In this challenge, you need to write the function body for aVeryBigSum, which gets an array of integers, and has to return the sum of this array. Both Python 3 and Perl 6 handle the large integers transparently for you, so I was able to use the same code as I used for the simple array sum challenge.

We have already tried to explain that a for-loop variable in Python can iterate not only over a range, but generally over all the elements of any sequence. Sequences in Python are lists and strings and some other objects that we haven't met yet. Look how you can print a two-dimensional array, using this handy feature of loop for.

Aggregation and Grouping. An essential piece of analysis of large data is efficient summarization: computing aggregations like sum,. insight into the nature of a potentially large dataset. In this section, we'll explore aggregations in Pandas, from simple operations akin to what we've seen on NumPy arrays. 15/02/2017 · The Case2 is testing thousand number so we must using longint, and array range is 1.1000 Thanks for the answers everybody !!!! [/quote] Actually, the C example allocated the array dynamically, just like in my last example. So using a fixed array length is wrong. And you don't have to use longint. That is merely a different way of writing integer. The most obvious examples are lists and tuples. See the documentation for array for details for its use. Some objects may support the array-protocol and allow conversion to arrays this way. A simple way to find out if the object can be converted to a numpy array using array is simply to try it interactively and see if it works!
