] instead.

Thanks for getting back to me. I'm really not sure where I'm meant to put the "[]" brackets. I've tried multiple different places (including all of them on the line with the equation) but then I get an error reading

"IndexError: only integers, slices (:), ellipsis (...), numpy.newaxis (None) and integer or boolean arrays are valid indices"

Again, I'm very new to all of this so apologies if I'm missing something glaringly obvious.

In line 2 replace every open paren with an open bracket, and every close paren with a close bracket.

numpy.median(arr, axis = None)
