Thank you very much, Oscar.
Using the following code looks like a much better solution than my current

np.gcd.reduce(np.transpose(a))
or
np.gc

Of course there are other techniques in how code is refactored or the order of

Dear Sirs.
Does NumPy provide a simple mechanism to identify relatively prime integers,
i.e. integers which don't have a common factor other than +1 or -1? For

What decision? To not release any new versions of Python 2? That isn't
actually the OP's problem here - the Python interpreter runs just

In my small way, I can confirm. In one of my previous works, we used
numpy and Pandas. Writing the code in Pandas is quick, but they just
realised that was really slow, and they tried to transform as much
Panda code to numpy code as possibl
ing use of either package, so my
only basis for commenting is what I've read on web sites (like the pandas

Definitely it sounds like you may use both. Quite a bit of what people do using
DataFrame objects includes working on copies of individual columns, which often
are numpy Series or the like and in the other direction, can be used to create
or amend a pandas DataFrame. Plus, many operations used

I don’t know but in case you don’t get other good answers, I’m pretty sure
Numpy is more of a mathematical library and Pandas is definitely for

Never mind, I found the numpy.copy function does what I need. Revised code
below works.
Sorry for wasting bandwidth.

Why isn't the final value of the numpy array npary in the following code the
same as the initial value before some but not all elements of the array were
changed to a new value?

concepts of immutable vs mutable value

you mean by 'inbuilt syntax'.
I presume that numpy cov calls 1 or more functions from the included

Hi,
is it possible to append data to or remove data from numpy arrays like
Python lists? I have some code where I currently use lists and often
do things like
a.append(elem)
a += b
del a[:-n]
I am thinking of changing to numpy arrays but it seems I cannot modify
numpy arrays like

I’ve just begun a serious study of using Python as an aspiring programmer/data
scientist.
Can someone please walk me through how to download Python, SO THAT I will be
able to import numpy?
Thanks,
Derek

python newbie. I can't understand the following about numpy arrays:
x = np.array([[0, 1],[2,3],[4,5],[6,7]])
x
array([[0, 1],
[2, 3],
[4, 5],
[6, 7]])
x.shape
(4, 2)
y = x[:,0]
y
array([0, 2, 4, 6])
y.shape
(4,)
Why is the shape for y reported as (4,) ? I expected it to

I think the line kinda blurs here. This would be a feature of a core
data type, and in CPython, it would
