python split array into chunks based on value

specifies the number of equal chunks: split works the same but raises an exception if an equal split is not possible. Observation of the data leads to the conclusion that you should pick a combination of rows and columns whose sum is the smallest: Unsurprisingly, the four-by-four chunk is the squarest of them all. Loop through the number of chunks. 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. Please refer to the split documentation. ]), array([6., 7., 8. List comprehensions in Python have a number of useful benefits over for-loops, including not having to instantiate an empty list first, and not having to break your for-loop over multiple lines. You might become tempted to go overboard and split your data into more chunks than you have CPU cores.
