In many other programming languages, the execution of code starts in a specifically named function (such as main) which is expected to have a specific signature, which allows that function to recei...
I have Box drive on Windows. I use it as a regular folder on the computer. I can store images there. When I store a small number of images (on the order of a couple hundreds) and I do not wait lon...
Usually a random IV is used for encryption with AES in CBC mode, so that key/IV pairs are not reused, which would be a vulnerability. During decryption, the IV of the encryption is required. If de...
I am trying to install the Spacy library in VSCode in a folder with a virtual environment. The output appearing in the terminal is excessively long; I will share it with a pastebin later. My versio...
I'm used to working in Python, but my current project is in C#/.NET and uses log4net for logging. Out of the box, log4net uses an XML file for configuration. I dislike XML and want to use something...
Having recently learned about protocols in Python, I now wonder if you can write a protocol for enumerations. That is, a protocol that says that you are supposed to pass an enum that has certain it...
I've written the following code implementing a state machine in Python, and I'd like some feedback on it. The basic idea is that each state has a set of corresponding actions that trigger a state ...
I want my CLI Python program to schedule a task, and then exit. After some times has passed (say 10 minutes) the task should execute. The task can be a Python method or a shell command, whatever i...
I found a strange expression in some Python code: from library import HOME_DIRECTORY file = HOME_DIRECTORY / "file.json" It seems to be dividing a string by another string in order to do som...

I want to make multiple comparisons at once, of the same type, in a Python program. For example, to check whether all of a certain group of strings are in a longer test string; or whether a specifi...
I am training the following model using Keras as shown: model = tf.keras.models.Sequential([tf.keras.layers.Conv2D(64, (3,3), activation='relu', input_shape=(256, 256, 3)), tf.keras.layers.MaxPooli...
