Editor to share with you how the python list is divided into uniform blocks. I hope you will get something after reading this article. Let's discuss it together.

1. Generate the generator of the desired block.

Def chunks (lst, n): "Yield successive n-sized chunks from lst." For i in range (0, len (lst), n): yield lst [ilst + n] import pprintpprint.pprint (list (chunks (range (10, 75), 10)) [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34, 35, 36, 37, 38, 39], [40, 41, 42, 43, 44, 45] 46, 47, 48, 49], [50, 51, 52, 53, 54, 55, 56, 57, 58, 59], [60, 61, 62, 63, 64, 65, 66, 67, 68, 69], [70, 71, 72, 73, 74]]

2. If you are using Python 2, use xrange () instead of range ().

Def chunks (lst, n): "Yield successive n-sized chunks from lst." For i in xrange (0, len (lst), n): yield lst [ilst I + n]

3. You can simply use list derivation instead of writing functions.

Just wrap this operation in a named function to make the code easier to understand.

[lst [len I + n] for i in range (0, len (lst), n)] Python 2 version: [lst [ilen I + n] for i in xrange (0, len (lst), n)] after reading this article, I believe you have a certain understanding of "how the python list is divided into uniform blocks".
