Consider this code: while(arr[index] != 0) index++; vs while(arr[index] != 0) { index++; } Personally, I prefer the first. The fact that the braces are not needed makes them -- u...
Here in Python, I created a program for this challenge and I'm having trouble debugging it. I already fixed most errors I have on my program but here's what I have left: x=y=z=[];i=0.0;a=int(input...
I'm still in the process of making MarkFuncs and having given up from copy-pasting open-source interpreters, them using OOP too, I decided to make one without OOP and with scratch alongside with th...
Now I build a Python script to execute automaticaly a dynamic analysis on apk and I block because I use this library and call objection. When I run my script, the objection command creates an inst...
I have a list of 11-digit numbers stored in one single column in Excel, and I need to separate the digits according to this pattern: 2-2-1-3-3. Example: 00002451018 becomes 00 00 2 451 018. How c...
Based on my last question comes new one. How to loop over 300 000 rows and edit each row string one by one? I have a list of 11-digit numbers stored in one single column in Excel, and I need to s...
What exactly is the Python Global Interpreter Lock (GIL)? As someone who is relatively new to Python, is this something I need to be aware of, or is this just some implementation detail of the inte...
There's this new challenge on Code Golf CD and I'm using Python to do it. A little bit of golfing already took place, so the code might look a bit messy for you. Anyway, I'm proud of what I've writ...
I started adding types to my (working) solution to Exercism's "Kindergarten Garden" exercise, to learn how typing with python and Mypy (strict) works. While doing so, I ran into a Mypy error that I...
Hello everyone, I am seeking help with understanding why multithreading does not work correctly in this example: import time import matplotlib.pyplot as plt import concurrent.futures voltage...
I have a dataset of car bookings like this: car_id user_id 1 1 2 1 1 2 3 3 1 2 3 3 In this dataset, two separate groups/sets of cars and users...
Is it possible for a Python program to send itself in the background? For example, on Linux you can do nohup some_cmd & and any program will run in the background. Some programs also support s...
I want to write one or more self-answered Q&As on the topic of text encoding in Python, to serve as canonicals and preempt future lower-quality questions. I can think of the following things th...
I would like to use tf.timestamp() when it is available (eager mode and graph mode without XLA), and use 0. (or a better fallback if there is one) when it is not available (with XLA; @tf.function(j...
I have a Python program like this: done = False while u and not done: i = u.pop() print(f"Processing {i}") do_big_task(i) finish_up() Since this takes a long time, the user m...
Background Many Python programs now recommend installing with pipx, and there is a sense that you shouldn't install with pip anymore, you should use tools like pipx. Main Question However, what ...
I just noticed this question about data structures in the Q&A. Although algorithms and data structures are often (part of) a solution to a problem when writing software, this question is const...
In VS Code, is it possible to run Python code on the text being edited? I realize that I can save my text, create a .py file, switch to a terminal (including VS Code's own terminal) and run the .p...
Sometimes code needs to assign (or otherwise use) a value that depends on some condition. The naive approach is to use explicit branching, which in Python would look like: if some_condition(): ...
tl;dr: When a question is unclear, don't close right away, especially if it's possible to discern what they are trying to ask. Instead, use comments and edit suggestions to work with the asker and ...
When you try to do a privileged systemd operation without the privilege, you get an escalation prompt: $ systemctl stop docker ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ==== ...
I have multiple installations of Python on my machine. When I run Python, what determines which installation is used? How can I control this?
As part of a general effort to produce basic Q&As for Python, recently I've been focused on issues related to starting up an interpreter and running the code - so, questions about setting up an...
It seems that year over year, computers constantly get easier to use, and it becomes easier for people to start learning to program who have never touched it before. This comes with the consequence...
As far as I can tell, there are no tags yet for the main Q&A. I suggest setting an initial group of tags which help organize questions. Two groups I think would be particularly helpful are lang...
