Here's a JSON log formatter for Python. I want to be able to log details of exceptions (and have some capability to debug-by-logs). I want to be able to log extra data in JSON format (in addition...
I tried installing Python on an old computer running Windows 8[1]. I know for a fact that there was never any previous installation of Python on the machine. The installation appeared to be success...
My (non-Windows) operating system came with Python, but that Python didn't include Pip. I followed instructions to install Pip for the included Python, using my system's package manager. But now w...
When I want to print a number or a string, I can use f-strings (Python >= 3.6) or str.format, and I can use just the variable between braces, or use format specifiers. Ex: num, text = 10, 'abc' ...
Summary I'm building an internal system (hardware simulator, using Rust) to help test some Python-based services that talk to hardware. (The services talk to hardware via TTYs.) To trick the Pytho...
When running various Python scripts, I often need to do this annoying dance: $ python script.py ... ModuleNotFoundError: No module named 'foo' $ pip install foo $ python script.py ... Module...
I already know that the pip command might not correspond to the same Python that python runs. But in my case, it seems not to exist at all. I can't even run it as a Python module: $ python -m pip ...
I used to have some testing code for mocking a simple directory structure when working with pathlib. I recently tried to run these tests to learn that some of the internals in pathlib have changed ...
Suppose I have some variables like: >>> count = 8 >>> status = 'off' I want to combine them with some hard-coded text, to get a single string like 'I have 8 cans of Spam®; b...
Is there some sane way to allow Python to import from subfolders in projects that don't have a package? I have many Python programs that I implemented as Python files inside a directory, without a...
I know that I can make Python code run starting from the script, but this still requires the user to have Python installed (and will still rely on configuring the system so that it can find Python ...
I had understood that Python is supposed to come "batteries included", and that the "batteries" specifically include: the tkinter standard library, a simple GUI framework a simple IDE cal...
I often see the construct if __name__ == '__main__' in Python code. For example, the queens.py demo in the Python repository ends with these two lines: if __name__ == "__main__": main() Ho...
In Python 2, I was able to create a file named .env within a project folder like so: # .env MY_ID=abc123 TOKEN=4567890 Then in a Python file in the same directory, I could read these variable...
In Python, multiprocessing is easy to do if you follow a "list projection" paradigm. Say you want to take a list of inputs X and apply some function f to every x_i, such that y_i = f(x_i) and the y...
A well-known easter egg in Python displays some ideas about writing good Python code, credited to Tim Peters (one of the core developers). This question is about the last: Namespaces are one hon...
PEP20 aka the Zen of Python has a statement: Namespaces are one honking great idea -- let's do more of those! What exactly are we supposed to "do" according to this? Is it saying we should h...
I have multiple installations of Python on my machine. I already know how to choose one to use to run for my code - and therefore, I could also solve the problem for third-party application code. ...
I have already learned how to tell the Python interpreter to run my code, but the standard approach feels a little unsatisfactory. I want the user experience to be that my program starts with the a...
I tried installing package-installation-test[1] using Pip, and it appeared to be successful. But I can't use it as advertised, either by itself or by importing it from my code: Failed attempts ...
I'm building a Flask application with user login functionality using Flask-WTF for form handling and Flask-Login for user authentication. However, I am unable to log in successfully. The page does ...
I have a small new Python 3.8 Flask project with some relative import quirks. For the DB I use SQLAlchemy with Flask-Migrate. My project has the following general structure: controllers/ static/ te...
I've just started playing around with pygame and have written a small game in it, of which I'd like a review. Note that I'm not only a complete beginner in pygame, but I also have very little exper...
I have a Python script that needs to access some data (or configuration) file in its very own folder. For example, say script.py does something like this: with open('data.txt') as file: data ...
I have console scripts in my virtual environment in \env\Scripts, installed with packages (e.g. black, pytest, coverage). If I try to execute these in Git Bash, the output is not returned to the te...
