python split array into chunks based on value

Split array into multiple sub-arrays along the 3rd axis (depth). n is the length of chunks. , . The last chunk is padded with None values until it is the proper length. In other words, you need to find pairs of whole numbers whose product gives the desired number of chunks. They make a lot of Python methods easy to implement, as well as easy to understand. Just seems a little more Pythonic and readable to me! Otherwise, feel free to take for granted that it works correctly and move on. In order to give the ability to read and update the value of a pixel, you can implement these two special methods in your class: They both calculate the pixels coordinates relative to the origin of its containing chunk by offsetting the absolute coordinates accordingly. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? Note that because it returns an iterator, the result can only be consumed once.

If you want to have the chunks as evenly sized as possible: In cases, where your list contains elements of different types or iterable objects that store values of different types (f.e. Once you have them, you can pick the most even one by calculating the sum of each tuple: You associate each product with the corresponding sum by placing them in a Python dictionary, and then return the product with the smallest sum: In this case, the number of rows and columns that produce the most even chunks is four by four. Upvoting because of the not using short variables, and test cases. I need to send an array by 'packages' of specific length (say 40 bytes) using TCP Protocol and Python's socket module. The solution(s) below have many advantages: The code above produces the below output for l = range(16) and n = 6: If you need the chunks to be sequential instead of striped use this: Which for l = range(16) and n = 6 produces: See this stackoverflow link for more information on the advantages of generators.

However, the function only works with numeric values (as NumPy arrays can only contain numeric values). Adding one additional core cuts the time nearly in half, which makes sense because your computer does twice as much work in the same amount of time. Join a sequence of arrays along a new axis. This can be done as follows: Assuming you want to divide into n chunks: This method simply divides the length of the list by the number of chunks and, in case the length is not a multiple of the number, adds the extra elements in the last list. and the rest of size l//n.

If the start is non-zero, the iterable elements will be skipped before the start is reached. Because the number of dimensions can vary, you may implement a generic solution with the help of the starmap() and product() functions from the itertools module: This function yields objects of a custom Bounds type, which allows you to retain the spatial information of each chunk regardless of the number of dimensions. Here, we are using a Numpy.array_split, which splits the array into n chunks of equal size. The .split() method is a beneficial tool for manipulating strings.
