The bytes type in Python is immutable and stores a sequence of values ranging from 0-255 (8-bits). This can be used in handling binary data. Python also allows negative indexes into a string, which is a feature many other languages do not support. It uses a binary encoding (based on mp4 boxes, naturally) and stores information separately from the text itself. shape = [batch_size, d0,. Ship high performance Python applications without the headache of binary compilation and packaging.

Python allows you to build scripts to automate complex network configuration. Nevertheless, we cannot directly concatenate a string and an integer. A slicing operation creates a view on the original array, which is just a way of accessing array data. The difference between sort and sorted is that sort is a list method that modifies the list in place whereas sorted is a built-in function that creates a new list without touching the original one. The simplest thresholding methods replace each pixel in the source image with a black pixel if the pixel intensity is less than some predefined constant(the threshold value)or a white pixel if the pixel intensity is greater than the threshold value. These are Python's bitwise operators. A class is a collection of variables and functions working with these variables.
