Should you be using Pathlib?

I've been working in Python for four years - recently I made the conscious choice to use pathlib rather than the more familiar os & os.path.

It's been a great experience - I wrote a short piece (friend link) comparing the two libraries on common workflows & tasks done with file paths.

models.DateTimeField() arguments to add an hour

I'm trying to make a reservation app and I'd like to make a single check in time that automatically creates a checkout time of an hour to hour and a half and I'm having trouble finding the right documentation for it I've tried timedelta but it's not working write either and i don't know what arguments to pass in DateTimeField documentation just shows auto\_now

class Reservations(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
table = models.ForeignKey(Table, on_delete=models.CASCADE)
check_in = datetime()
bookedTime = 1
check_out = check_in + timedelta(hours = bookedTime)

I've also tried models.DateTimeField() but I'm at a loss when it comes to adding a integer to the hour

I made a game in 1 minute in Python

Yes, seriously. Yes, from scratch. But yes, not unprepared.

Video | Source code (skip to 0:59 to skip the intro/context)

Yes, it is quite simple, but provided such a short amount of time, the game turns out to be surprisingly fun. And it also takes much more time to complete the game than to create it:) It’s probably not very educational, but it’s interesting to know that it can be done. Any feedback on the video and ideas regarding the game are appreciated. I am also curious if anyone knows the optimal strategy for this game. There are actually two (possibly different) optimal strategy questions here:

1. Strategy for minimum average number of turns
2. Strategy for minimum worst-case number of turns

[AF] How to have multiple object input with ability to add / delete rows?

I'm sorry if this has been asked before (I did some searching on this subreddit and googling already), but I am running into some issues with trying to use flask. Most of my background is in backend development, and the front end experience that I do have is exclusively in SalesForce (both VisualForce and Lightning), so it doesn't exactly help me much in this situation. That being said, since SalesForce isn't exactly like most other web development, I am not sure how much of my issues are about my lack of regular web development knowledge vs. just not knowing flask, so any help would be appreciated!

I am currently trying to build a Web Application that will do the following:

1. User uses a unique URL with a unique ID that is previously generated.
2. Using the Unique URL, we grab some information about the user to display (email, project, etc.).
3. We also create an instance of an object that the user will enter information on. This object can just be called process_step, and is used to track steps of a process that the user has taken thus far.
4. Render the template with one instance on the page for the user to enter

Hello fellow Djangoers! I'm posting a GitHub Gist in hopes that you will review it! I'm always really curious how people go about organizing Django apps. For instance in the add_promotion method I originally had the get object in the method itself, but then I decided to move it out. How would you go about organizing this? Please help!

I built a flask site that combines stock posts from different social medias and keeps track of the most talked about tickers

hey everyone,

Using flask I built a site that takes stock related posts from 10 different subreddits, as well as from thousands of users on twitter, tiktok, and youtube and combines them into one searchable place. it's been a pretty fun project that has taken me a couple hundred hours to complete and I'm really happy how it turned out. It has served me as a useful tool for investing if any of you are interested in that. Would love to hear any thoughts, feedback, ideas. Thanks!

I Made A Whatpulse Alternative! My Biggest Python Project Till Now!

Hello fellow redditors, thanks for checking this post.

WhatPulse is a small application that measures your keyboard/mouse usage, down- & uploads and your uptime. What I care about is the keyboard and mouse usage. I just like knowing how many clicks it took for that peripheral to fail. The issue I had with Whatpulse tho is that whenever my pc shuts down unexpectedly, the data gets corrupted and I start from 0 again. That happened a couple of times and it annoyed me so much that I decided to make my own program that will achieve the same thing and will save the data in a .txt file so that I can modify it easily if I wanted.



After 5-10 hours of work on it, this is what I ended up with. I think I spent more time than I should but I would blame that on the fact that I had to learn many new things like multi-threading. I tried my best to keep the code clean but I think it still looks messy. I also used the .pyw file extension instead of .py because I don't want the terminal to open. I have around 20 hours of learning
